2 CALCULATION OF SETTINGS 2.2 GENERAL SETTINGS
2
As an example, if you are using an LPS-O and outputs T1 and T3 are to be monitored and T2 and T4 are not,
the following setting would be used:
NUM_MON
= 0101
This setting is entered in to the relay from the LUI in decimal format (that is,
NUM_MON
= 5).
108: DISPLAYVAL - Present Value Display Mode
This setting determines the mode in which the system values (
I , V , etc.) are displayed. Two settings are possi-
ble: PRI displays the values in primary quantities, whereas SEC allows secondary values to be displayed.
109: LANGUAGE
Two settings are possible: ENGLISH or SPANISH.
2.2.2 COMMUNICATIONS
201: COMPORT1 - Communications Port 1
COMPORT1
sets the baud rate, parity, and stop bits of RS232 serial port 1. The setting format is
xxyz
where:
Baud Rate =
xx
= 03, 12, 24, 48, 96, 19
Parity =
y
= 0 (none), 1 (odd), 2 (even)
Stop Bits =
z
= 1, 2
The baud rate setting of 300, 1200, 2400, 4800, 9600, or 19200 must be set to match the baud rate of the
modem or serial device connected to the serial port of the LPS-O relay system. The parity and stop bits must
match those selected for the serial port of the remote PC. Normally 1 stop bit is selected. However, certain
modems or other communications hardware may require 2 stop bits. LPSO-Link communications software can
be configured to match this LPS-O setting for baud rate, parity, and stop bits.
202: COMPORT2 - Communications Port 2
COMPORT2
sets the baud rate, parity, and stop bits of serial port 2. The setting format is
ixxyz
where:
interface =
i
= 0 (RS232), 1 (RS485)
Baud Rate =
xx
= 03, 12, 24, 48, 96, 19
Parity =
y
= 0 (none), 1 (odd), 2 (even)
Stop Bits =
z
= 1, 2
The baud rate setting of 300, 1200, 2400, 4800, 9600, or 19200 must be set to match the baud rate of the
modem or serial device connected to the serial port of the LPS-O relay system. The parity and stop bits must
match those selected for the serial port of the remote PC. Normally 1 stop bit is selected. However, certain
modems or other communications hardware may require 2 stop bits. LPSO-Link communications software can
be configured to match this LPS-O setting for baud rate, parity, and stop bits.
