4.5. BUS CAN
Data communication bus between the equipment and CAN peripherals (NS-CAN, NSD-CAN, MD-30C* and ME-200C*).
* If MD-30C or ME-200C microphone desks are to be connected, the IF-7WDCETH must be fitted with
the accessory module model IF-MER (code M240MER).
The default CAN communication speed set in the IF-7WDCETH is 33,333 kbit/s, which allows communication with NS-CAN, NSD-
CAN sensors and MD-30C or ME-200C microphone desks.
4.5.1. Connecting NS-CAN or NSD-CAN peripherals to the IF-7WDCETH
For CAN bus connection follow
figure 9. The use of a twisted pair,
shielded
cable
AWG24
recommended.
4.5.2. Connection of CAN microphone desks (MD-30C and ME-200C) to the IF-7WDCETH
ATTENTION: ONLY IF THE IF-7WDCETH IS INCORPORATED WITH THE OPTIONAL IF-MER MODULE
