POWERMAX65/85 SERIAL COMMUNICATION PROTOCOL
Overview
Both the Powermax65 and Powermax85 can support serial communications with a CNC. A five-pin serial port
sends and receives the signals over an RS-485 connection using the ModBus ASCII serial protocol. The power
supplies require both the serial port and the machine interface port (CPC connector) to be installed to provide full
communications capability. Both ports are located on the rear panel of the Powermax65 and Powermax85:
Power Supply Hardware Requirements
Machine Torch
Using the Powermax65 and Powermax85 in a mechanized application requires a machine torch. Either the M65/M85 or
M65m/M85m can be mounted to an X-Y table or other platform. See the Powermax65/Powermax85 Operator Manual
(806650) for more information on mounting a machine torch.
Communication Ports
The Powermax65 and Powermax85 may not have either the serial port or machine interface port installed at the factory.
