INSTALLATION
Physical installation of the VCRC-P unit is relatively simple, although various configurations are possible.
DIRECT RACK-MOUNT HOOK-UP
Regardless of the location of a VCRC-P unit, it will more than likely be installed in a rack (refer to Figure 14). The VCRC-P unit mounts in a standard 19-inch (48.26 cm) rack and occupies only one RU (1.75 inches or 4.45 cm) of rack space.
REMOTE OPERATION
If it is desired or necessary to place the VCRC-P unit some distance from the controller (CM9760-CC1), the wiring run from the CC1 to the RJ-45 IN port should not exceed 4,000 feet (1,219 m).

DAISY-CHAINING
Up to 39 VCRC-Ps can be daisy-chained together. This enables the system to support up to 2,496 VCRs. Figure 15 illustrates the required wiring connections for daisy-chaining.
Note that the remarks made in the previous section regarding RS-422 wiring run distances also applies here when considering cables distance runs between daisy-chained units.
