TM8250 connectors

The TM8250 control head has two RJ45 sockets for program-

ming, and a power on/off LED.

Note: The pins of the two programming connectors 

are connected in parallel, so care needs to be taken 

when connecting external devices to these connectors.

The pin allocations for these connectors are explained in the 

following diagram and table.
