ASYNC RS-232 TO 2-WIRE RS-485 CONVERTER
4. Installation
This section tells you how to properly connect the
Converter to the RS-485 and RS-232 interfaces, and
how to operate the Converter.
4.1 Connecting the EIA-232 Interface
The EIA-232 interface is factory-configured as DCE. It
connects directly to DTE such as a terminal or PC. If you
must use a cable to connect to the DTE and your DTE
device uses a DB25 connector, use a straight-through
cable no longer than 50 feet (15.2 m).
If your DTE equipment uses a DB9 connector,
use one of the two following Black Box DB9 to DB25
adapters: FA520A-R2 (DB9 female to DB25 male) or
FA521A (DB9 male to DB25 female).
For your convenience, the Converter comes with
either a male or female DB25 connector on the
RS-232 side.
