STEP 5 - Power & Ground Connection
Figure 4. Black Box recommends that you ground the chassis as shown here.
Figure 5. Set the unit for RS-422/485 or RS-232 connection.
STEP 6 - Wiring Examples
1. Make sure that the chassis is grounded. Connect a
grounding wire from the ground lug to a good grounding
source.
2. Then connect the power. The terminal block will accept
28 to 12 AWG wire. Power requirements: 10 to 48 VDC,
2.6 Watts maximum.

STEP 8 - Loopback Test / Troubleshooting
BLACK BOX RECOMMENDS:
1. Configure the converter for RS-485 4-wire.
2. Set DIP Switch position 8 to “Off“.
3. Cross-connect the fiber optic TD and RD.
4. Connect a PC to the serial port.
5. Use HyperTerminal® or a similar program to
connect to the appropriate COM port. Turn off
hyperterminal local echo.
6. Transmit the data. If the same characters are
returned, the test is good.
