The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing System. Figure 3-18 on page 9 shows where the RS-232 connection is. The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and no handshaking.
Connecting software and downloads should be addressed by your IT department and can vary depending on what type of computer platform you’re using.
