Serial Poll Procedure

When serial poll procedure is initiated, a device is addressed to talk and

Active Controller sends Serial Poll Enable command (ATN line is low, because

addresses and GPIB command bytes are transferred over the interface).

The addressed device sends back to Active Controller a Status Byte (ATN line

is high, because data bytes are transferred over the interface).

Then, the Active Controller sends Serial Poll Disable command (ATN line is

low, because address and command bytes are transferred over the interface) to

end the serial poll sequence.

In order to obtain Status Byte from each device from bus, Active Controller

addresses the devices one by one.

Status Byte of each device must be analyzed. This makes serial poll procedure

to be relatively slow for large systems.

Interrogative Commands Over GPIB Interface

After receiving an interrogative command, when the response is ready to be

read, Message Available Bit (bit 4 of Status Byte Register) is set. Serial Poll

Enable command can be sent to read Status Byte.

Any other ommand (except Seria l Poll) clears the output buffer and the

response to the previous interrogative command is lost. In this case an error is

generated by the power supply ( Err -410, Query interrupted ) and MAV bit is

cleared.

In order to read the response to the previous interrogative command, the power

supply must be addressed as a Talker.

After the response is sent MAV bit is cleared.

MAV bit is also set when the power supply receives a command and it is not

able to execute it. Err -365, Timeout error message will be available in the

output buffer of the power supply.

When MAV bit is set, the power supply has a message to transmit to the Active

Controller. The power supply has to be addressed as a Talker in order to be able

to transmit the message.
