5. All connectors are on the right-hand side of the connector panel and each has
a securing tab that must be pressed to allow the connector to be removed.
Press each tab and remove the connectors in turn.
6. Remove the main RT COM module earth cable from the RT COM module earth stud.
There should now be no further electrical connection into the RT COM module.
Finally, loosen and remove the six mounting nuts around the body of the RT COM
module connecting it to the display module and lift away the RT COM module from
the display.

Installing a replacement MTL RT COM module
The replacement of an RT COM module after the removal of another is effectively a
reversal of the removal process.
1. Ensure the rear of the display module is cleared of any small items or
contaminants and the underside of the RT COM module is similarly clean
before mounting it onto the six mounting studs attached to the rear of the
display module.
2. Hold the RT COM module in position while fitting the six retaining nuts onto
the studs and tighten them to a recommended torque value of 2 Nm.
3. Re-attach the main RT COM module earth cable to the RT COM module earth
stud and tighten the retaining nut to a recommended torque value of 2 Nm.
4. Re-connect the Keyboard into the ‘KB’ connector and similarly any pointing
device to the ‘PD’ connector along with associated USB and RS232
connections. Note that both of these have retaining clips which will click into
place when the connector is fully seated.
5. Re-connect the LVDS (Video) signal cable into the ‘J302’ socket and re-attach
its earth cable to the LVDS signal earth stud to ensure a good earth
connection.
6. Feed the RT COM module’s power cable through the right-hand (M16) cable
gland of the WS PSU allowing sufficient length to make the connection to the
spring terminals marked “Comms” inside the module.
7. Push the three wires (white, red, black) into the ‘Comms’ spring-clamp
connectors of the power supply as shown on the right of the image below.
Ensure that the cable colours are in the same order as shown, or refer to the
circuit board silk-screen markings and the table below.
