The four RS-422 ports are software-configurable to be that for either a controlling device or, more
commonly, a controlled device.
Above is shown the industry standard wiring for a controlled device, which is the configuration used
for all the editor interfaces currently supported. In most cases only a pin-to-pin cable is required to
connect these sockets to an external editor.
If the port should ever be configured as a controlling device, simply exchange the words “Transmit”
and “Receive” to arrive at the correct wiring.

As can be seen from the above, the HD1000 Mainframe is configured as a DCE (not DTE) RS-232
device, therefore only a pin-to-pin cable is required to connect this port to a PC. This configuration
is permanently fixed.
