5.3.2 P2, P2 programmable signals
The user may configure P2 and P2 to output in either inverted or non-inverted polarity:
x
A user configurable number of pulses per second, minute, hour, day with
adjustable pulse-width and offset.
x
IRIG-B and DCF-77 time codes.
Refer to page 13 for further information:

P4: RS232 I/O (Serial port plus programmable output)
An RS232 port (+/-9V signal levels) is implemented via 9-way “D”
male connector with signal lines: p
pin 2 (serial data OUT from TCG
01), p
pin 3 (serial data IN to TCG 01) and p
pin 5 (signal ground)
together with a programmable signal output on p
pin 1. The
programmable output shares the p
pin 5 (signal ground).
Do NOT over-tighten the securing screws of the connector!
TCG 01 is normally shipped as a DCE configuration, a “straight-wired” Socket-to-Socket
9-way data cable can be used to connect directly to a standard PC serial port. (A suitable
2m cable is included with each TCG 01/TCG 01F.) The CTS and DSR functions are
permanently asserted, so the serial port does not support hardware handshake control.
The RS232 signal lines are not HV-isolated from each other, but the port as a whole is
isolated to a level of 2.5kV from all other ports.
5.4.1 P4 serial strings
The serial port can be configured to output any one of a number of different serial time
messages on a broadcast basis. The serial port runs at a fixed baud-rate of 9600 baud.
Message formats typically operate at 8-bit no parity, no flow control, 1 stop bit, and are
transmitted once per second.
A wide range of message strings, and protocols are output on this port. They include:
x
NGTS protocol
x
IRIG J-17
x
Six preset messages, String/Tekron A—F for compatibility with most IED.
x
In TCG 01 version D8 and later, NMEA ZDA and RMC messages are available.
x
GPS Binary/Messages, these are subject to change without notice.
