LACS S
4
The LACS bit specifies whether the GPIB-232CT has
been addressed as a Listener. The LACS bit is set
whenever the GPIB-232CT detects that its listen address
(and secondary address, if enabled) has been sent either
by the GPIB-232CT itself or by another Controller. The
LACS bit is also set whenever the GPIB-232CT shadow
handshakes as a result of the
gts
function. The LACS
bit is cleared whenever the GPIB-232CT detects that the
Unlisten (UNL) command, its own talk address, Interface
Clear (IFC), or
gts
is called without shadow handshake.
DTAS S
2
The DTAS bit specifies whether the GPIB-232CT has
detected a device trigger command. The DTAS bit is set
whenever the GPIB-232CT as a Listener, detects the
Group Execute Trigger (GET) command has been sent by
another Controller. The DTAS bit is cleared in status at
the start of any subsequent programming message.
DCAS S
1
The DCAS bit specifies whether the GPIB-232CT has
detected a device clear command. The DCAS bit is set
whenever the GPIB-232CT detects the Device Clear
(DCL) command has been sent by itself or by another
Controller, or whenever the GPIB-232CT as a Listener
detects the Selected Device Clear (SDC) command has
been sent by itself or by another Controller. The DCAS
bit is cleared in status at the start of any subsequent
programming message.
