1 When performing a quick
test of the MPRX, the buzz
box does not buzz. Check all your wiring connections and antenna connections and
ensure that your buzz box is functioning.
The wires from the MPRX are grouped in pairs. You could find more
than one red wire, more than one black wire, and so on. You must
connect the correct red and white wire pair to the leads from the
battery.
Verify that RF is on. Using a terminal emulation program, you may
switch to command mode and issue command
#527
to determine
RF status. Refer to page 7-18 for more information.
2 The baud rate is selected
correctly but nothing
happens. The MPRX is not communicating with your host device. Check the
power supply to your host device, and check the connections
between the host device and the MPRX. Try reversing the receive
and transmit connections. Also, check the position of the Interface
Selection Switch.
