OEM users of the 4809A, 4819A, 4829A and 4899A should provide the
end user with the necessary instructions to operate the complete system.
In most cases this includes directions for:
1. Setting the product’s GPIB Address or serial address.
2. How to use the Modbus commands to control the host device.
(Includes sending outputs and reading inputs if applicable). The
OEM needs to define the commands in terms of what they do to
the host unit and how the end user should use them.
3. Using the 488.2 Status Reporting Structure. The OEM needs to
define what the digital inputs mean if they are part of the system,
how to enable SRQs and how to read the registers.
The SCPI Standard requires that the SCPI command tree and SCPI con-
formance information be passed on to the end user. This only means the
active or applicable commands. Locked commands become invisible to
the end user and should be omitted from the end user’s SCPI command
tree and list.

bidden.
