12.9 Operation
Once the module has been mounted to the developer's board
and all connections are made you are ready to power up the
developer's board. Refer to Mounting a GX-47/48, page 66 for
mounting information and a connection diagram.
Power On
To Power on the unit, ensure a 12VDC supply is connected to
J101 and toggle the power switch S102. CR101 upper should
illuminate. Press S400 and hold down for at least 0.5 seconds.
CR103 upper should illuminate then about 4 seconds later
CR103 lower will illuminate and a random character should
appear in your terminal program (if connected to Serial port 1
and port settings are correct). Refer to GX-47/48 Family;
Connection, page 67.
12.10 Flow Control
The developer's board has the ability to disable and enable the
routing of HW flow control signals between the PC and the
module. This is accomplished by setting S501 as per section
14.3.
Whenever communications difficulties arise with the module,
disable HW flow control both on the developer's board and in
your terminal program as a first step.
12.11 Power Down
When shutting down the developer's board and/or module it is
important that the module is allowed to perform and orderly
shutdown before power is removed. Do NOT simply pull the
plug. Press S400 (the hardware shutdown button) and hold
down for at least 1.5 seconds. Or send AT+CFUN=0. The radio
device takes a few seconds to shut down properly. CR103
upper will stay illuminated until shutdown is complete.
