again.
Transmit a Weight String Use numeric ASCII characters followed by a <CR> character.
Example:
• To display 1000, transmit: 1000<CR>
Transmit Status Characters Status characters may be imbedded anywhere in the weight string to control
the annunciator lights. Status characters may be upper or lowercase, and in
any order, before or after the weight.
Example:
• To display 1000 lb gross, transmit: 1000LG<CR> -or- GL1000<CR>
Control Commands Control commands are single ASCII characters (followed by <CR>) that are
transmitted to the XR to control additional features such as the built-in traffic
light (XR 4500TL) and the traffic light relay.
