The INTRAC-305 is wired as a DCE unit suitable for direct 1
to 1 connection to the 9-way serial port of a PC AT.
TXD and RXD data flow directions are standard (relative to
the DTE). Handshake lines are pulled to the ON condition.
The factory default setting for the three serial ports is RS423.
The set-up for RS422 is shown over page.
