The 14.4Kbps modem option and other option boards have also been approved by the British Approvals Board for Telecommunications (BABT) and have been granted the Conformité Européene (CE) mark. For more information, see the documentation for the specific options.
This guide contains information that must be followed to ensure safe operation and maintenance of the timeclock. Failure to follow a warning statement can result in personal injury.
Cleaning the Timeclock
It is important to keep the 400 Series Timeclock case clean in order to prevent dirt and grease from obscuring the timeclock’s LCD display or from possibly getting inside the badge reader.
Follow these steps to clean the 400 Series Timeclock’s case and keyboard: 1. Using a soft, lint-free cloth, and a spray bottle of glass cleaner, clean the
outside of the 400 Series Timeclock’s cover and case. Do not spray the cleaner inside the timeclock’s case. (When cleaning the timeclock’s case, spray the cleaner on the cloth—do not spray the cleaner directly on the timeclock.)
2. Clean the polycarbonate lens that covers the timeclock’s display.
Caution
Do not use steel wool, or any other abrasives, or solvents such as alcohol, benzene, or acetone, as they can damage the timeclock.
Before You Call Support
If you are having a problem, do the following:
M Check the physical connections; for example, check the LED lights and the link lines. Check the connections of any plug-ins.
M Verify the timeclock configuration; for example, is the timeclock’s password and IP address correct? Also, verify the procedures you used to configure the timeclock.
M Check the network connection; that is, check the link on the port that the timeclock is connected to at the hub or switch and verify the circuit and wiring.
M Ping the timeclock from the host PC if your timeclock has an Ethernet board. If you can ping the timeclock, but it still won’t collect or update data, check to see if it is a duplicate IP address problem. To do this for a timeclock with an Ethernet board, unplug the Ethernet cable from the back of the timeclock. If you can still ping the timeclock, another device shares the IP address. For information on how to ping the timeclock, see the section “Ping Utility” in Chapter 4.
If you cannot ping the timeclock, the PC host may be communicating to the timeclock through a switch or some other device.
Caution
If you change anything, and the problem still exists, go back to the original situation. Do not try to change something else at that point, because you may introduce another problem.
Preventive Maintenance
The 400 Series Timeclock requires periodic preventive maintenance to ensure trouble-free operation. ADP recommends that the timeclock receive preventive maintenance once a year.
This chapter contains the following sections:
M The Lithium Battery
M The Lead-Acid Battery
The Lithium Battery
Each 400 Series Timeclock is equipped with a 3 VDC lithium battery that protects data stored in the timeclock’s RAM. The battery also powers the timeclock’s internal real-time clock if external power is lost. You cannot read badges or make keypad entries while the timeclock is operating on lithium battery backup.
Each time you restore external power to the 400 Series Timeclock after it has been operating on lithium battery backup, the timeclock updates the amount of time the timeclock has been operating on battery backup and sizes the installed RAM. The timeclock displays the message LOW LITHIUM BATTERY if the battery is within 14 days of its limit.

Servicing the 400 Series Timeclock
Servicing the 400 Series Timeclock consists mainly of saving and restoring the timeclock’s data and removing and replacing malfunctioning components of the field replaceable unit (FRU). Instructions are also included for upgrading memory.
This chapter contains the following sections:
M Handling Static-Sensitive Components
M Saving and Restoring Data
M Removing and Replacing Parts of the Timeclock
M Upgrading Memory
Note
When servicing the 400 Series Timeclock, collecting data from the timeclock is not always an adequate method of saving employee data, as the latest punch status (in or out) is lost on power-up (if the lithium battery is disabled). Prior to servicing the 400 Series Timeclock, you must save its data by following the steps in the “Saving and Restoring Data” section in this chapter.
Handling Static-Sensitive Components
Many assemblies in the 400 Series Timeclock have static-sensitive components. Static electricity can cause hardware components to fail.
You can damage components if you do not take the following precautions:
M When handling a static sensitive assembly (such as a printed circuit board) for any reason, first put on an Anti-Static wrist strap. Wrap the conductive wrist strap around your wrist so that it is comfortable, and secure the fastener. Be sure the other end of the strap is grounded.
