Serial Connector
Use the SERIAL connector on the Rear Panel to interface the leak detector to a PC
via an isolated RS-232 connection. Table A-5 and Figure A-1 provide details of the
connection. A typical connection from a 9-pin PC serial connector requires a
female-to-female, 9-pin, null modem cable, where pins 2 and 3 are crossed.
