REMOTE CONTROL INTERFACE
When the RFL DS-961D module is installed in an IMUX 2000 multiplexer, it 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 Module. See the IMUX 2000 manual
for information on using the remote control interface.
The remote control interface for the RFL DS-961D involves two sets of codes: “P” (parameter) codes,
and “S” (status) codes. The RFL DS-961D reports itself as a “Type 68” module.
“P” CODES
“P” codes, when used in the parameter field of an SCL “SET” command, allow the user to set certain
parameters on the RFL DS-961D by remote control, just like setting the DIP switches on a module
under local control. “P” codes also appear in the response to a “CONFIG?” query, providing a list of
the RFL DS-961D’s current parameter settings. A typical RFL DS-961D response to a “CONFIG?”
query looks like this:
Response: This line means:
* OK
CHANNEL CARD 3, TYPE 68
UNDER REMOTE CONTROL
SRVC = ON
P01 = 4 (B00000100)
P02 = 0 (B00000000)
P03 = 2 (B00000010)
P04 = 1 (B00000001)
P05 = 0 (B00000000)
P06 = 1 (B00000001)
P07 = 1 (B00000001)
P08 = 0 (B00000000)
P09 = 0 (B00000000)
P10 = 0 (B00000000)
P11 = 0 (B00000000);

There are eleven “P” codes for the DS-961D, “P1” through “P11”. Each “P” code is displayed as a
decimal number from 0 to 255, followed by an eight-digit binary equivalent in parentheses. The
decimal display is generally more useful for both setting and interpreting most of the “P” codes. For
example, P1 sets the time slot the module will use. To set the module to use time slot 9, issue a SET
command in the format:
<multiplexer address>:<card address>:SET:P1 = 9;
The binary value may be used if desired.
