2.4.3 20 mA Current Loop
The 20 mA current loop communication is provided on connector J6 of the CPU board (Figure 2-8,Table 2-2).
Ensure receive jumpers are across RX0, 20 mA and select active or passive switch settings. Remove any unused
jumpers. (Figure 2-9)
2.4.4 RS-232
The RS-232 connection is provided on connector J8 of the CPU board (Figure 2-8,Table 2-2). Ensure the transmit
and receive jumpers are across TX0 232 and RX0 232. (Figure 2-9)
2.4.5 RS-485
The RS-485 connection is provided on connector J9 of the CPU board (Figure 2-8,Table 2-2). Ensure the transmit
and receive jumpers are across TX0 485 and RX0 485. (Figure 2-9)

2.4.6 Reset Switch
The reset switch enables a simulated power up reset. It then goes back to normal operation mode. The reset switch
eliminates having to unplug the unit to do a reset. Refer to Figure 2-8 on page 7 for the reset switch location on the
CPU board.
2.4.7 Communicating with Indicators and LEDs
Small LEDs located on the CPU board flash when serial data is received or sent. The transmit indicators flash when
data is being sent out of the port. The receive indicator flashes when the data is received. A steady indicator on any
receive LED reflects a connection with no streaming data. See to Figure 2-9 on page 7 for communication indicator
locations on the CPU board.
2.4.8 Decimal Point (7-Segment Display)
The primary display board has decimal LED’s. These can be changed to commas by moving a jumper located on
the front of the display board shown in Figure 3-2 on page 10.
Ensure that the decimal point/comma jumper is in the proper position on the display board.
