K2 Media Server connector pinouts
The following sections describe K2 Media Server rear panel connector pinouts.
Redundant server heartbeat serial cable
Take care to use the proper serial cable to interconnect redundant K2 Media Servers that take the
role of file system/database servers. This cable supports the heartbeat mechanism whereby the
servers monitor each other’s health. It is a 9 pin serial cable, but it is not a standard RS-232 null
modem cable. The heartbeat cable is supplied with your system (Grass Valley part number
174-8137-00) and has a pin configuration as follows:
1 – 4
2 – 3
3 – 2
4 – 1&6
5 – 5
6 – 4
7 – 8
8 – 7
9 – No Connect
