3.0 CONNECTING METERS TO THE IDR
Honeywell E-Mon Meter Connections
1. Each Honeywell E-Mon meter has two modular jacks located at the top of the main circuit board. The jack
on the left (RJ-45, 8-pin) is used to connect the meter to the IDR.**
NEVER USE 6-PIN JACKS LABELED "PORT 0" OR "PORT 2" TO CONNECT A METER TO THE IDR.
2. * All Honeywell E-Mon meters must be connected to meter jacks #1-8 using 6-conductor flat modular
cable.**
3. *IDR-16 - If the IDR is an IDR-16, connect the additional meters to Jacks #9-16 on the circuit board using
6-conductor flat modular cable.**
4. IDR-8s supplied with plug-in screw type connectors can be up to 500 feet from all meters, and utilize a pair
of wires for connecting to the meter pulse output.**
* See Appendix D for item 2&3 above.
** For more information on cable assembly, see Appendix B.
Pulse Output Meters (IDR-ST Models Only):
1. Each meter is interfaced with the IDR through the plug-in screw type connectors. Any of the connectors
may be used with #22-14 AWG conductors.
2. When used with solid-state switches, correct polarity must be observed in order for that contact to be rec-
ognized. The left terminal of the screw-terminal on the IDR must be connected to the plus (+) side of the
switch.
3. The meter can be up to 500 feet away from the IDR.
Third-Party Meter Connections
In order to connect "third-party" meters such as gas, water or utility-type meters, the IDR must be ordered with
the "two-screw" connectors (designated with the suffix ST at the end of the model number) terminals instead of
the modular jacks that are used with Honeywell E-Mon meters.
The input pulses supplied to the IDR must be non-powered. Pulses can be either physical (mechanical) contacts
or electronic switches. When electronic switches are used, the left terminal on the IDR is the "+" output and the
right is the return from the switch.
