Configuring the GPS Side of the MultiModem
1. Port Configuration
The GPS receiver module has two I/O ports. The table below provides the default protocols and port
configurations for the receiver, as delivered from the factory. TSIP IN/OUT is the default protocol on Port 1
and RTCM-IN and NMEA-OUT is the default protocol on Port 2.

GPS DB-9:
Pin 2 = Port 1 Transmit Data from GPS
Pin 3 = Port 1 Receive Data into GPS
Pin 6 = Port 2 Transmit Data from GPS
Pin 4 = Port 2 Receive Data into GPS
Pin 5 = GND
Pin 3 = Port 1 Receive Data into GPS
Pin 6 = Port 2 Transmit Data from GPS
Pin 4 = Port 2 Receive Data into GPS
Pin 5 = GND
Any standard serial communications program, such as Windows Hyper-Terminal or PROCOMM, can be
used to view the NMEA or TAIP output messages. TSIP is a binary protocol and outputs raw binary
serial data that cannot be read when using Windows Terminal or PROCOMM. To view the output of the
TSIP protocol in text format, use the iQ_CHAT or the iQ_Monitor program. These programs are
included on the CD-ROM as part of the MultiModem GPS Developer’s Kit.

iQ_Monitor
iQ_Monitor is used to verify GPS is functioning. The Developer Guide explains
how to setup and use this utility.
It is a 32-bit Windows application that interfaces with a TSIP-speaking receiver
through the GPS serial port. The program accepts TSIP reports and displays
these fields in a window:

iQ_Chat
iQ_Chat is a 16-bit DOS-based application that interfaces with the GPS receiver
through a serial port. It allows you to exercise TSIP commands, configure the
GPS receiver for NMEA or TAIP, and view NMEA or TAIP output. It also logs a
TSIP report in binary format.
