It is recommended that all interface cables are fully shielded cables.
An example of a Serial lead interface is shown in Appendix B.
2.4 Controller Operational Status LED Indicators
The Serial and USB controller PCB cards both have
Red
and
Green
LED indicators located in the
bottom right hand corner of the PCB, as shown in Figure 5 and Figure 6.
The LED’s are a quick way of determining the controllers operational status when power is applied to
the controller.
During the power up cycle the following LED routine should be observed:
1.
Apply power to the controller PCB card.
2.
The
Red
LED should illuminate straight away – this indicates there is power to the devices on
the controller PCB card.
3.
After the
Red
LED has illuminated within a time frame of up to a 5 second period the
Green
LED should illuminate. The illumination of the
Green
LED indicates that the controller PCB
card has gone through its start up routine and the firmware on board the controller is being
executed correctly.
Failure to see either of the LED’s illuminate as described in the above sequence will indicate a
possible problem with either power supply to the board or an on board controller firmware issue.
