3.3 Baudrate
This submenu allows altering the RS232 Baud rate. The following values are possible:
300 bps
600 bps
1200 bps
2400 bps
4800 bps
9600 bps
19200 bps
28800 bps
38400 bps
57600 bps
115200 bps
However, most scales should use 9600 bps. Some will have other (fixed) baud rates and
others will also have configurable values. You have to ensure that APR500 baud rate and
scale baud rate match, otherwise the communication does not work. Please also see the
scales manual for details.
3.4 RS232 format
This menu item determines the RS232 interface parameters "parity", "data bits" and "stop
bit". Normally "N,8,1" (no parity, 8 data bits and 1 stop bit) is the correct setting but there
are also scales - like Iconix - which could require "E,7,1" (even parity, 7 data bits, 1 stop
bit). This can also depend on the scales firmware version and settings. For further details
please see the scales manual.
4. Hotkey configuration
In order to instruct the APR500 to request the weight from a scale, the corresponding
Hotkey has to be configured accordingly. Since the reader has two programmable Hotkeys,
you can configure either Hotkey A or Hotkey B for requesting the weight. The functionality
of the Hotkeys has to be selected in the "Operation" menu.
