6. Troubleshooting the GL7x00

This section of the document describes possible problems that might be encountered when using the
GL7x00, and their corresponding solutions.

To read about other troubleshooting information, refer to the

Sierra Wireless Source

6.1.

No Communications with the GL7x00 through
the Serial Link

If the GL7x00 does not answer to AT commands through the serial link, refer to the table below for
possible causes and their corresponding solutions.

Table 22.

Solutions for No Connection with the GL7x00 through the Serial Link

If the GL7x00
returns

Then ask

Action

Nothing

Is the GL7x00 powered correctly?

Make sure that the external power supply
is connected to the GL7x00 and provides
a voltage within the range of 4.75V to
32V.

Is the serial cable connected at both sides?

Check the serial cable connection.

Does the serial cable correctly follow the pin
assignments as shown in section 2.2.1 8-pin
Micro-Fit Connector?

Connect the cable by following the pin
assignments as given in section 2.2.1 8-
pin Micro-Fit Connector.

Nothing or non-
significant characters

Is the communication program properly
configured on the PC?

Ensure that the settings of the
communication program are compatible
with the settings of the GL7x00.

The GL7x00 factory settings are:

•

Data bits = 8

•

Parity = none

•

Stop bits = 1

•

Baud = 115200 bps

•

Flow control = hardware

Is there another program interfering with the
communication program (i.e. conflict on
communication port access)?

Close the interfering program.
