Guidelines for connecting serial equipment
• A ‘straight through’ 9M-9F serial cable with all wires connected should be used to connect the
transmitter unit to the source PC (i.e. 1-1, 2-2, 3-3 etc.)
• The 9-way male connector on the receiver has the same pinning as a serial port on a computer
so any cable that may be used between a computer and a device can be used between a
receiver and the device.
• The equipment works by rapidly sampling the RS232 signals and transferring the signal states
between the receiver and the transmitter and vice versa.
• The transmitter and receiver combination can be thought of as being equivalent to a 9M-9F
serial cable with all wires connected straight through (1-1, 2-2, 3-3 etc.)
