The Terminus Wireless Terminal is a versatile communications device that can be used in many remote monitoring and
control applications including alarm control, location monitoring and remote computer access. The Terminus GSM864Q
Development Kit provides everything you need to get started creating custom applications using the included Python
tools. The GSM864Q-BB Breakout Board included in this kit provides easy access to all of the available I/O of the
Terminus, as well as, serial ports for the Telit and GPS modules. This guide will help you quickly set up and use your

Wall Transformer type 12 VDC, 2A power supply • Documentation CD
•
What you need
A computer with an RS-232 Serial interface
•
A SIM card with a valid network subscription
•
Connecting
Note: Perform these steps in order as listed. Always use an ESD wrist strap when handling ESD sensitive devices!
Jumpers – Jumpers P7 and P8 enable the RS-232 line drivers for the AT Command and GPS CMOS UART interface. If
the serial interface at the screw terminals is being used, these jumpers should NOT be used.
Jumper P7: Serial 1, AT Command – If communicating with the Terminus via the 50-PIN header CMOS UART
•
interface, the user will need to place a shunt across Jumper P7. This will enable the RS-232 line driver and allow
connection to a PC. If the 50-pin header CMOS UART is needed, the UART_SEL pin needs to be set to Logic “0”
or Ground.
If user is executing a Python script to control the application, the Python script should set GPIO 20 to logic zero
to send UART data out via the 50-PIN CMOS UART interface. The UART_SEL pin should not be externally driven
once GPIO 20 is configured as an output.
Jumper P8: Serial 2, GPS – To monitor the GPS NMEA data stream via the RS-232 line driver on connector P6

SIM Card
Insert SIM card into the SIM cardholder under the top cover on the Terminus as shown
•
Antennas
Connect the GSM antenna to the SMA jack on the Terminus.
•
Connect the GPS antenna to the MCX jack. Make sure that a clear sky view is available for best GPS reception.
•
Audio Devices
Connect the handset to the 4P4C modular audio jack on the Terminus
