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 Print LB/KG for at least three seconds, or until the scale emits two quick beeps.

NOTE: If the scale does not beep after five seconds, release Print LB/KG 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

Table 5-1. Print Format Tokens

60.1 KG= -60.1KG

In BMI mode (displaying the BMI value), the scale will send out the following data:

PATIENT WEIGHT 60.1 KG
PATIENT HEIGHT 170.0 CM
PATIENT BMI 20.8

Example in KG:

-60.1KG
-170.0CM
<20.8

Example in LB:

132.4LB
-5-07.5FT
<20.4

In case of under weight or over weight, the word Under or Over will be sent correspondingly.

5.2 Communication Protocols

The scale has two communication protocols, escape and maintenance protocol.

5.2.1 Escape Protocol

An escape protocol is where the escape (0X1B or ASCII 27) is used to indicate that there is a command following. On the PC side there must be a listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues regarding data integrity to make sure that the data that was sent and received is valid.

Two examples include:

• Scale initiated communication
• PC initiated communication

The escape protocol commands table shows (below) what can be sent across communications lines.

Table 5-2. Escape Protocol Commands

ESC characters that will be used is shown below.
