Configure the Phasor Display tab by (Figure 2.65 on page 2-75), if applicable, by:

a. Clicking Add to add a new Phasor group on the Phasor Group tab.

b. Entering Header, Station name and ID names.

c. Using the down arrow to select a Baud rate and Period.

8. Click OK.

Peripherals Use this window (Figure 2.71) to set up the peripheral devices for the recorder. The actual items shown depend on the type of recorder and the options chosen at time of order.

There are six peripherals available:

• Modem - Sets up a modem-to-modem connection between the recorder and Display Station. If the modem is internal to the recorder the default port is COM 3. This leaves the rear port (COM 2) for DNP, serial time code or synchrophasor (TR2000).

• Fax - Sets-up a recorder to fax records on auto-call. This uses the fact that the data modem is also fax compatible. The fax output of a record is similar to the printed output from the recorder.

• Network - Shows the connection parameters of a recorder when it is connected over a network.

• Printer - Is only available if there is a printer selected on the configuration switches of the recorder.

• Distributed Network Protocol - Edit the parameters for a DNP connection, if embedded in the recorder firmware.

• Serial clock - Is only available when the recorder is configured for linking to an external serial clock. The clock is connected through the recorder's rear serial port. This option cannot be used at the same time as the DNP 3.0 option. This is also used for some IRIG-B systems. The addition of a PC 104 card or similar device allows a serial time interface in parallel with DNP or PMU.

Figure 2.71 Recorder Peripherals - Modem Tab Modem Tab Buttons and Fields

Modem String

Init String Click the check box and enter an initialization string for the modem. The character ^M translates to an ASCII carriage return and ~ translates to a half second delay (entered between commands).

The default initialization string, which is suitable for most modems, is:

AT&F^M~~~~ATS0=1^M

For US Robotics modems the initialization string is:

AT&F^M~~~~ATE1&B1C1&D2S0=2S7=120^M Dialing Prefix Click the check box and enter the string that

precedes the phone number. This is used to determine the type of dialing – tone or pulse. This normally is:

ATDT

Communications port

Baud rate Select the data rate for the recorder to talk to the modem. This should be greater than the connect speed of the modem: i.e. for a 33600 modem use a baud rate of 57600.

Inactivity timer Enter the length of time a recorder stays connected if no communications are occurring (range 2 – 30).

This limits costly long distance bills after inadvertently leaving a recorder connected.

Auto-call

Switch on and the recorder automatically calls the PC when a new fault is recorded.

NOTE Auto-call is via either modem or TCP/IP, not both.

Phone Number Enter the number to dial.

Auto-call parameters

Connect time Enter the amount of time a recorder waits for a call to be answered (range 3 – 300).

Retry pause Enter the length of time between the end of one dial attempt and the start of the next (range 0 – 999).

Retries Enter the number of times a recorder tries to connect to a PC before giving up (range 0 – 99).

DTR control Activate to drop DTR when the connection is inactive. This required for some modems.

Fax Tab Buttons and Fields

Auto fax Click either/both buttons to activate: Alarms and Records:

• Alarms sends internal alarms to the fax when

Fax options Use the drop downs to select display options for the target fax. They are not normally changed from the defaults.

Comms Options Use the drop downs to select the communications options between the recorder and the target fax.

These are not normally changed.

Connection Parameters

Attempt pause Enter the length of time to delay between each attempt at dialing the fax.

Attempts Enter the number of times to try re-dialing the fax before quitting.

Network Tab Buttons and Fields

Network Parameters

IP Address, IP Subnet Mask and Router IP Addr

Enter values in the fields to give the recorder a unique identity on the network. These parameters can only be changed when the recorder is

connected to the PC directly using the RS-232 port.

Auto-call

Auto-call Switch on and the recorder automatically calls, via TCP/IP, the PC when a new fault is recorded.

IP address Enter the address of the host PC. If this is used the Router IP Addr must also be entered. The host PC must have a fixed address. DCHP is not supported.

Auto-call connection parameters

Retry pause Enter the number of seconds a recorder waits after trying to connect to a PC before trying again (range 0 – 999).

Retries Enter the number of times the recorder attempts to connect to the PC (range 0 – 99).

Distributed Network Protocol Tab (DNP 3.0) Buttons and Fields

DNP Parameters

IED Address Set a number to identify the recorder on the network (range 1 – 65534).

Transmission delay Set the time to disable the master transmitter on an RS485 network (range 0 – 65535) (not currently used).

Data Link Confirm

Confirm mode Set as Never, Sometimes or Always. The default value is Never.

Retries Set the number of times the recorder retries to connect if Data Link confirmation is required (range 0 – 255).

Time-out Set the time the IED waits for a Data Link confirmation. Valid numbers are 0 – 65535.

Select/Operate arm time

Set the time period after the select command is received that the operate command is performed (range 0 – 65535) (Not currently used.)

Communications port

Enter the Baud rate of the recorder's rear serial port.

Printer Tab (TR100, TR100+ & TR2000) Buttons and Fields

Printer type Select a printer type from the drop down. This defines the escape sequences used by the recorder to set the output printer for graphics printing. The range of available printers includes dot matrix, ink jet and laser types. Most printers can be set to emulate the Epson FX80 or IBM Proprinter.

Auto print Select Auto print and the recorder prints all records and events as they occur. This can be switched off during set-up to disable records generated during testing from being printed.

Baud rate Select the baud rate for communication. IRIG-B defaults to 9600 baud.

Serial Format Select the appropriate data bits, parity and stop bits for communication with the clock. For NGTS 3.7.9 the default format is 7 data bits, 2 stop and even parity. IRIG-B defaults to 8 bits, 1 stop and no parity.
