Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.

This section describes the different connectors, interfaces and peripherals that connect with the
modem.
The modem is distributed in the market as a finished product with the following interfaces:
an 8-pin Micro-Fit Connector
an FME RF Connector
a Flash LED Indicator
a SIM Connector
The interface signals available from the modem are listed in the following table. For more information
about these signals, refer to the corresponding chapters.
Table 3. Available Interface Signals
2.1. Front Interface
Figure 4. GL8200 Front View
2.1.1. SIM Interface
The Subscriber Identification Module can be directly inserted in the modem through the SIM door.
The SIM interface controls both 1.8V and 3V SIM cards and it is fully compliant with GSM 11.11
recommendations concerning SIM functions.
The SIM interface is ESD protected. Transient Voltage Suppressor diodes are internally added on the
signals connected to the SIM interface in order to prevent any damage from electrostatic discharge.

2.1.2. Flash LED
The GL8200 has an LED indicator to show the status of the GSM network.
Table 5. LED Status
The Flash LED can be
deactivated by the AT command AT+KSYNC=0
activated by the AT command AT+KSYNC=2,4
For more information about AT commands applicable to the GL8200, please refer to the commands
marked as supported by HL8548x in document [2] AirPrime HL6 and HL8 Series AT Commands

User Guide
2.2.1.1. Power Supply
The GL8200 is supplied by an external DC voltage (VIN-VBUS) that ranges from 4.75V to 32V at
2.2A. This input is available on the modem from the 8-pin Micro-Fit connector.
Table 7. Input Power Supply Voltage
Note that the correct operation of the GL8200 in communication mode is not guaranteed if input
voltage (VIN-VBUS) falls below 4.75V.
The following table describes the consequences of having the GL8200 go either over or under the
specified voltage range.
Table 8. Effects of Power Supply Overload/Underload
Note: The minimum input voltage specified here is the GL8200 input. Be mindful of the input voltage
decrease caused by the power cable. When using the cable that comes with the GL8200, this input
drop is at around 800mV at 4.75V and 220mV at 32V.
The power supply must withstand a current peak of 2.8A in 4.75V input voltage. Refer to Table 21
Power Consumption (Typical Values) for more current information.
2.2.1.2. Serial Link (RS232)
The modem’s serial link, RS232, performs the voltage level adaptation (V24/CMOS) between the
GL8200 (DCE) and external applications (DTE).
The RS232 interface is internally protected against electrostatic surges on its lines by ESD protection.
The RS232 interface has the following filtering guarantees:
EMI/RFI protection on both the input and the output
Signal smoothing
Signals available on the RS232 serial link are as follows:
TX data (RS232-TXD)
RX data (RS232-RXD)
Request To Send (RS232-RTS)
Clear To Send (RS232-CTS)
Data Terminal Ready (RS232-DTR)
