DTE/DCE mode
Each serial port can be configured to connect to a terminal (DTE equipment) or a modem (DCE
equipment). Instructions for configuring the DTE/DCE switches SW2, SW3, SW4, SW5, SW6,
SW7, SW8, and SW9 are shown in
settings
on page 109.
Example: Port 1 is changed from DTE to DCE by reversing every switch position on SW3 and
SW2; that is, switches that were off for DTE are turned on for DCE, and switches that were on
for DTE are turned off for DCE.
