2. Overview
2.1 General
GNAD1A is a proprietary GSM/GPRS/EDGE module from Continental Automotive Systems.
The module will be integrated into telecommunication control devices produced by Continental
for its automotive customers.
The GAND1A test set-up is available for third-party testing which do not require audio or data-
logging capabilities. This document will provide description for the test set-up.
2.2 GNAD1A Description
GNAD1A is a proprietary GSM module designed and manufactured by Continental Automotive
Systems for use in automotive applications. The key features of the modules are:
• Quad-band GSM/GPRS/EDGE
• GPRS and EDGE Class 10
• 5 V DC Input
• 250-450 mA average current draw while in a call
• Up to 3 A peak current during GSM burst
• Fakra RF connectors
• Primary (black) and Secondary (maroon) RF antenna connectors
• On-board SIM card connector for 3 V SIM cards
• 40-pin system-level connector
• PCM audio
• Primary UART with auto baud rate detection up to 115.2 Kbps. Max supported rate is
921.6 Kbps.
A diagram of the GNAD1A GSM module is shown in Figure 1. A photograph of the GNAD1A
module is shown in Figure 2.

2.4 Quick Start Communication Guide
In order to communicate from a laptop to the GNAD1A (as shown in Figure 3), the
following equipment is needed:
Laptop PC
Interface board
5V DC Power supply (2 Amp)
GNAD1A
Serial Port Cable
HyperTerminal, Hyper Access or another Communication tool For use with
HyperTerminal baud rate needs to be set to 57.6Kbits, 8 bits, no parity, no stop bits,
and hardware flow control.
The following procedure should be followed to communicate with the GNAD1A:
1) Set the power supply to 5.0V and the current limit to 2.0A.
2) Connect the interface board to the power supply
3) Connect the serial port cable to the COM1 of PC and to the RS-232 connection on
the Interface board.
4) Turn on the power supply output.
5) Press the NAD_ON_OFF switch for 3 seconds. The module should power on.
6) Use the primary UART to communicate with the NAD using HyperTerminal,
Hyperaccess etc. “READY” message will appear when module powers on.
7) To turn the NAD off, press and hold the NAD_ON_OFF switch again for 2 seconds.
2.5 Quick Start Call Guide
After setting up the interface board and GNAD1A as discussed in 2.4, the following AT
commands can be sent to the NAD using HyperTerminal to make a call:
1) Type AT to confirm communication should receive OK back.(optional)

2) The module is pre-set to use primary (black) antenna. Type AT+TASW= 1
(primary) or AT+TASW=2 (secondary) for antenna selection.
3) The radio will start scanning automatically on power-up with an unlocked SIM.
4) Type AT+XBANDSEL=NUM (where NUM is 850, 900, 1800, 1900 or 0 for all
bands) to set the band of operation if desired (optional).
5) Type ATD123456; to make a voice call.
6) To end the call type ATH
Data calls are not discussed here but standard AT commands apply.
2.6 List of Supported AT commands for testing purposes
The section lists AT commands supported by GNAD1A. Unless otherwise noted, the AT
commands shall follow the syntaxes specified in GSM 07.07. See AT Command manual for

2.7 FCC Note
This device complies with Part 15 of the FCC Rules. The FCC ID for this device is
LHJGNAD1A. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications to this system by other than an authorized service facility could void
authorization to use this equipment.
Please note that if the GNAD1A module is integrated into a host device, second label must be

LHJGNAD1A".
The GNAD1A module is offered for use with an external antenna which is not specified by
Continental Automotive Systems. The intended use-case for the device is with a vehicle roof-top
antenna. The antenna(s) which are used for the transmitter must be installed to provide a
separation distance of at least 20cm from all persons and must not be co-located or operating in

conjunction with any other antenna or transmitter. The following are the guidelines for the
maximum antenna gain which should be used for selecting an external antenna:
• For the 850 MHz band the maximum antenna gain is -1.24 dBd
• For the 1900 MHz band the maximum antenna gain is 7.8 dBi
The maximum gain of the antenna path (cable loss + antenna gain) shall not exceed the above
mentioned values.
