Pre-Installation Requirements

In order to support the installation of the Ethernet Option Board, the ADP Series 400 Timeclocks must contain the following:

n A main PC board with part number (P/N) 6600186-xxx. This part number is silk-screened in the middle of the main PC board. Older timeclocks may not contain this board and thus, cannot support the Ethernet option.

n 256K or more of RAM. (NOTE: This is not an issue in most ADP accounts because ADP only supports the Ethernet connection to the 480 Timeclock, which ships with more than 256k RAM)

n A permanently-assigned Internet Protocol (IP) address for the clock. This must be obtained by the client’s network administrator. (NOTE: Ethernet clocks do not support DHCP.)

To determine RAM size:

1 Swipe an authorized maintenance badge or enter a valid mainte-nance Personal Identification Number (PIN).

2 Perform maintenance mode command 110 to display the available RAM size.

Timeclocks with the main PC board other than P/N 6600186-xxx must be swapped out for a new clock.

Installing the Ethernet Option Board

1 Disconnect power supply and detach the back cover from the base of the timeclock. Timeclock power supply includes the AC Adapter and Lead Acid battery backup unit.

2 Insert the plastic Ethernet circuit board standoffs on the Main Board as shown in the illustration that follows.

3 Plug the Ethernet option board (hereafter referred to as the NIC) into connector P3 on the Main Board. The connector is labeled NET BRD. You must align the connector with its socket, while applying equal pressure at the four standoffs and press down simultaneously. 4 Plug the 10BASE-T cable into P1 on the NIC and attach to the

cli-ent's network.(This connection is supplied by the client). Re-attach back cover to base, and connect power supply.

MAC Address

Assigning an IP Address to the Clock

1 Get a valid static IP address from the client’s network administrator.

Note: If you are replacing an existing Ethernet-enabled clock, you

should get a new IP address. This will help prevent commu-nications problems with the new clock. (For those who understand TCP/IP communications: This is because the clock does not broadcast an ARP request at power up. This can lead to a mismatch between MAC and IP addresses in the ARP caches of connecting devices on the network, including the eTIME PC).

2 Swipe a maintenance badge to enter command mode. 3 Press 9, then 0, then ENTER to enter Procedure mode.

4 Go to Procedure 30, Step 1, to enter a six-digit password for the clock.

5 Go to Procedure 30, Step 2, to set the IP address in the clock.

Note: You must obtain a valid IP address from the client. Do not

make this number up!

Useful Maintenance Mode Commands

Command 85: Display Accessory Address

Ethernet (MAC) address is of the form, 00-40-58-XX-XX-XX, where 00-40-58 is the IEEE MAC vendor code, and XX-XX-XX is the IEEE address for the PCB assembly.

Command 139: Re-initialize Accessory Device (in Flash Mode)

Re-initializes the connected accessory device in cold start.

Command 185: Test Accessory Board

Performs tests on the connected accessory device. The diagnostic tests are independent for the device. The following tests are available for the Ethernet Accessory (ST-NIC) Network Interface Controller:

n Code 1, Internal Loopback - An internal loopback test is performed. n Code 2, External Loopback - Transmits packets to the cable in loop-back mode to check all transmit and receive paths and the cable itself. n Code #, Tests All - Performs both tests in sequence

Command 84 #: Request Accessory ID

Command 84 displays the boot version number. Command 84# displays accessory board ID. If no accessory is installed, the message "NOT AVAILABLE" is displayed.

Command 84#1#: Request Ethernet ID (MAC Address)

Displays the factory programmed Ethernet ID.

Command 120 #7: Request Accessory Audit/Stat Report

Produces a network/session statistics report for internal use only.

Troubleshooting the Installation

Important Facts about the Ethernet NIC

1 The NIC is 10BASE-T only. There are no 100BASE-T NICs avail-able.

2 If the NIC receives more than 120 broadcasts messages per second, the NIC will reset and the connection will be lost.

3 You cannot daisy-chain RS-485 clocks off of an Ethernet clock. 4 You may still be able to PING a clock that has a defective main

board.

5 The battery backup time for a clock with an Ethernet NIC and a lead acid battery backup unit installed is a maximum of six hours. 6 The NIC does not have a link status LED.

7 The host-PC-to-clock relationship is a master/slave relationship. The clock only communicates when information is requested by the host PC.

Troubleshooting Connectivity Problems

1 Make sure the link status LED is lit on both the NIC card and the port of the Ethernet device (hub or switch) that the clock is con-nected to. If it is not, check for loose connections.

2 If you can PING the clock, but cannot communicate with it from eTIME:

n Check for a duplicate IP address on the network by disconnect-ing the clock and pdisconnect-ingdisconnect-ing the IP address again. If there is a response, another device on the network is using the same address.

n If this is a replacement clock, get a new IP address (easiest approach), or update the ARP tables on network devices to reflect the MAC address of the new clock.

3 If you cannot PING the clock:

n Make sure that the NIC is seated correctly.

n Check the clock configuration and the eTIME configuration to ensure that the IP address is entered correctly.

n Make sure that the clock has the appropriate amount of memory installed.

n Try to PING the clock from another station. If you can, this may indicate a problem with the eTIME PC’s network connection. n Try to PING other network devices. If you cannot, there may be

a problem with the network itself. Contact the client network administrator.

4 If you cannot PING after one of the following events: n a new NIC was put in, and communications don't work

n the clock and the NIC have been replaced with new units, using the same IP address, but communications don't work.

Check to see if the polling PC is communicating to the clock through an Ethernet switch. If it is, it is possible that the switch has stored an association between the IP address of the original NIC of this timeclock and to the MAC address of the original NIC.

To correct this problem, the network administrator needs to: a) Get a new IP address for the clock.

b) Remove the entry from the switch database (ARP table).

c) Put a static entry in the switch database (ARP table) that correctly associates the clock’s MAC address with the assigned IP address.

5 If the clock is on a different segment than the eTIME PC and you cannot PING the clock, then move the clock to the same segment and retry the PING. If everything works, there could be a possible defective hub.

Troubleshooting Ethernet Performance

If performance of the clock is slow or sporadic (usually during an update cycle):

1 Consult the network administrator to find out times of day that the network is least busy. Perform polling and updates at least busy times.

2 Ask the client’s network adminstrator if it is possible to limit the number of broadcast packets that the clock has to process. Ways to do this:

n Increase the interval between broadcasts by network-connected devices (printers, for example).

n On a switched network, investigate whether it is possible to filter broadcast packets from the port that the clock is attached to. The clock does not process broadcast packets.

n If the client’s hubs or switches have the ability to filter traffic to a specific port, ask the client to filter all broadcasts (except ARPs) on the port the clock is connected to.
