Hardware Description & Installation Manual
System Control
The following table lists the purpose of each connector associated with system control, on
Output A, and Output B.
RS-422 connection diagram
The pinout for the RS-422 signals on the RJ-45 connectors, and the wiring diagrams for the
appropriate adapters, are shown here:
Standard wiring between multiviewer and devices wired to SMPTE “slave” specification (e.g. most
routers, Ross Synergy switchers, Nevion ETH-CON)
Standard wiring between multiviewer and devices wired to SMPTE “master” specification (e.g. Philips
Jupiter router control system, Grass Valley Presmaster PCS)

a. The Kaleido-MX multiviewers’ RS-422 ports have an RJ-45 connector in order to preserve space on a busy
panel. The RS-422 interface specifies a DE-9 connector, so if you are using this interface, you will require a
DE-9-to-RJ-45 adapter. Grass Valley supplies two adapter models, correctly wired for this application: a
straight adapter (part no. 1737-3000-102), and a crossover adapter (part no. 1792-3700-100).
Connect to an RS-422 (SMPTE ST 207, EBU-3245) or
RS-485 device or network
Note:
The multiviewer’s RS-422 ports have no ground pin. Using the
appropriate DE-9S-to-RJ-45 adapter, an external device should be able to
communicate with a multiviewer despite the lack of a ground.
