Jumper Settings

There are five jumper locations, which vary slightly depending on which network interface option is selected. Their functions are as follows:

JP1 SERVICE

Momentarily shorting this jumper causes the Neuron chip to broadcast its Neuron ID across the network. This jumper should normally be left open.

Default: OPEN

JP2 RESET

Momentarily shorting this jumper asserts the –RESETsignal on the Neuron chip. This resets the LM104-P50, restarting any application program. This jumper should normally be left open.

Default: OPEN

JP3 TERMINATION

This jumper controls whether or not the onboard termination circuit is enabled or disabled.

Shorted

Termination is enabled.

Open

Termination is disabled.

Please see page 7, “Cable Grounding and Termination” regarding termination issues.

Default:

OPEN (no termination)

Position 1 Address &h1E0-&h1EF
