TSIP packets recognized by ArcPad

The Trimble Standard Interface Protocol (TSIP) is a Trimble proprietary protocol for communicating with Trimble GPS receivers and some GPS receivers which use Trimble GPS boards.

The TSIP protocol consists of a number of binary packets which are used to request and receive information from the GPS receiver. Many TSIP packets are not sent by the GPS receiver unless specifically requested to do so via the receipt of a request TSIP packet. In contrast, most NMEA sentences are automatically sent by the GPS receiver once the receiver has been configured to output the NMEA 0183 sentence.
