REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 shelf, the RFL VF-5A module can be operated under local or remote
control. When under remote control, most of the module set-up parameters can only be changed
through the RS-232 remote port on the shelf Common Modules. See your IMUX 2000 instruction
manual for details on using the remote control interface.
"P" CODES AND "S" CODES
The RFL VF-5A reports itself as a "Type 64" module. Its remote control interface involves two sets of
codes: "P"(parameter) codes, and "S" (status) codes.
"P" codes, when used in the parameter field on an "SCL SET" command, allow the user to set certain
parameters on the module by remote control, just like setting the switches on a module under local
control. "P" codes also appear in the response to a "CONFIG?" query, providing a list of the current
settings on the module. A typical RFL VF-5A response to a "CONFIG?" query looks like this:
*OK
CHANNEL CARD 3, TYPE 64
UNDER REMOTE CONTROL
SRVC = ON
P01 = 10 (B00001010)
P02 = 0 (B00000000)
P03 = 1 (B00000001)
P04 = 1 (B00000001);
Each "P" code is displayed in both decimal and binary representation. Table 5 lists the meaning of the
"P" codes for the RFL VF-5A
