• RS-232 Serial Automation Output: Provides serial connec-
tion to a local computer running automation software. A
straight through serial cable must be used.
• RS-232 Serial Printer Output: Provides serial connection to
a local computer or serial printer.
• 25 Pair Telco Connection: Connects directly to the local PBX
or to BP3X-3 (Refer to Appendix C for pinouts).
• Ethernet Output 10/100 BaseT: Traditional automation
communication is provided via port 1025 on the Ethernet
