Appendices 67

Appendix C: EVR1500 Environmental Monitor Appliance Pinouts

This appendix provides pinouts and signal definitions for the following EVR1500 environmental monitor appliance connectors: analog sensors (RJ- 45), digital I/O (eight-wire insert), COM1 (RS-232) serial port, Ethernet 10/100 BaseT and VGA display. Figure C.1 shows the digital I/O connections on the appliance terminal blocks.

Digital I/O connectors

Each digital I/O requires two connections, as shown in Figure C.1. Digital inputs (1 to 6) connect to dry contact closures. Digital outputs (7 and 8) provide Ø or 5 VDC and require ground connection.
