OSMAC RDR Retrofit Narrow Band Decoder Module, Part No. 102-2012
Installation Guide
Introduction
The RDR retrofit decoder module was developed to allow existing wide-band UHF radio frequency users to migrate
into narrow band frequencies. The following instructions assume the RDR retrofit module has been programmed with
a licensed frequency or will use one of the four pre-programmed frequencies available while awaiting confirmation of a
licensed frequency.
Note: It is the end-user's responsibility to apply for a new narrow band frequency license or update the current license
on file with the FCC as part of the retrofit process.
Procedure
Step 1: Locate the RDR decoder module and remove the black ground
wire to disconnect power to the module. After power is dis-
connected, continue to remove the orange 12 V a.c. power
wire, red 26 V a.c. power wire and the flat ribbon cable.
Remove all wires connected from the terminal block of the
decoder module and note their position for rewiring. See
Figure 1.
CAUTION: Potential damage can occur to the RDR decod-
er module components if power is not shut off by detach-
ing the ground wire first.
Step 2: Remove the decoder module by pulling it straight out.
Step 3: Select the desired operating channel frequency on the RDR
retrofit module by placing the jumper on the appropriate pin
set. See Figure 2.
The pre-programmed frequencies are as follows:
Channel 1
Channel 2
Channel 3
Channel 4
Note: These frequencies are not Toro licensed and does not imply
that they are usable in any application. Obtaining a narrow
band frequency is the responsibility of the end-user.
Each of the four frequencies is programmable using kit P/N
102-1208 for 120 V a.c. or P/N 102-1230 for 240 V a.c.
Step 4: Set the address code of the RDR retrofit decoder module to
match the address code on the decoder card removed. See
Figure 3. The number 1 DIP-switch is the least significant bit.
This is opposite to the Wide Band decoder module DIP-switch
settings. Refer to the Address Code Table on the back page.
Step 5: Carefully place the RDR retrofit decoder module into the
cabinet. Do not force it into position.
