3.2 Physical Dimensions and Weight
Overall dimensions: 77 x 67 x 26 mm
Weight: approx. 100g

Electrical Description INSYS GPRS mini
4Electrical Description
The modem uses the following standard connectors:
RJ11 6-way (power connector)
Mini USB (USB 2.0)
SIM card reader
FME male coaxial jack (antenna connector)
Sub-D female socket, 9 pin (RS232 serial port)
4.1 Power Connector
An RJ11 6-way connector, as shown and described below, serves as a
means of supplying and controlling DC power to the modem. It is necessary
to connect an external power supply, since the available power on the USB
port is not sufficient to run the modem.
The supply voltage, VCC, required by the modem is 5V - 32V DC. Application
of the supply voltage does not switch the modem on. To do so an additional
active-high control signal, TO_IN, must be applied for > 1 second.
Please see chapter “Switching ON the modem” for further important details
about TO_IN and power supply requirements, especially if TO_IN is applied in
parallel to VCC.
VCC and GND are reverse-polarity and over-voltage protected.
Note: This does not apply for the GND on the antenna connector if
this coax GND / shield are connected to your applications
ground-plane.

INSYS GPRS mini Electrical Description
4.4 RS232 Serial Port
The modem supports a standard RS232 serial interface via its 9 pin Sub-D
connector, shown below. In line with serial communication terminology the
INSYS GPRS mini should be considered as the data circuit-terminating
equipment (DCE) and the external application or computer as the data termi-
nating equipment (DTE). The maximum baud rate to communicate with the
INSYS GPRS mini is 230400 kbit/s.
The electrical characteristics of the serial port signals are shown below:
PIN Signal Direction Voltage levels Description
1DCD Output > + 4V
<- 4 V Data carrier detect
2RD Output > + 4V
<- 4 V Received data
3TD Input > + 2,4V
< 0.8 V Transmitted data
4DTR Input > + 4V
< 0.8 V Data terminal ready
5GND -0 V Ground connection
6DSR Output > + 4V
< - 4 V Data set ready
7RTS Input > + 2,4V
< 0.8 V Request to send
8CTS Output > + 4V
< - 4 V Clear to send
9RI Output > + 4V
< - 4 V Ring indicator
4.5 Serial Data
The modem supports the standard data character format of
Programmable baud rate (300bps to 230,400bps).
Auto-configuration mode with auto-baud (1,200bps to 230,400bps).
Multiplex ability according to GSM 07.10 Multiplexer Protocol.

Electrical Description INSYS GPRS mini
4.6 Serial Data Signals
Serial Data From Modem (RD)
RD is an output signal that the modem uses to send data to the application.
Serial Data To Modem (TD)
TD is an input signal, used by the application to send data to the modem.
4.7 Control Signals – RTS, CTS, DTR, DSR, DCD, RI
Request to Send (RTS)
RTS is used to condition the DCE for data transmission. The default level is
high by internal pull up. The exact behaviour of RTS is defined by an AT
command. Software or Hardware control can be selected. Hardware flow is
the default control. The application must pull RTS low to communicate with
the modem. The modem will respond by asserting CTS low, indicating it is
ready for communication.
Clear To Send (CTS)
CTS indicate that the DCE is ready to transmit data. The default level is high.
You can define the exact behaviour of CTS through an AT command, and
can select software or hardware flow control.
Data Terminal Ready (DTR)
DTR indicates that the DTE is ready to transmit and receive data. It also acts
as hardware ‘hang-up’, terminating calls when switched high. The signal is
active low. You can define the exact behaviour of DTR with an AT command.
The DTR line can also be used to switch on the modem when activated for
0.2 seconds. The DTR line must be deactivated prior to switching off the
modem to ensure it switches off (powers down) correctly.
Data Set Ready (DSR)
An active DSR signal is sent from the modem to the application (DTE) to con-
firm that a communications path has been established. DSR has two modes
of operation, settable using the AT command AT&S.
Data Carrier Detect (DCD)
DCD indicates that the DCE is receiving a valid carrier (data signal) when
low. You can define the exact behaviour of DCD with an AT command.
Ring Indicator (RI)
RI indicates that a ringing signal is being received by the DCE when low. You
can define the exact behaviour for RI with an AT command.
