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 <LF>, EOI, or both when sending commands to the receiver
via the GPIB. No characters are permitted after <LF> or EOI; the system
interprets characters following <LF> 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, <LF> 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.
