When the TIO device is set as the last device on the RS-485 bus segment and
220 Ohm bus termination is required, set the jumper J2G to position 19-20. This
will result in connection 220 Ohm resistor between RS-485 (+) and (-) terminals.

Digital and Pulse Optically-Isolated Outputs
Connections
TIO is equipped with two programmable digital optically-isolated outputs. Each
output can be assigned to any one of many different system events or config-
ured as a pulse output (see Paragraph 5.3.9).
Digital optically-isolated outputs use dedicated 4 position 3.5mm male terminal
block header J1 located on the top side of the TIO enclosure (see Figure 6.1).
(Mated interface connector: Tyco Electronics P/N: 284510-4).
Optocoupler #1 - Terminal J1 (pins 1 and 2):
Plus (+) (passive) --------------- Terminal J1 pin 1
Minus (-) (passive) --------------- Terminal J1 pin 2
Optocoupler #2 - Terminal J1 (pins 3 and 4):
Plus (+) (passive) --------------- Terminal J1 pin 3
Minus (-) (passive) --------------- Terminal J1 pin 4
WARNING: Optically-isolated outputs require application of external
DC voltage across terminals. Do not exceed maximum allowed
limits for voltage and current provided below:
2 V < UCE < 40 V
0.2 mA < ICE < 150 mA
