Bias is provided by 4.7kΩ pull-up/down resistors on
the Data-In lines. This value is adequate for most
applications without termination. If another value is
required, space is provided on the PC for through-hole
resistor placement (R12, R21, R14, and R23).
Biasing application notes are also available on the
website.

Connections: Ground/V(-) = M V (+) = J
NOTE: Terminal block and DIP switch factory
default settings are shown on the product.
Two sets of DIP switches must be set, one for each side.
Setting the baud rate to 9600 will generally allow you to
communicate with higher baud rates.

You can perform a loopback test by connecting either an
RS-232 to RS-422/485 converter or a USB to RS-422/485
converter to the BB-485OPDR.
Jump L to K and H to G and power the BB-485OPDR.
Set DIP switches to RS-422 or RS-485, depending
upon what you are using to connect to the PC. Set the
baud rate to 9600.
Using HyperTerminal or a similar program, connect to
the appropriate COM port. Remember to set the baud
rate to 9600. Turn off HyperTerminal local echo. Start
typing. If you can see the data you are typing, the
loopback is successful.
