P4: Serial Port and Programmable Output (DB9 Connector)

Do NOT over-tighten the securing screws of the connector!
The following signals are present on P4 (DCE configuration only):
 Pin 1: RS232 level (-9V to +9V) programmable output.
 Pin 2: RS232 level serial string.
 Pin 5: RS232 signal ground.
 Pin 4 & Pin 6: RS422 level 5V) differential programmable output.
 Pin 8 & Pin 9: RS422 level serial string.
The RS232/RS422 signal lines are not isolated from each other, but the port as a whole has an
isolation rating of 2.5 kV from all other ports.

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 user configurable data rate between 1200 and 38400 bps
(available rates are 1200, 2400, 4800, 9600, 19200 and 38400 bps). Message formats typically
operate at 9600 baud, 8-bit with no parity, no flow control and 1 stop bit. Most messages are
transmitted once per second.
A wide range of message strings and protocols can be output on this port. They include:
 NTS protocol (transmits once per minute)
 IRIG J-17
 Seven pre-set messages, String/Tekron A G for compatibility with most IED.
 NMEA ZDA and RMC messages
 GNSS Binary/Messages, these are subject to change without notice.
See Appendix (SERIAL OUTPUT STRINGS) for details on each of the message string formats.
A common application for the programmable output on P4-pin 1 (RS232 level) is to provide an
independent drive to an RS232-Fiber converter unit for use in transporting time-code/pulse signals
to a distant location. (Tekron manufactures a range of interface devices (ITRs) that include such
converters.
connect to an external PC, and used in conjunction with pin 5 (signal return).

P4-pin 1 Programmable Output

The user may configure the P4-pin 1 output to operate with inverted or non-inverted polarity, and:
 A user-configurable number of pulses per second, minute, hour, day with adjustable
pulse-width and offset.
 IRIG-B and DCF-77 time codes.

If not requested otherwise, the TCG 01-G is normally shipped as a DCE
can be used to connect directly to a standard PC serial port. A suitable 2 m
cable is included with each TCG 01-G purchase. The CTS and DSR lines are
permanently asserted. As the serial outputs are usually precisely timed
messages, there is no provision for either hardware or software flow control.
