Trooper Count Scale
3.7 RS232 Communication
All communication is accomplished using standard ASCII format. Characters shown in the following table are acknowl-
edged by the Scale. Invalid command response "ES" error indicates the Scale has not recognized the command.
Commands sent to the Scale must be terminated with a carriage return (CR) or carriage return-line feed (CRLF). Data
output by the Scale is always terminated with a carriage return-line feed (CRLF). See section 4.7 for RS232 and Print
Setup.
