K2 Media Client connector pinouts
The following sections describe K2 Media Client rear panel connector pinouts.
RS-422 connector pinouts
K2 Media Clients have been manufactured with two types of RS-422 configurations,
as follows:
• A K2 Media Client can have two RS-422 adapters. Each adapter is connected via
an internal USB cable to the motherboard, so while a RS-422 adapter does occupy
a rear panel slot, it does not plug into a PCI bus. Each adapter provides two RS-422
ports for connecting equipment for remote control of the K2 Media Client.
• A K2 Media Client can have one RS-422 adapter. The adapter is connected via PCI
slot to the motherboard. The adapter includes an external interface with eight ports.
On the external interface, ports 1–4 are active. This provides the four ports for
connecting equipment for remote control of the K2 Media Client.
The RS-422 interface conforms to ANSI/SMPTE 207M-1997 standard
(SMPTE 422).
Pinouts for the individual DB9 connectors are as follows:
