Connecting with RS232 Serial Port
1. If using an RS-232 connection, connect the serial interface cable to
the interface board and to the matching port on the back of the com-
puter.
2. Connect the power supply connector to the serial interface cable. Plug
in the power supply.
3. Turn the terminal/computer power back on. The engine beeps.
4. If connecting the engine using an RS-232 interface, all communication
parameters between the engine and terminal must match for correct
data transfer through the serial port using RS-232 protocol. Scan the
RS-232 interface bar code below. This programs the engine for an
RS-232 interface at 115,200 baud, parity–none, 8 data bits, 1 stop bit,
and adds a suffix of a CR LF.
