Oscillography - GE LPS-O Instruction Manual

2.2 GENERAL SETTINGS
203: COMPORT3 - Communications Port 3
COMPORT3 sets the baud rate, parity, and stop bits of RS232 serial port 3. The setting format is ixxyz where:
interface = i
Baud Rate = xx
Parity = y
2
Stop Bits = z
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.
204: PROTOCOL1 - Communication Port No. 1 Protocol
Two settings are possible:
1. GE-MODEM. Use this setting to communicate with the LPS-O system via the LPSO-Link communications
program as described in Chapter 11: LPSO-LINK USER GUIDE.
2. ASCII. Use this setting to communication with the LPS-O system via the ASCII commands provided in
Chapter 12: ASCII COMMUNICATIONS.
205: PROTOCOL2 - Communication Port No. 2 Protocol
Two settings are possible:
1. GE-MODEM. Use this setting to communicate with the LPS-O system via the LPSO-Link communications
program.
2. ASCII. Use this setting to communicate with the LPS-O system via the ASCII commands provided in Chap-
ter 12: ASCII COMMUNICATIONS .
206: PROTOCOL3 - Communication Port No. 3 Protocol
Two settings are possible:
1. GE-MODEM. Use this setting to communicate with the LPS-O system via the LPSO-Link communications
program.
2. ASCII. Use this setting to communication with the LPS-O system via the ASCII commands provided in
Chapter 12: ASCII COMMUNICATIONS .
301: NUMFAULTS - Number Of Faults To Be Captured
NUMFAULTS selects the maximum number of oscillography storage events (faults) that may be stored in
memory. When the maximum number are stored in memory, the oscillography data associated with a subse-
quent storage event will overwrite the data from the oldest event.
This setting allows the user to apportion a fixed amount of memory into different sized blocks for oscillography
storage. Table 2–3: OSCILLOGRAPHY CYCLES PER STORAGE EVENT shows the total number of oscillog-
raphy cycles allowed per storage event as a function of the NUMFAULTS setting.
