Time Code Option (AM or DC)
The Time Code Option can be either amplitude-modulated (AM) or DC-shift (DC) output. For ex-
ample, these may be labeled: “A-AMCODE” (AM Time Code on connector A) or
“C-DCCODE” (DC Time Code on connector C).
Time Code is a “system signal”. This means that there is one Time Code signal that affects the whole
system. In other words, if your RTM3205 has multiple Time Code outputs (AM and/or DC) and you
change the Time Code format, then all Time Code outputs will be affected.
The Time Code format is normally IRIG-B122 (AM) or B002 (DC) when shipped from the factory
but can be changed (see below). For details on signal definition see
Appendix K - Specifications,
AM Code Output
or
Appendix K - Specifications, Optional DC Code Output
.
View the Time Code Connector
The
cpuio
command will list any connector on the RTM3205 that has an I/O signal. Connectors are
identified as A, B, C or D.
Command:
cpuio
RTM3205 reply:
CPU I/O A - AM TIME CODE OUTPUT is Installed
Current Setting = (See systemio command)
Change the Time Code Format
Use the
systemio
command to view the time code format. Use the
systemioconfig
command to
channge the format.
Command:
systemio
RTM3205 reply:
System I/O Signal TIME CODE OUTPUT is Installed
Current Setting = IRIG-B122/B002 Format
Command:
systemioconfig
RTM3205 reply: Interactive script is started so you can change the Time Code format.
Programmable Pulse Output (PPO) Option
The PPO Option provides user-selectable, on-time pulse rates from 1 PPS to 10 MPPS. Other selec-
tions are 1PP60S (pulse per 60 seconds, on the minute), 1PP2S (pulse per 2 seconds, on the even
second), and Inverted 1 PPS (falling edge on-time). For details on signal definition see
Appendix K
- Specifications, Optional Programmable Pulse Output
.
View and Change the PPO
The
cpuio
command will list any connector on the RTM3205 that has an I/O signal. Connectors
are identified as A, B, C or D. The
cpuioconfig
command will allow you to change the pulse rate
selection.
