560-10-1 Digital Chair Scale

5.0 Communication
The unit 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. That connection is shown in USB Connection section. The RS-232 parameters are:
· 9600 baud (selectable in the programming mode) · 8 data bits · 1 stop bit · no parity · no handshaking There are three methods of communication: · Push- button keypad print · Standard remote protocol · Escape protocol
5.1 Push-button Keypad Print
With a stable, in-range weight, press and hold for at least three seconds, or until the scale emits two quick beeps.

Note If the scale does not beep after five seconds, release

as the weight was either in motion or out of range.

If displaying weight and not BMI, the scale will send out the following 21 character string: xxxxxxxxxuummmmm
