The RocketPort interface box can only be used with the RocketPort 550-8 and
RocketPort 550-16. These controllers have a single DB25F mounted on the backplate
which connects via the RocketPort cable to the interface box. Alternatively the
RocketPort 550-8 and 550-16 controllers may connect to the Comtrol Universal
Interface (UI). Refer to the UI manual for connector pin-outs.
The Quad, Octa, RJ11 and RJ45 RocketPort versions do not support RS422 mode.
Pins 1, 9, 10, 11, 12, 13, 14, 21, 22, 23 and 24 of each 25 way connector are not used.
