Low Power Outputs
There are 12 negative or positive switching outputs and 4 negative or positive switching outputs. Each channel can be
programmed with individual voltage protection. Positive (12V) power is sourced via a set of power diodes from either Bank
A or Bank B supply inputs (whichever is higher in voltage).
With the exception of current limiting (there are none for the low power outputs), the features and configuration setup are
exactly the same as for the High Power Outputs. See Above for more information.

RS485 Serial Interface
The MCS-32 currently supports the MHE RS485 remote handheld interface. All communication for programming the unit

3.5
CAN Bus Serial Interface
The MCS-32 has two CAN2.0 full speed interfaces. The first interface is designated for local control using suitable MCS-32
compatible remotes, while the second is intended for bespoke vehicle communication. Consult with your installer for more
information regarding these options.

repeatedly press the diagnostic button to select the volume level required. The selected setting is shown on the
diagnostic indicators LED's:
1
Announcement speaker volume level setting.
2
PTT microphone volume level setting.
3
