*Note : All RS232 signals are present in RS422 mode.
The RocketPort interface box can only be used with the Rocket Port 550-8 and
RocketPort 550-16 (or the Universal 550 equivalents). 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 (or the Universal
550 equivalents) may connect to the Comtrol Universal Interface (UI). Refer to the UI
manual for connector pin-outs.
The Quad, Octa, RJ11 and RJ45 RocketPort 550 versions do not support RS422 mode.
