DC Power Input Jack
This 2-position jack provides connection to the DC power source. See
details in
Appendix F - Specifications.
10/100Base-T Jack
This rear-panel RJ-45 connector mates with the ethernet twisted pair
cable from the network.
Performing an
Initial Site Survey
Using the status LED indicators, it’s easy to find out if your RTM3204 will work in your desired loca-
tion:
1. Mount the antenna on the roof using the supplied mounting hardware. Make sure that it is not
blocked by large metallic objects closer than one meter.
2. Connect the BNC plug on the end of the antenna cable to the supplied BNC jack to SMB plug
adapter cable. Connect the SMB plug end of the adapter cable to the antenna input jack on the
RTM3204 GPS Timing Module.
3. Connect the “+24VDC” terminal to the positive output of the DC power source. Connect the
“GND” terminal to the negative output of the DC power source. The DC power source voltage must
not 32V. This unit will not operate if the +/- connections are reversed; however it will not be
damaged by a reverse connection. Note that the GND terminal is connected to the chassis inside the
unit.
Initially upon power up:
1. The unit will light the red Alarm Status LED for about ten seconds.
2. Then it will continuously light the green Sync Status LED.
3. Since your unit has a Rubidium oscillator (Rb), it will need 5 minutes to warmup before trying to
acquire a signal. When the unit locks onto a GPS signal and begins to decode the timing data and
adjust the local oscillator, the green Sync Status LED will flash very rapidly (about a 6 Hz rate) until
the data is fully decoded and the local oscillator is fully locked to the GPS frequency.
