What cable do I need to connect a Zelio Logic smart relay (SR2/SR3) to PC?

The Zelio Logic range of smart, programmable relays have a special communication port which enables them to be programmed and set up using a PC.

The communication ports on a PC are usually USB or 9-way SUBD. Schneider sells cables that are able to adapt to both these types of port.

For the SR2 or SR3 relays:

SR2USB01: Connecting cable with USB type PC connector, length: 3 m
SR2CBL01: Connecting cable with 9-way SUB-D type PC connector, length: 3 m

An SR2CBL06 cable can be used to adapt the USB port of the SR2USB01 cable to the 9-way SUB-D port of the PC port and vice versa.

For the old SR1 range:

SR1CBL01: Connecting cable with 9-way SUB-D type PC connector, length 1.80 m.

Please note - The connecting cables are specific to a range, thus the PC - Zelio Logic connecting cables used for the SR2 or SR3 is incompatible with the SR1 range.
