This chapter is divided into three parts. The first part contains information for
getting started using GPIB. It also contains the syntax for each 488.2 common
command which is supported by the 6810B. The second part contains information
on status reporting and advanced programming techniques. The third part
contains information on remote interface messages which are generally
transparent to the user.
Preparation for GPIB Control
To use the OMM-6810B remotely, an IEEE 488 interface adapter is required in
your host computer. These adapters and support software are available from
several manufacturers and can be installed in most computers. Appendix C
describes how to configure many of these interface adapters for use with the
6810B. This Chapter and Chapter 4 assume that you have a basic knowledge of
the IEEE 488 interface bus and how to use it for instrument control. You should
also be familiar with front panel operation of the OMM-6810B. Manual operation
is detailed in Chapter 2.
GPIB Control
Sending any command over the GPIB bus automatically puts the instrument in
REMOTE mode. The REMOTE indicator identifies when the instrument is in
remote operation mode. When the instrument is in REMOTE mode, pressing the
LOCAL switch returns the instrument to lOCAL control mode unless a Local
Lockout state has been activated by the low level GPIB command LLO from the
host computer. Local Lockout disables all LDC-3900 front panel switches until this
condition is changed by the host computer. In this condition, the REMOTE
indicator will flash at a 1 Hz rate.
For more information on low level interface commands such as LLO, refer to the
IEEE488.1 specification.
GPIB Address
The talk and listen addresses on the OMM-6810B are identical. When the unit is
in LOCAL mode, pressing the LOCAL button causes the GPIB address to be
displayed. Extended GPIB addressing is not implemented in the 6810B. Use the
following procedure to change the GPIB address.

Preparation for GPIB Control
Press and release the LOCAL button. If the current GPIB address is not on the left
display, press and release LOCAL again.
While the GPIB address is displayed, press the POWER UP or DOWN buttons to change
the address. The usable range is 0 to 30.
