• Modbus TCP/IP : Need the unit IP address.
• SNMP : Need the unit IP address and SNMP settings.

The 7" Color Touchscreen backpanel has two (2) paralleled 5-position Modbus RTU connectors at terminals RS1
and RS2. They enable upstream Modbus RTU connection and daisy chaining together multiple displays onto a
common upstream link.
4-wire Modbus RTU is the default setup. For 2-wire Modbus RTU, install jumpers on Pins 1 and 2 and Pins 5
and 6, see
Figure 2 .

RS485/RS422 cable length can be up to 4000 ft. if you use the correct cable:
• The cable resistance should be ≤ 27 ohms/1000ft @ 1 kHz and the mutual capacitance should be ≤ 14pf/ft.
@ 1 kHz.
• 4-wire cabling:
– RS422 is typically used for 4-wire.
– Use a shielded cable with two (2) twisted pairs and a shield/ground wire.
– The two transmit lines must be in one twisted pair and the two receive lines in the other twisted pair.
• 2-wire cabling:
– RS485 is typically used for 2-wire.
– Use a shielded cable with one (1) twisted pair and a shield/ground wire.

Infinity 2 Monitors have soft biasing (27K pull-up and pull-down resistors) on the + and – transmit and receive
lines. Therefore, if the customer’s Modbus client device allows for control, Eaton recommends that the user
turn on biasing and turn off termination, which may “fight” the biasing. Biasing the client device’s lines is not
critical because the Infinity 2 Monitor is already biasing the lines.
