HAND/OFF/AUTO Switches

Each output on the M2000 has a dedicated switch that lets the user manually override the activity of the
output. "HAND" mode (switch at rightmost position) fully activates the output (24 VAC for digital outputs,
10VDC for analog outputs). "OFF" (switch at center) deactivates the output and "AUTO" (switch at left)
returns control of the output to the program in the M2000's microchip.

Jumpers

The M2000 has jumpers that are externally accessible (see Figure 3), as well as jumpers that are on the
lower internal board (see Figure 4), that allow for configuration of various hardware elements.

Figure 3 - Location of the EXTERNAL jumpers

• INT: These are the jumpers for the bias and terminating resistors used for the interface communication
bus. See the ProLon network guide for information about bias and terminating resistors.
(See Figure 5)
• NET: These are the jumpers for the bias and terminating resistors used for the network communication
bus. See the ProLon network guide for information about bias and terminating resistors.
(See Figure 5)
• AI 1 - 9: These jumpers allow the user to select the signal mode of the associated analog input.
(See Figure 6)
