Description of syntax expansion
7.2.2
RS-232 Protocol: Basic Mode
Command syntax (to device):
<basic command protocol> => <command data> <CR>
Response syntax (from device):
<basic response protocol> => <STX> <response data> <ETX>
In the “Basic” communications mode, a master-slave protocol is used, whereby the device will only
transmit in response to a received command.
When the device receives the <basic command protocol>, <command data> will automatically be stripped
of all space and control characters, and all text will be converted to upper case. This simplifies
communications with the device when commands are being manually typed in from a generic terminal
emulator.
