3. Calixto CST-GL86x-MODEM ordering Info
3.1 Product Variants
There are two variants of the module available:
• Standard modem with Telit GL868 DUAL module: CST-GL868-MODEM
• CST-GL868-MODEM with battery harging interfa e: CST-GL868-MODEM-BC
Note: There is option for ustomers to order GL865 QUAD version of the modem. But, minimum order
quantity in this ase will be 100.
4. Product details
The figures below shows pi tures of CST-GL868-MODEM-BC with important omponents marked. SIM ard
holder is in the other side of the board as in se ond pi ture .

5. Hardware Description
5.1 Telit GL86x module:
This modem implements all the fun tionalities in luding Digital/Analog out using Telit’s GL86x series of
GSM/GPRS module. Default version of the module is GL868 DUAL. For orders more than 100 lots, ustomers
have opportunity to order different versions of GL86x modules. This do ument is not in luding any details of
GL86x module. Customer an get more information from Telit web site for more information.

5.2 GPRS Antenna
Antenna onne tor allows transmission of radio frequen y (RF) signals between the modem and an external
ustomer-supplied antenna. Calixto provides option one of the two antenna onne tor options. One is uFL
and other one is 5050ΩFME male oaxial ja k. As an option Calixto provides WIP Antenna with 50ΩFME male
oaxial ja k onne tor.

5.3 Power Jac
The power Ja k supported is 2mm DC power ja k with lo king option. The figure below shows the power ja k
used in the modem.
5.4 LED Indications
There are two LEDs in the CST-GL868-MODEM. LED1 (at D1) is power LED and LED2 (at D6) is GPRS status LED.
For CST-GL868-MODEM-BC, there is an additional Charging Indi ator LED (D2).
5.5 Battery connector
CST-GL868-MODEM-BC modem has additional battery onne tor. This is a 2 pin Relimate onne tor (lo ation
B1).
5.6 RS232-DB9 (J2)
This DB9 onne tor has main UART of the GSM/GPRS module in RS232 level.