M When you finish handling the assembly, replace it in the 400 Series Timeclock, or place it on a grounded conductive surface.
M When shipping or storing a printed circuit board, always place the board in a conductive shipping bag or carton.
Saving and Restoring Data
When servicing the 400 Series Timeclock, you may encounter various reasons for disconnecting the timeclock from its power source. For example, you may have to remove and replace the timeclock’s lithium battery, or you may have to replace the timeclock itself. Disconnecting the timeclock causes the timeclock to lose its stored data. Before disconnecting the timeclock for any reason, you must save the data in the timeclock so important information is not lost. After you finish servicing the timeclock, you must then restore the timeclock’s data.
ADP provides service utilities for Windows and DOS systems that you can use to save and restore the 400 Series Timeclock’s data.
Terminal Service Utility
You can use the utilities of the Terminal Service Utility (TSU) application to save and restore data in a Windows environment. The application includes the
following utilities:
M Check
The Check utility reports the current serial parameter settings. It reports the ports available and the baud rate on the Communications Resource Summary screen.
M Setcomm
The Setcomm utility shows the current system settings on the Communications Setup screen. You use this tool to configure serial parameters.
M SL400
You can use the SL400 utility to save and restore data and to update the timeclock’s EEPROM. For information on updating the flash-EEPROM, see Chapter 5, “Changing Timeclock Firmware.”
M SoftLoad
You can use the SoftLoad utility to update the timeclock’s firmware. From the Update Firmware window, you can search for files and browse to change directories.
M Transfer
You use the Transfer utility to transmit commands in a text file from the PC to the timeclock. This utility provides a way to change programming and to obtain programming in a text file. It uses the Arbiter File Transfer (AFT) software. See the 400 Series Timeclock Configuration Guide and the 400
Series Timeclock Host Software Interface Guide for information on using
AFT.
M Tryit
You can use the Tryit utility to test the communications line. For instructions for using Tryit see the section “Tryit Utility” in Chapter 4.
You need just the Setcomm and SL400 utilites to save and restore the 400 Series Timeclock’s data. While using these utilities, you can edit and save text files by accessing the Open option on the Files menu. The default for editing is Notepad, but you can use WordPad if it is in the current directory or path.
Configuring with Setcomm
Before you use the SL400 utility, you must configure the TSU application. To access the Terminal Service Utility application, complete the following steps:
1. Unzip the TERMUTIL.ZIP file and run the SETUP.EXE file. 2. The setup window to install the Terminal Service Utility appears:

3. Click the Save button and then click the OK button to save these settings. Setcomm creates a COMMLINK.CFG file in the directory that you select.
Saving the Timeclock Parameters
To save the timeclock parameters, use the SL400 utility.
Caution
Before you collect the timeclock parameters, be sure to collect the punch data from the timeclock using your host software.
To access the SL400 utility from the Terminal Service Utility window, select
Tools > SL400. The SL400 dialog box appears:
To save the timeclock parameters, complete the following steps:
1. Check the Save Program Parameters box, and uncheck the other preferences. 2. Specify the timeclock for which you want to save the parameters. Enter into
the Address field the IP address for Ethernet timeclocks, the telephone number for modem timeclocks, or the password for direct connection timeclocks.
The SL400 utility stores the parameters to a specified file, XXXXXX.PRM. If the timeclock uses serial communications, the X’s in the filename correspond to the six-digit password entered; for example, if the password is 111111, the file is called 111111.PRM. If the timeclock uses Ethernet communications, the X’s in the filename correspond to the last six digits of the timeclock’s IP address.
After you save the timeclock’s parameters, you can now service the timeclock as required.
Restoring the Timeclock Parameters
Before restoring the parameters, you must cold-start and then reprogram the timeclock. For information, see the section “Programming the 400 Series Timeclock.”
To restore the timeclock parameters, complete the following steps: 1. From the Terminal Service Utility window, select Tools > SL400.
The SL400 dialog box appears.
2. Select the Restore Parameters box and clear the other preferences.
3. Specify the timeclock for which you want to restore the parameters. Enter into the Address field the IP address for Ethernet timeclocks, the telephone number for modem timeclocks, or the password for direct connection timeclocks.
