Status Inputs
Two input signals (Status A and Status B) can be used to monitor the
external device's condition. The Status signals are inputted thru the
Operational Register in the 4863's 488.2 Status Reporting Structure so that
changes to the status inputs can be used to generate a Service Request and
interrupt the Bus Controller. User programs Status Signal polarities,
monitor conditions and enables SRQ generation.
2.8.6
Output Data Strobe and Handshaking
The 4863/2363 pulses the Output Data Strobe after placing string data on
the data lines. The Output Data Strobe can also be pulsed by the :STRobe
command. If Listen handshaking is enabled, the Strobe line is only pulsed
when the Status A input is in its logic 1 state. Holding the Status A input
in the logic 0 state inhibits data transfer. User programs the Strobe polarity
and enables/disables Listen Handshaking.
2.8.7
Trigger Output
The 4863/2363 pulses the Trigger line when the 4863/2363 receives a valid
trigger command. User programs Trigger polarity. Use the Trigger output
to initiate external action.
2.8.8
Reset Output
The 4863/2363 pulses the Reset line at power turn-on or when the 4863/
2363 receives the 488.2 *RST command. Use the Reset output to initialize
an external device.
2.8.9
Clear Output
The 4863/2363 pulses the Clear line at power turn-on or when the 4863
receives the 488.1 Device Clear command. Use the Clear output to initialize
an external device's data registers.
2.8.9
Remote State Output
The 4863/2363 asserts the Remote State line when the 4863 enters the GPIB
remote state. Use the Remote State false output to enable front panel or local
