provided SMA and/or Size 8 contacts. The connectors are
mounted in a group of sixteen on rear panel I/O plates. These
plates can be arranged in a variety of ways to suit many different
requirements. Three types of 50

The Size 8 contacts are housed in DSUB combo housings in
groups of eight. The Size 8 plugs are housed in ITT Cannon P/N
DCM8W8PK87 plug housings and the Size 8 receptacles are
housed in ITT Cannon P/N DCM8W8SA197 receptacle housings.
Figures 3-3 and 3-4 shows the I/O configuration for option