4. Click the Update button to restore the timeclock’s parameters.
Other TSU Options
You can use the DataSave and DataRestore preferences on the SL400 window to save and restore all the data in the timeclock. However, the process of saving all the data takes more time than saving just the timeclock’s parameters. However, if you save just the timeclock parameters, remember to reinitialize the timeclock using your host application.
You can also use the SL400 utility to update the timeclock’s flash-EEPROM. For more information, see the section, “Softloading an Application with SL400” in Chapter 5.
SL400 for DOS
A DOS version of SL400 is available for ADP DOS products. You can use this program (SL400.EXE) to save and restore the 400 Series Timeclock’s data. Prior to saving data, ensure that you installed the versions of SL400.EXE,
SETCOMM.EXE, CHECK.EXE, and TRYIT.EXE that are compatible with the installed version of your 400 Series Timeclock application and its associated COMM.FIG file.
The SL400 utility has three options:
M Application update
Use this for softloading an application into the flash EEPROM. See Chapter 5, “Changing Timeclock Firmware” for instructions.
M Terminal Parameters
Use this for saving and restoring the timeclock’s parameters. The process of saving data using this option takes about 30 seconds at a 9600 baud rate; the process of restoring it takes about 1 minute. Prior to using this option, be sure to collect the punch information from the 400 Series Timeclock.
M Datasave
Use this for saving and restoring the timeclock’s RAM data. This option saves all data in the timeclock. The process of saving data using this option takes about 10 minutes at a 9600 baud rate; the process of restoring data takes about the same amount of time. The time will vary based on the amount of RAM (128K or 256K).
Saving the Timeclock Parameters
Follow these steps to save the 400 Series Timeclock’s parameters using the DOS SL400 utility:
2. If this is a new software installation, you need to know your computer’s communication setup specifications before proceeding. To configure Setcomm:
a. Go into the DOS environment and find the directory that contains SETCOMM.EXE.
If the SETCOMM.EXE file is not in the \etime\DATA directory, move it to that directory.
b. At the DOS prompt, enter SETCOMM and press Enter.
c. Edit the information in the opened window to match your system’s communications specifications.
d. Exit from the DOS window. When you exit, the system creates or modifies a COMM.FIG file.
e. Check that the modified or new COMM.FIG file is in the same directory as the SL400.EXE file.
Both files should be in the \etime\DATA directory.
3. To run the SL400.EXE program from the \etime\DATA directory, enter SL400 at the DOS prompt and press Enter.
4. Select the Terminal Parameters option and press Enter. The Terminal Parameters window appears:
5. Select the Store Parameters option and press Enter. The Store Parameters window appears:
6. Enter the password and phone number of the timeclock you are saving the parameters from. If there is no phone used, enter0for the phone number. Press Enter.
The SL400 utility stores the parameters to a specified file, XXXXXX.PRM. If the timeclock uses serial communications, the X’s in the filename correspond to the six-digit password entered; for example, if the password is 111111, the file is called 111111.PRM. If the timeclock uses Ethernet communications, the X’s in the filename correspond to the last six digits of the timeclock’s IP address.When the utility finishes transferring the information, it displays the message:
***Successful Completion***
7. Press any key to return to the Store Parameters screen. You can save another timeclock’s parameters or press Esc to exit from the SL400 application. 8. After you have saved the 400 Series Timeclock’s parameters, you can service
the timeclock as required.
Examining the Timeclock’s Parameter File
After you save the timeclock’s parameters, you can view, print, or modify the information.
M To view the timeclock’s parameter file, use the DOS editor. In the directory where the file SL400.EXE is located, enter the following command at the prompt:
C:\> edit XXXXXX.PRM
Press Enter and the file displays on the screen.
M To print the timeclock’s parameters, press the ALT, F, P keys in sequence. You can choose to print selected text only or the complete document.
M To modify the timeclock’s parameters, highlight or delete the specific information you want to change and type in the new information.
To save the file, press the ALT, F, A keys in sequence. The Save as dialog box appears. Rename the file and save it to any directory. You should rename the file so that the original file will not be modified. It is best to use a file
name that is not the password, because you may want to use only a few files for many timeclocks . You can now use the new parameter file with the changes you made. If you make any changes, be sure to print a copy of the timeclock’s parameters for future reference. To close the DOS editor, press the ALT, F, X keys in sequence.
