RS-232 Source Type Command L
Parameters:
XXX
$LXXX
The first parameter (X) is the source type and will have a range of 0
through 7. As list in Figure 3.3 for the configuration switch, 0 will select a four pocket
and 7 will select a 3 pocket 145 degree banana. The second parameter (X) is the
uni-bi-directional switch. A zero for this parameter will select unidirectional and a 1
bi-directional. The third parameter (X) will select the rotation direction. A zero will
select counter-clockwise and a 1 will select clockwise.
Example
$L501
Selects a three pocket 120 degree
banana,
uni-directional,
clockwise
source.
It is also possible to query this parameter and obtain the current definition of the
above three parameters. The query command will be $L?
If the user has never sent a valid “L” command to change the source type, and you
query the status with an “L?
the unit functioning as initially set by the DIP switches. If you send a valid “L”
command changing any of these parameters, all subsequent queries will respond
with the current setting as set by the previous “L” command.
When you send an “L” command the unit will reconfigure the source type and then
immediately search for the home index pulse. This was implemented because the
Indexer may not be at a valid pocket once reconfigured and there was a possibility of
sending a false Pocket Good indication signal. Searching for the index pulse will
prevent this from happening and the unit will then go pocket one.
