Davis Adapter Board

Expansion cable the connects the X-600M to its expansion module. Provides both power and communication.


This cable is required to connect expansion modules to an X-400 or X-600M controller. The ribbon cable provides both communication and power connections to the expansion modules.

X-600M with Expansion Modules and Expansion Cable


  • 2-33 positions, 2.5-inches between connectors
  • 1.7A max current
  • Custom number of connectors
  • 10-conductor ribbon cable with connectors
Expansion Cable


Expansion cables (10-conductor ribbon cable) are necessary to connect expansion modules to an X-400 or X-600M controller. The large expansion modules (X-18s, X-19s, and X-20s) have two expansion ports, and come with a 5-inch expansion cable with two connectors which allows it to connect to the X-400 or X-600M along with other expansion modules.

We recommend to first connect all large expansion modules to the X-400 or X-600M, and then connect any smaller expansion modules (X-11s, X-12s, X-13s, X-15s, X-16s, X-17s). See Example

To know which expansion cable you need, fill out the form below:


Expansion cable (2 connectors): $10.00

+$5.00 per additional connector

How many expansion modules will be connected to an X-400 or X-600M Controller:

LARGE expansion modules
(X-18s, X-19s, X-20s)
SMALL expansion modules
(X-11s, X-12s, X-13s, X-15s, X-16s, X-17s)
You will need the following expansion cable: No additional cable needed


*You cannot have more than 64 expansion modules per X-600M controller or 32 expansion modules per X-400 controller.

**If you have more than 32 expansion modules, a power injector will be required.
