Environmental Specifications
The power supply will be a 65W universal input switching power supply that is UL
safety rated. We expect the system to operate without a need for a fan in air conditioned
locations. The fan will be electronically controlled via temperature sensor. This will
allow the unit to operate under less than optimal conditions.
8.4 M&C Interface Connector
The Monitor and Control (M&C) port allows basic configuration of the XDS receiver via
an asynchronous RS232C electrical interface. It uses the following protocol settings:
115.2K baud, 8 data bits, No Parity, 1 stop bits, and no hardware flow control. In addition
to the asynchronous interface, the M&C connector provides a status relay output and four
optical inputs. The four optical inputs are activated grounding the input signal. The
following table provides the pin-out for the M&C port.
