Kaleido-MX 4K (1RU)
Hardware Description & Installation Manual
The Kaleido-MX 4K 16 × 1 has two Ethernet connectors, labelled ETHA (for Output A), and
ETHB (for Output B). The RS-422 port is located at the other end of the rear panel, next to
the input module connectors. The following table lists the purpose of every connector
associated with system control.
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)
Connector label Connector type Function
ETHA, ETHB RJ-45 100 Base-T Ethernet connection
RS-422 RJ-45 Connect to an RS-422 (SMPTE ST 207,
EBU-3245) or RS-485 device or network
Note: The Kaleido-MX 4K 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).
