Serial Connections
The physical cabling required to connect a multiviewer to an external serial device (such as
a router, production switcher, or router controller) can vary from one device to another. It is
important to check the manufacturer’s documentation to get the proper pinout so it
matches up with the multiviewer.
The RS-422 ports at the back of a Kaleido-X16 multiviewer or at the back of a KXO-Dual or
KXO-Dual3 card (in the case of the Kaleido-X multiviewer models) use an RJ-45 connector.
Grass Valley provides two adapters, which map the RS-422 signals to the more common DE-
9 form factor:
• To connect a serial device whose RS-422 port is wired to the SMPTE slave wiring
specifications, use the straight adapter (Grass Valley part number 1737-3000-102).
• To connect a serial device whose RS-422 port is wired to the SMPTE master wiring
specifications, use the crossover adapter (Grass Valley part number 1792-3700-100).
The DE-9S pinouts for these two adapters are as follows:

Note:
Some routers have RS-232 ports, which will require the use of a RS-
232 to RS-422 converter (externally powered ones work best).
