TM
* Such as B&B Electronics Model 485SD9TB. See wiring on back of sheet (over)
Connects a Level TROLL directly to a controller or logger for communication via:
• Analog (4-20 mA) • RS485 Modbus
• SDI-12 • RS232 Modbus (with a customer-supplied converter)
Twist-Lock connector mates with probe body. Stripped & tinned wires on opposite end
for wiring to PLC or logger. Vented cable includes removable outboard desiccant to
protect cable vent tube from condensation in high-humidity environments.

CONNECTIONS
Refer to wiring diagrams on back of sheet. Trim back and insulate unused wires. The
shield should be wired to a chassis ground or earth ground.
Power Connections. The Red wire provides power for Modbus and SDI-12 modes.
The Brown wire provides power for the 4-20 mA mode. If power is present on the Brown
wire and not on the Red wire, the device enters the 4-20 mA mode automatically and
stays in the 4-20 mode until power is removed from the Brown wire or is applied to the
Red wire. The Red wire has priority — if power is applied to both wires at the same time,
the device will operate in Modbus or SDI-12 modes but not in 4-20.
Communications. The device automatically switches between Modbus and SDI-12
modes depending on which of the two interfaces has activity. Modbus and SDI-12
cannot be used at the same time — whichever one is currently in use will block commu-
nication on the other.
To communicate with the Level TROLL using Win-Situ ® 5 software through a serial COM
port: Cable can be wired to a port-powered RS485-RS232 converter* for temporary
connection to a serial port on a PC.

TIP: The desiccant may be removed
from the vent tube, if needed, for
better access to the conductor wires.
Pull the vent tube extender off the cable vent
tube to remove. After connecting and trimming
wires, attach desiccant vent tube to cable vent
tube and secure desiccant to cable with hook-
and-loop strap, as shown in the photo above.
