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 –RESET signal 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)
JP4 I/O ADDRESS
This jumper selects the I/O address range used by the LM104-P50:
Position 1 Address &h1E0-&h1EF
Position 2 Address &h300-&h30F
Position 3 Address &h310-&h31F
Position 4 Address &h320-&h32F
Default: Position 1 (&h1E0-&h1EF)
