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
or a modem (DCE equipment). Instructions for configuring the DTE/DCE
switches SW2, SW3, SW4, SW5, SW6, SW7, SW8, and SW9 are shown in
.
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.
