H #
For example:
H 1
In this example, the interface will start sending heartbeat characters.
The heartbeat selection is stored in non-volatile memory and will be recalled on power
up.
Setting the slave support mode
The ‘S’ (slave) command is used to select whether the interface will support a Preset 10
slave station on the DMX port. When enabled, alternate start code packets are sent
from the interface and slave stations are allowed to reply to select presets. The default
value for this feature is 0 (disabled). When set to 1, slave stations are enabled. The
interface must be queried to determine the current active preset. When set to 2, slave
stations are enabled and the interface will send a message when a slave station has
changed the active preset. No query is needed to determine the current preset when
this parameter is set to 2. The format for this command is:
S #
For example:
S1
In this example, the interface will set to support slave stations, but it must be queried to
determine the current active preset.
The slave support value is stored in non-volatile memory and will be recalled on power
up.
Resetting the interface
The ‘$’ command is used to reset the interface. This special command does not need
the
the interface. This is equivalent to cycling the power to the interface.
Updating the software
The ‘U’ (update software) command is used to load new versions of the software into
the interface through the RS-232 port. There is a separate document covering the
details of this command. Do not invoke the software update command without reading
that document.
