STEP 2: Attach the power supply
The TCC-100 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
the TCC’s 3-connector terminal
block to the DC power supply, as
shown in the figure. Once the power
supply is connected to its p
ower
source, the PWR LED located on
TCC
’s top panel should turn red.
NOTE
The TCC-100 series supports 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 the TCC-100’s
RS-422/485 terminal block.
2-wire RS-485
When using the 2
-wire RS-
485 wiring
option, connect three wires from
the
TCC
-100’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
the
TCC
-100’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.
