Technical Manual Options
5. Install the Option PCB onto the 4 standoffs with the 16way connector
closest to DIP2 on the Motherboard. Secure with the qty4 3x5mm
machine screws previously removed.
6. Install the 16way-ribbon cable between connector SKK on the
Motherboard and SKK on the Option board, taking note that the cable is
correctly orientated.
7. Check that the option board jumpers are in the following positions;
1. JMP1 IN
2. JMP2 IN
3. JMP3 OFF
4. JMP4 ON
MX800 Controller Setup:
1. The VF Delay option is activated in the MXTOOLS ‘Configuration’
heading. Within the ‘Hardware’ folder select ‘Delayed Audio Option’.
2. Download the Configuration change to the MX800.
MX800 Testing:
1. Connect a Communications Test Set via the RIB to the MX800.
2. Set the switches on the RIB to Line Audio and E&M.
3. Set the test set to measure Rx line level and ensure that the Receiver is
operating correctly.
4. Whilst listening to the RX audio output, switch the RF output on the
Comm.'s test set on and off and note that there is NO distinctive ‘Click’
in the audio when the RF is switched OFF.
5. Replace the MX800 cover.
3.7 T09 300Hz Upgrade HPF Filter
3.7.1 Description
This option provides upgraded CTCSS tone suppression on the RX VF.
When this option is fitted the standard 300Hz filter is removed from circuit
by changing the position of JMP5 on the micro controller to position 1-2.
This option may be fitted at order placement or retro fitted subsequently. The
Option PCB assembly is fitted above the Micro controller on four hex pillars.
A 16-way ribbon connection is made from the Option PCB to SKK on the
micro controller card. The links on the Option card are set as below. This
option is purely a hardware change and no configuration is required using
MXTOOLS.
