Acknowledge prompt
After receiving a valid command from controller, the CU will reply with the prompt >
(0x3E) to signal that it is ready for the next command. The controller shall not send
another command to the CU before receiving the > message from the previous
command. The only circumstance you are allowed to send a command without >
acknowledgement is due to timeout ( > not received after 5 seconds since last
command sent to CU).
Communication with the CU requires the external controller to log in to the Quinta CU
(refer to chapter 2.1: U commands Login to communication port).
1.4 Control Mode: Stand-alone or PC-controlled
The Quinta system offers two different control modes: stand-alone mode is used
without any software; an external controller can also send commands to control the
Quinta system in this mode. In PC-controlled mode, control of the Quinta system via
software is required; this can be Quinta software or third-party software.
With some command structures it makes a difference whether the system is used in
stand-alone mode or PC-controlled mode. For example, the a message, which follows
the q message of the MU, is only used in PC-controlled mode, since it is needed for
internal reasons in this case.
If there are concrete differences, these are explained in the description of the
commands in order to exclude possible incorrect use of the commands.
