FAQ: Wiring Controllers
Q: Wiring controllers to Secure Solutions Matrix?
A: If you are connecting a TM99 or MM500TX controller they must be connected to the matrix via a TM99INT/1, which is connected to the Master Port on the Matrix.
If an MM500TXA or MM500TXB controller is being used then they can be connected directly to the Master Port of the Matrix with a D-connector lead wired with pins 1&6 straight through from the Comms Port of the controller.
