Commax Dp-ra01 Installation Manual May 2026
Most manuals show that the terminal block attaches to the wall bracket, not directly to the monitor.
This is where most DIYers get stuck. The DP-RA01 has a terminal block on the back (or on the mounting plate) with numbered posts. Here is the standard Commax 4-wire color coding logic.
Standard Commax Terminal Configuration:
Note: Always double-check the manual included with your specific door camera model. While the colors above are standard for Commax, variations exist in different production years.
If you are replacing an old unit: Don’t just guess. Take a photo of the old wiring with your phone before disconnecting anything. Match the wire colors to the terminal numbers.
If your DP-RA01 is broken and you cannot find an exact replacement, the Commax DP-R01A (newer version) is pin-to-pin compatible. The wiring and DIP switch settings remain identical to this manual. However, do not mix with 2-wire digital systems.
The DP-RA01 uses binary addressing. Set switches as follows:
| Unit # | Switch 1 | Switch 2 | Switch 3 | Switch 4 | | :--- | :--- | :--- | :--- | :--- | | 1 | ON | OFF | OFF | OFF | | 2 | OFF | ON | OFF | OFF | | 3 | ON | ON | OFF | OFF | | 4 | OFF | OFF | ON | OFF |
Note: The master door station must be programmed to call the correct monitor ID number. Refer to your door unit manual for call routing. commax dp-ra01 installation manual
