48 | Remote Operation
IEEE-488 (GPIB) Communications
For General Purpose Interface Bus (GPIB) communications, the End or
Identify (EOI) control line may also be used for command termination. Terminate
the command with , EOI, or both when sending commands to the receiver
via the GPIB. No characters are permitted after or EOI; the system
interprets characters following or EOI as the start of another command.
When an error condition is present at the receiver, the service request (SRQ)
signal is asserted. The operator can then perform a serial poll operation. The
receiver error code (in binary) is contained in the lower bits of the serial poll
status byte. If the receiver is addressed as a listener and the GPIB remote line is
asserted, the receiver will switch to remote mode.
RS-232 Communications
Commands are processed in a manner very similar to that of the IEEE interface.
The command structure is identical, except that an EOI line does not exist;
therefore, must terminate all commands. When a valid command is
received, it is processed and the result is immediately transmitted back over the
RS-232 interface. The output format is identical to that of the IEEE format except,
again, an EOI line does not exist.
