CGK-5x DESCRIPTION
2. Description of the CGK-5x
2.1. General description
The CGK-5x is application which contain programmable GSM/GPRS mo ule Cinterion.
The CGK-5x mo ule is fitte with a Java-base control software which is use to ata or
RS232 serial port maintaining, control two output ports with relays an four optically separate
input ports. To this evice can be connecte 12 V lea backup battery.
Configuration of the CGK-5x mo ule can be carrie out through the RS-232 serial
interface by means of the GSM key ADMIN [1] or RADWIN [2] service program.
2.2. Examples of using
• GSM key – gates, motors or barrier controlling by mobile
• Alarms SMS etector from connecte inputs (sensors)
• Technology remote control
• GPRS ata transmition from in ustry, measurements an security evices
• GSM/GPRS terminal
2.3. escription of the individual parts of the CGK-5x
2.3.1 Programmable GSM-GPRS module
Wireless communication in the GSM network is carrie out by means of the OEM
mo ule TC65i-X Java of the Cinterion company. It has been incorporate irectly in the
printe -circuit boar . The push-out hol er of the SIM car rea er is accessible from the front
panel. The antenna connector is accessible from the rear panel. The TC65i-X mo ule is
suitable for communication in both GSM ban s 850/900/1800/1900 MHz.
The TC65i-X mo ule is fitte with two serial interfaces, ASC0 an ASC1. The ASC1
interface has been brought out to the RJ45 connector, which is labelle COM. All the RS232
signals are protecte against the over voltage coming through the ata cable.
The mo ule TC65i-X contain interface USB2.0 full spee too, which is take out on USB
connector of type 'B' un er marking USB. For this interface it is elivere river. The USB
interface is not exploite by Java application.
2.3.2 Control microcontroller
The CGK-5x communication mo ule has been fitte with an 16-bit microcontroller that
serves for starting an monitoring the TC65i-X mo ule operation. The operating microcontroller
is also use for monitoring the state of the supply voltage (see section 2.8 Power supply).
2.3.3 Inputs and outputs
Besi es the service ata an USB interface, an IO interface has been create
in the CGK-5x mo ule. This is a case of two pairs of signals, where two pairs represent the
relay outputs (O1A+O1B an O2A+O2B), an four represent the separate inputs (I1, I2, I3,
I4) with common groun . The input I1 is possible use as counter input for counting with max.
frequency 100 Hz an pulse ratio 10 to 50 %. Inputs an output circuits have been esigne
for voltage up to 30 V.
