CES SDI-50 - Programming the Model SDI-50; 6.1 Entering the Program Mode

C.E.S. Model SDI-50 Manual, Level Adjustments
PROGRAMMING THE MODEL SDI-50
It is not necessary to program every parameter in the Model SDI-50 to
get your interconnect properly set up and tested. In that interest two
short programming procedures are listed for simplex and half/full
duplex operation in the section which follows. It is suggested that
you select and follow the appropriate required procedures for your
application, then review the factory default values for optional
program changes. Detailed instructions for the programming parameters
can be found in the next section.
The SDI-50 can be programmed remotely through the telephone line or
locally through the front panel with the use of the handheld DTMF
encoder provided. In either case, the programming sequence is
identical, and only the method by which programming access is obtained
differs.
The Program Summary Table lists all of the programmable features of
the Model SDI-50 interconnect. All of the features have factory
programmed values which are listed in the center column.

ENTERING THE PROGRAM MODE
The program mode may be entered in one of two ways:
Local Programming Mode - With the supplied DTMF tone pad plugged
into the front of the interconnect, dial "O", then press the
connect button on the SDI-50 within five seconds. The SDI-50
will respond with a beep tone indicating that it is in the
programming mode. (In order to hear response tones when locally
programming the SDI-50, you will need to have a service monitor
or receiver tuned to the transmit frequency).
NOTE: Because the SDI-50 is constantly monitoring receive
audio for DTMF tones, it is possible that DTMF tones
received from Rx audio may interfere with programming in
the local programming mode. If the receiver is turned on,
temporarily remove jumper JMP6 during programming to keep
the SDI-50 from recognizing these tones.
Remote Programming Mode - The SDI-50 must have Auto Answer
enabled to use this feature. Dial the telephone number of the
line connected to the interconnect. When the interconnect
answers, it will send two quick beep tones to the phone line.
Enter the Remote Programming Code followed by a "#". If the
correct code is entered, the SDI-50 will
