Results may vary, depending on the computer being used. Other models, even from
the same manufacturer, may not yield the same results.
The procedure in this section provides details for RS-232 communication between
the PC and the WPR-48. Refer to the figure below for a typical connection diagram
when upgrading firmware.
NOTE: Use an RS-232 cable (RJ-11 – DB-9) to connect the WPR-DS docking
station to the serial port of the PC. This connection can be made with a modular
RJ-11 cable and a DB9F to RJ-11 adapter. (Refer to “Configuring the WPR-48” on
page 5 for details).
NOTE: The connection to the WPR-48 is through the charging contacts of the
WPR-DS. During a firmware upload procedure, the charging circuits are
automatically disconnected.
