System Overview
Serial UART API – S1C Commands
API
V5.4
Getting/Changing Configuration Settings of S1C enable devices
All commands are formed normally using text-based strings and communicated to
the device by one of the following methods.
A bi-directional serial link. The link will currently be based around a logic level
serial port with or without CTS/RTS handshake with a default baud rate of
57600. Note that TCS standard serial I/O will not tolerate full RS232 voltage
levels, also RS232 has inverse logic.
For Bluetooth Low Energy enabled devices.
The method to be used to read or change values with the System One Controller
(S1C) using simple control request messages. These requests can be to retrieve
information or to change settings. The S1C will respond back the requested data or
acknowledgment of changes made.
All control messages and replies can be checked using simple terminal software, i.e.
Teraterm for serial links
Command Syntax
Commands and replies are formed as readable ASCII strings.
Commands/queries/replies start with a ‘#’, this start character is followed by the
command/query string which is then followed by a ‘?’ for queries or an ‘=’ for
commands/replies.
All commands and queries are case sensitive, currently all upper-case and 4 ASCII
characters long -
excluding ‘#’, ‘=’ or ‘?’.
All commands and queries must be terminated with a <LF> or a <CR>+<LF> (0x0a
or 0x0d,0x0a)[‘
\
n’ or ‘
\r\
n’]. A
ll non-binary replies will be terminated with a single
<LF>
Command value strings must not exceed 112 bytes to be compatible with the BLink
network.
