IF YOUR UNIT WAS NOT ORDERED WITH
MULTIBOX DO NOT ATTEMPT TO PRO-
GRAM MULTIBOX IN THE FIELD. TELE-
MOTIVE MUST COORDINATE ACCESS
CODE ASSIGNMENTS WITH THE TRANS-
MITTERS PRIOR TO ENABLING MULTI-
BOX. PLEASE CONTACT TELEMOTIVE IF
YOU NEED TO ADD MULTIBOX. FAILURE
TO FOLLOW THIS WARNING COULD
RESULT IN SERIOUS INJURY OR DEATH
AND DAMAGE TO EQUIPMENT.
WARNING
IF YOUR UNIT HAS MULTIBOX DO NOT
ATTEMPT TO PROGRAM ADDITIONAL
TRANSMITTERS IN THE FIELD. TELEMO-
TIVE MUST COORDINATE ACCESS CODE
ASSIGNMENTS WITH THE NEW TRANS-
MITTERS PRIOR TO EXPANDING MULTI-
BOX. PLEASE CONTACT TELEMOTIVE IF
YOU NEED TO ADD ADDITIONAL
TRANSMITTERS. FAILURE TO FOLLOW
THIS WARNING COULD RESULT IN SERI-
OUS INJURY OR DEATH AND DAMAGE TO
EQUIPMENT.
The TR12 has Multibox capability that allows up
to 8 transmitters to access a single system. Only
one transmitter may control the receiver(s) at a
given time. Access is on a first come first serve
basis. Once a transmitter has gained control,
another transmitter may not access the
receiver(s) until the controlling transmitter
relinquishes control by transmitting an OFF
command to the receiver(s) or the receiver(s)
times out due to inactivity.
The first transmitter to send an ON command
after the receiver has been released will then gain
control of the receiver(s). The number of
transmitters (1-8) allowed to control the
receiver(s) is dip switch selectable on the
Receiver Board.
NOTE
THE DESIRED MULTIBOX TRANSMITTERS
MUST HAVE CONSECUTIVE ACCESS
CODES BEGINNING FROM THE FIRST
ACCESS CODE.
7-3.2. SW3 Switch Multibox Settings.
Dip switch settings on the Receiver Board
control the number of transmitters. This is done
by the Receiver Configuration Switch SW3 (dip
switch positions -1, -2 and -3). Different settings
are used for 2, 3, 4 and up to 8 transmitters. See
Table 7-1. Multibox Switch Settings for proper
Multibox settings.
The Receiver Configuration Switch, dip switch
SW3, is found on the Receiver Board. See Figure
8-1. Receiver Layout. On the transmitters
sequential access codes are required. These are
set on access code switch “A” positions “1”, “2”
and “3’ or more as required. The first transmitter
uses the same access code as the receiver. The
other transmitters have the there access code
sequentially incremented each by one extra bit.
With “A1” being the least significant bit. See
Figure 7-1. Access Code Settings.
For Membrane transmitters the Access code
positions A1-A2 can be accessed through the
battery compartment. The Pendant Transmitter
requires the back to be removed.
See Table 7-1. Multibox Switch Settings below
for appropriate settings for both the transmitters
and receiver(s).
