MX800 Transceiver Options
Method:
1. Remove the cover to the MX800 radio.
2. Remove the motherboard from the chassis.
3. Remove the Exciter and receiver modules from the chassis by unscrewing
the 2 M4x35mm screws on each module.
4. Remove the existing front panel from the chassis by unscrewing the qty4
screws securing the handles to the front panel – Do not discard the
screws.
5. Place the upgrade front panel on the front of the chassis and secure with
the matching handles and the previously removed screws. Ensure that the
front panel holes are aligned with the corresponding chassis holes and
fully tightened handle screws.
6. Install the local channel change switches into the front panel hole and
secure into position hot melt glue.
7. Route the switch Assy cable along the front of the chassis and to the rear
of the motherboard standoff posts closest to the front of the chassis.
Secure into position with a small piece of tape.
8. Re-install the exciter and receiver modules into the chassis.
9. Re-install the motherboard into the chassis being careful to align the front
panel hole positions with the corresponding motherboard components.
10. Re-connect all of the modules and chassis mounted connectors/switches
to the motherboard via their appropriate cable assembly’s.
MX800 Controller Setup:
1. The Local Channel Change option is activated in the MXTOOLS
‘Configuration’ heading, within the ‘Software’ folder with ‘Channel
Select Input’ selection of ‘BCD’.
2. Download the configuration change to the MX800.
MX800 Testing:
1. Connect a Communications Test Set and the RIB to the MX800.
2. Set the switches on the RIB to Line
Audio and Line E&M.
3. Set MXTOOLS into Diagnostics mode and ‘Start’ the diagnosis process.
4. Change the channel on the local channel switches and check that the
channel selected on the BCD switch is in fact the channel that the
Diagnostics screen indicates.
5. Reset the MX800 operating channel to the required position.
