TARGAS-1 Operation Manual V. 1.02
126
Only commands that are less than 90 characters in length will be successful. If a CRC-8 is present, the
CRC-8 also needs to be correct in order for the command to be successful.
On successfully receiving the command string, TARGAS-1 sends an acknowledgement by sending to the
Host a ‘+’ followed by a <CR>.
On a failure, a ‘–‘ is sent back to the Host with a <CR>.
A failure can be caused by a string longer than 90 characters or an incorrect CRC.
Receiving a response
Depending on the value of the CRC parameter, a CRC will/will not be appended to the command
received from the TARGAS-1. If the CRC parameter value is ‘0’ (CRC Off), no CRCs will be appended to
any of the commands received from the TARGAS-1. If the CRC parameter value is ‘1’ (CRC On), CRCs
will be appended (including the ‘C’) to all commands received from the TARGAS-1. See Get/Set
Parameter Values Table on page 132 for more details on turning off/on the CRC.
For example,
With CRC=0 (CRC Off):
Received from TARGAS-1: G,1,25<CR>
With CRC=1 (CRC On):
Received from TARGAS-1: G,1,25,043C<CR>
The following table describes the TARGAS-1 Command Set that can be used by the Host to
communicate with the TARGAS-1. Note, the examples shown below have CRC disabled (CRC=0). There
are two types of commands; Auto and Standard. Auto commands are commands that the TARGAS-1 will
send without being prompted by the user. For example, the ‘W’ (Warm Up) command is automatically
sent by the TARGAS-1 when it is warming up. Standard commands are commands that are sent by the
user. Standard commands can be only a single character, or a single character followed by one or more
parameters. All commands are terminated with <CR> which represents a carriage return (ASCII 13).
