The X75 is connected to a TCP/IP LAN (Local Area Network) or directly to a PC 

using connector J3.  This is a standard RJ45 network connector allowing connection 

of any generally available Ethernet cable.  Note that if the X75 is to be connected 

directly to a PC rather than a LAN then a cross-over Ethernet cable will be required.

Auxiliary connector J2 provides connections for an external temperature probe which 

can be supplied optionally with the system and for a single volt free contact closure 

input.  This connector accommodates wire sizes in the range #28 to #20AWG.

 

NOTE: Any sensor, such as a switch or relay, that is connected to the digital input 

MUST be galvanically isolated.

 

The optional temperature probe is identical to the battery temperature probe that is 

supplied as standard, so there is no risk of mixing the two up on receipt.
