Electro-Voice PWS-C User manual

PWS-C
Programmable
Wall Station
CAN Coupler
General Description:
Key Features:
• Up to 3 front units connectable - custom
composition of a wallstation is possible
• Selecting baudrate via DIP switch or software
- providing protection against unintended
baud rate change as well as high flexibility
• Integrated terminating resistor - no external
resistor for CAN bus termination required
• PCB terminal block for easy handling - dual
terminal for daisy chaining
• Status-LED - for local indication of connection
to the CAN bus
• Wide input voltage range for external supply
voltage - 9 V DC up to 58 V DC
Check the PWS manual and IRIS-Net
documentation for more details
The Programmable Wall Stations (PWS) are modular stan-
dard mount keypads for Electro-Voice NetMax systems. The
PWS-C CAN coupler establishes the connection between the
front units and the CAN bus. The PWS-C collects and trans-
mits the activity of control elements of the connected PWS
modules and sends messages via the CAN bus to controlled
devices. The PWS-C also receives data via the CAN bus and
displays it on the PWS modules. In this way, a bi-directional
communication between the PWS control surfaces an the
controlled devices is achieved via CAN bus.
