CTP2000 8P-IRIG Interface Module
The CTP2000 8P-IRIG interface module enables an interrange instrumentation group time code (IRIG-B)
signal to be transported through an IP network. IRIG-B is a special time code transmission format that uses
a hybrid analog/digital physical interface. The IRIG-B standard consists of a family of rate-scaled serial
time codes with formats containing up to three coded expressions or words. The IRIG-B pulse code contains
one frame of 100 elements per second for the time of the year and GPS receiver status. IRIG-B encodes
day of year, hour, minute, and second data on a 1-KHz carrier frequency, with an update rate of once per
second.
The CTP2000 8P-IRIG module has eight ports. You can configure direction, high and low level output, and
data range for this module. (See
.)
NOTE:
CTP2000 8P-IRIG Interface Module can no longer be purchased.
