Figure 1-5: CRT to SIB Connections
NOTES:
1)
Outputs are power limited (for device/circuit ratings, refer to Appendix A).
2)
Make connections with overall foil/braided-shield twisted-pair cable.
3)
Apply power to the CRTs before start-up of the system beginning with the last CRT in the chain.
4)
A total of 25 CRTs can be installed. Only one keyboard (shipped with each CRT) can be used in the entire
system and installed on the first CRT in a chain. For all applications, use the keyboard to program the
FACP. When finished programming the system, remove the keyboard or keep the keyboard in a locked
enclosure.