After you save the timeclock’s parameters, you can now service the timeclock as required. Before restoring the parameters, you must cold-start and reprogram the timeclock.
Restoring the Timeclock Parameters
To program the 400 Series Timeclock before using SL400 to restore the parameters, you need the printed copy of the timeclock’s parameters. For instructions on printing the parameters, see the section “Examining the Timeclock’s Parameter File.”
You can also get the information you need from the timeclock by swiping a maintenance badge and using Command 90, Procedure 9, Step 1, Procedure 10, Steps 1 and 2, and Procedure 30, Steps 1 and 2. Write down the value for a modem (1 if there is a modem or 2 if there is not). Also write down the baud rate, the password, and the IP address before cold-starting the timeclock and beginning the programming procedure. For information on programming the timeclock, see the section “Programming the 400 Series Timeclock.”

Caution
Upgrading the timeclock’s memory will erase all timeclock configuration information and punch data. Before changing the memory configuration, be sure to save the timeclock’s data. See the section “Saving and Restoring Data” earlier in this chapter.
RAM Upgrade
This section contains information you need to upgrade the 400 Series Timeclock’s random access memory (RAM). The two types of mainboard support different RAM configurations.
M Mainboard 6600177-XXX
This mainboard supports memory configurations of 128K and 256K. You achieve the memory configurations by installing either one or two 128K memory chips.
M Mainboard 6600186-XXX
This mainboard supports memory configurations of 128K and 256K. You achieve the memory configurations by installing one or two 128 memory chips. Use the shorting jumpers located at J1 to configure the hardware for 128K memory chips.
Inserting the Memory Chip
During the procedure for installing the memory chip, which is described in “Changing the Memory Configuration,” you need to insert a memory chip into the socket on the mainboard. If you do not insert the memory chip into the socket properly, the chip will not function.
You must first locate Pin 1 of the socket and the memory chip to properly orient the memory chip in the socket on the mainboard. The markings on the mainboard have a rectangular outline for the socket.
M PIN1 on the mainboard is located in the upper left corner, on the edge of the outline that has a notch.
M PIN 1 of the memory chip is noted by a small dot in the upper left corner of the chip.
When you place the memory chip into the socket, align both PIN1 on the chip and the socket. Be sure that the pins go straight into the socket and that the chip sits flat. You must push firmly to seat the chip properly. Be careful not to push excessively or you may bend or break the pins.
Changing the Memory Configuration
To install the new memory chip and change and verify the memory configuration, complete the following steps:
1. Disconnect the wall transformer from its AC power source.
2. Using the Allen wrench, remove the screw on the left side of the timeclock and open the unit.
3. If a battery backup board is installed, unplug the battery backup connection at TB3 on the mainboard.
4. Using the nonmetallic tool, remove the lithium battery at BATT1, by wedging it through the slots on the side of the holder. Take care not to damage the battery holder when removing the battery. For more details, see the section “Replacing the Lithium Battery” in Chapter 2.
5. Before inserting new memory chips into the appropriate sockets, locate the existing memory chips on the mainboard.
On the 6600177-XXX mainboard, the primary memory chip is at location U4; the secondary is at U5. Note that the primary memory chip is soldered to the mainboard; there is a socket for the secondary memory chip.
On the 6600186-XXX mainboard, the primary memory chip is at location U5; the secondary is at U6. Note that both the primary and secondary memory chips have sockets.
– If upgrading a 6600177-XXX or 6600186-XXX mainboard from 128K to 256K, insert the memory chip into the secondary socket.
6. Plug in the battery backup connection at TB3 on the mainboard (if a battery backup board is installed).
7. Install the lithium battery into BATT1, ensuring that the positive (+) side of the battery is positioned on the same side of the holder as the board markings. 8. Close the 400 Series Timeclock, and using the Allen wrench, replace the
screw on the left side of the timeclock.
9. Connect the wall transformer to its AC power source. The timeclock should turn on normally and display:
1/01/96 12:00A OR 1/01/96 12:00A
