EM510 Remote Control via LAN
4065.7763.32-01.00 5.140
With bits 0 to 2 and 7 to 10 and 12 to 13, the host can be informed via an SRQ about parameter
changes. Cyclical polling of the settings by the host is thus stopped during operation via several
interfaces or if the signal parameters are to be indicated. In the CONDition section of the register, the
change bits are set after a signal change and are reset by special query commands. Changes done by
another remote client affect the change bits equally.
