ALERTS/ALARMS
The RFL DA-121I module reports no module level ALERT or ALARM signals to the shelf Common
Module.
REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 remote controllable shelf, the RFL DA-121I module can be operated
under local or remote control. When under remote control, certain configuration parameters can only
be changed through the RS-232 remote port on the multiplexer. The remote interface for these modules
involves two codes: a “P” (parameter) code, and an “S” (status) code. See the IMUX 2000 instruction
manual for more information on the remote control interface.
The RFL DA-121I reports itself as a “Type 127” module when installed in a T1 or E1 system.
“P” CODES
“P” codes, when used in the parameter field on a “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, showing the current parameter
settings on the module.
There are two “P” codes for the RFL DA-121I when operated in a T1 or E1 system: P1 and P2. Each
of these P codes can be a decimal number from 0 to 255, which can also be represented as an eight-
digit binary number (in parenthesis). The binary representation is more useful for setting and
interpreting the “P” codes, since each binary digit (0 or 1) corresponds to the ON or OFF setting for a
particular switch on the module. Table 4 describes the meanings of the “P” codes for the RFL DA-
121I.
A typical RFL DA-121I response to a “CONFIG?” query of a T1 or E1 system looks like this:
* OK
CHANNEL CARD 3, TYPE 127
UNDER REMOTE CONTROL
SVCE = ON
P01 = 3 (B00000011)
P02 = 1 (B00000001);
NOTE
When using binary numbers with a SET command, they must be preceded by the letter “B” as
shown in the following example:
<MULTIPLEXER ADDRESS>:<CARD ADDRESS>:SET:P1 = B00000011;
Besides using the P code, it is also possible to turn module service on or off by sending one of the
following in the parameter field with a SET command:
SRVC = ON
SRVC = OFF
