SERIAL CONFIGURATION
All models are fitted with 1 TTL serial channel for:
o Copy card connection to upload/download parameters.
o Serial communication with personal computer via RS-232/TTL conversion modules.
The TTL serial - referred to as COM1 - can be used for:
 configuring parameters with the ParamManager or DeviceManager software using the Eliwell protocol
 configuring parameters and monitoring with Televis Net software using the Eliwell or Modbus protocol PC
Interface connection modules are required.
 configuring device parameters, states, and variables with the Modbus via the Modbus protocol
For selection of the protocol and setting of the device address, see the following table:

IMPORTANT: DO NOT supply power via TTL present on PC Interface 2150 to the EWCM4120-4150-4180 device.
To avoid errors, it is OBLIGATORY to cut the wire corresponding to 5Vdc of the 5-pole TTL connector, as illustrated
in the figure:
