RS-232 Communication

4.0 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 4-3 on page 12 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

4.1 Push-Button Keypad Print

With a stable, in-range weight, press and hold the LB/KG/Print key for at least three seconds, or until the scale displays PRINT. Note that if the scale does not beep after five seconds, then release the button 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:

Where:

xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>

xxxxxxxxx is the weight with decimal point and " - " sign, if negative uu is the unit (lb or kg). mmmmm is the mode (gross or net)
Example:

60.1 KG= <PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>

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:
<PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF> <PATIENT><SP><HEIGHT><SP>-170.0<SP>CM<SP><CR><LF> <PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.8<SP><SP><SP><SP><CR><LF>

Example in LB:
<PATIENT><SP><WEIGHT><SP>132.4<SP>LB<SP><CR><LF> <PATIENT><SP><HEIGHT><SP>-5-07.5<SP>FT<SP><CR><LF> <PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.4<SP><SP><SP><SP><CR><LF>

4.2 Communication Protocols
The Rice Lake Digital Wheelchair Scale has two communication protocols, escape and maintenance protocol.

4.2.1 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
Table 4-1 is what can be sent across communications lines.

Maintenance and Troubleshooting

5.0 Maintenance and Troubleshooting

5.1 Maintenance
The following section provides instructions for maintaining and cleaning the Rice Lake line of scales.

IMPORTANT

Do not immerse the scale in cleaning or other liquid solutions. Do not use Isopropyl alcohol or other solutions to clean the indicator display surface.

5.1.1 Basic Maintenance Before using the scale and after periods of non-use, check the scale for proper operation and function. If the scale does not operate correctly, contact a qualified service personnel.
Basic maintenance includes:
· Check the overall appearance of the entire scale for any obvious signs of damage. · Inspect the condition of the AC adapter cord for cracking, fraying or broken/bent prongs. · Using an adapter that has been used elsewhere may cause issues with the scale. · Change batteries on a regular interval. Leaving in for long periods of time can cause batteries to leak.

5.1.2 Cleaning Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning the cleaning process, disconnect the scale from the AC power source.
· Clean all external surfaces with a clean, damp cloth or tissue. · Mild soap and water solution may be used. · Standing platform may be cleaned with Isopropyl alcohol · Dry with a clean soft cloth.

5.2 Troubleshooting and Testing
Refer to Table 5-1 to diagnose and correct failure prior to contacting service personnel.
