Connecting Panels to Other DLM Devices, and Panels to Panels
There are two DLM local networks (labeled A & B) used to connect DLM devices such as switches, sensors, photocell input modules,
and room controllers. The networks are labeled A and B. Each network has two RJ-45 jacks, for connecting Cat5 cable. Only LMRJ
cable should be used. It is not important which jacks are used. For more details, see “Connecting Switches, Sensors, Photocells, and
Other DLM Accessory Devices” on page 11.
Panels can also be connected to each other, using the MS/TP connectors and LM-MSTP wire.
Connecting Override Switches Directly to a Panel
Non-DLM switches can be connected directly to the LMCP, using the Remote Override Terminals next to the Relay Connection Headers.
Only a 2 wire momentary switch, with or without a pilot light, can be connected. If both the pilot light and the momentary switch are
part of the same device, then it is likely that there will be a single “common” or “ground” signal; it can be wired to either of the terminals
labeled C.
Load Numbering
Load IDs are assigned on the panel based on the LMRD cards. Loads are numbered on a single card from top to bottom. With multiple
cards, numbering continues from left to right, top, then bottom. So on an LMCP-48, loads are numbered as follows:
• Top Left Card – Loads 1–12 • Top Right Card – Loads 13–24
• Bottom Left Card – Loads 25–36 • Bottom Right Card – Loads 37–48

Termination Resistor
Differences between the rev 3 LMPI board and the rev 6 LMPI board:
• The Pull Down, Pull, Up, and Termination Resistor are jumper plugs instead of dip switches.
• There is no SD Card Slot (not currently used)
• Microcontroller and LMRD Status LEDs silk screen labeling changed on rev 6 board
• Group button silk screen labeling simplified on rev 6 board
