RS-422
When using the RS
-
422 wiring option,
first follow the 4
-wire RS-485 wiring
instructions given above.
Optional RTS/CTS Handshaking
Signals
If your software is set up to send and
receive RTS/CTS signals over separate
wires, you should also connect from
RTS+(B) to CTS+, from RTS
-(A) to
CTS
-, from CTS+(B) to RTS+, and
from CTS-(A) to RTS-.
STEP 4: Attach the RS-232 connector
Depending on your
application, use the
appropriate serial cable to
connect from
the TCC-100
product
’s RS-232 female
DB9 port to your RS

STEP 5: Test the connection
After configuring the DIP switches, connecting the power, wiring the
terminal block, and attaching the RS-232 connector, we suggest using a
console terminal program, such as HyperTerminal or Moxa Terminal
Emulator, to test the connection. If you have an RS-422/485 serial board
(such as the Moxa CP-132, a 2-port RS-422/485 board) installed in your
PC, you can connect your PC’s COM port to the TCC-100’s RS-232 port,
and then connect the TCC-100’s RS-422/485 terminal block to one of the
RS-422/485 serial board’s ports. Alternatively, if you have already set up
an RS-422 or RS-485 network, you can also connect the TCC-100’s
RS-422/485 terminal block directly to that network. Next, start
HyperTerminal or Moxa Terminal Emulator, and then open a connection
to both the COM port, and the port associated with the TCC-100’s
RS-422/485 port. Test the connection by typing a few characters on your
PC’s keyboard. The characters you type should show up in the
HyperTerminal window that is currently inactive, indicating that the typed
