RS-232 Communication
The scale comes with an RS-232 port that enables weight data to be transmitted to other equipment, such as a
computer or printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing
Systems. Figure 3-4 on page 5 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.
There are three methods of communication:
•
Pushbutton keypad print
•
Escape protocol
•
Maintenance protocol
