REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 T1 or E1 shelf, the RFL VF-6I module can be operated under local
or remote control. When under remote control, most of the module setup parameters can only be
changed through the RS-232 remote port on the shelf Common Modules. See the IMUX 2000 manual
for details on the remote control interface.
“P” CODES AND “S” CODES
The RFL VF-6I reports itself as a “Type 121” 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 the 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-6I response to a “CONFIG?” query looks like this:
* OK
CHANNEL CARD 3, TYPE 121
UNDER REMOTE CONTROL
SVCE = ON
P01 = 10 (B00001010)
P02 = 0 (B00000000);
Each “P” code is displayed in both decimal and binary representation, however, the binary
representation is generally more useful, as each of the eight digits corresponds to a specific switch or
jumper on the module. Table 5 lists the meaning of the “P” codes for the RFL VF-6I.
