RCL

The Modbus interface, used to communicate with a GTC, is available as an option, factory

assembled or with a kit.

Caution

The use of the µBMS recall command is not compatible with the modbus communication. The

same terminals and addressing DIPs are used in both connection cases.

Caution

Shielded twisted pair wire must be used for interconnecting wiring. Wire impedance must be

between 100 and 130 Ohms and the wire surface section must be between 0.12 and 0.5 mm² (26

to 20 AWG). Larger wire may be used, but in this case connection to the terminal blocks can cause

problems.

Caution

28 SYSHRW

The MODBUS supervision can be connected to a maximum of 123 appliances.

The maximum distance between the RCL and the first unit is 30 metres.

The maximum distance between the RCL and the furthest unit is 100 metres.

Note

: When MODBUS supervision is used, all the units must have a unique address (see "Addressing

procedure").
