There are 3VDC and 5VDC GPS antenna in the market. For connecting the GPS antenna to the cnMatrix TX2K tower switch, may I know the DC power coming out from the antenna interface on the switch?
I don’t know the voltage, but I do know it works with any ePMP GPS puck. That’s what we use and it works very well.
I just wonder if it is necessary to use or purchase the GPS puck of ePMP for connection to the cnMatrix for sync purpose.
Actually, there are a lot of suppliers in the market to supply GPS antenna, e.g. Trimble. If customer already has GPS antenna on hand, it will help them to save cost as long as the operating voltage of the GPS antenna is same as the GPS voltage output from the cnMatrix.
