Installation

STEP 2: Attach the Power Supply

V+

Power Supply

12 - 48 VDC

TCC-100 Series is powered by an

external 12 to 48 VDC power supply. To

connect the power supply, run two wires

from the V+ and V- terminals on TCC’s

3-connector terminal block to the DC

power supply, as shown in the figure.

Once the power supply is connected to

its power source, the PWR LED located

on TCC’s top panel should become

illuminated in red.

NOTE: TCC-100 Series provides reverse power protection. I.e., it will

automatically detect which power wire is negative, and which is positive.

STEP 3: Wire the Terminal Block

There are three wiring options available for connecting to TCC-100 Series’s

RS-422/485 terminal block.

2-wire RS-485

When using the 2-wire RS-485 wiring option,

connect three wires from TCC-100 Series’s

terminal block to the opposite connection. As

shown in the figure, connect from Data+ to

Data+, from Data- to Data-, and from SGND

to SGND.

4-wire RS-485

When using the 4-wire RS-485 wiring option,

connect five wires from TCC-100 Series’s

terminal block to the opposite connection. As

shown in the figure, connect from Tx+(B) to

Rx+, from Tx-(A) to Rx-, from Rx+(B) to

Tx+, from Rx-(A) to Tx-, and from SGND to

SGND.
