The BAPI 900 MHz unit receives a repeated or retransmitted RF signal from one or more wireless temperature or
humidity transmitters. The transmitter signal (418 MHz) is received by a BAPI Repeater and then re - transmitted at
900 MHz up to 1,000 fe et to the 900 MHz Receiver.
The 900 MHz Receiver then outputs the values to any Analog Output Module through an RS485 four -wire bus. The
output module converts the signal to an analog voltage, current or resistance for the controller. The 900 MHz
Receiver can accommodate up to 127 different output modules. The receiver is surface, snaptrack or din rail
mountable with an attached antenna or a 79” extendable antenna.

1. Apply power to the receiver , repeater and output modules. (Note: Apply loop power to the current output module.)
2. The power LED on the Receiver should light and remain lit. The powered analog output module's LED should
flash and go out. (The flash is very quick.)
5. Remove the cover of the transmitter and install the batteries, observe polarity. The small LED at the bottom right,
next to the Transmi tter Traini ng Button , should flash approximately once every 10 seconds. (The flash is very
quick.)
6. Pick a transmitter and an analog output module you want to train to recognize one another. Press and hold the
plastic service button on the top of the Output Module, a t the same time press for one second and release the
button on the transmitter. When the LED on the output module lights, release its button (The LED will go out
when you release the button). The output module will now report the environmental conditions from the
transmitter trained to it. The output module's LED will quickly flash whenever it receives an update from the
transmitter.
7. Mount the transmitter at the desired location. If needed, remove the batteries to do so. The units will remain
trained t o one another through power failures and battery replacement.
8. Replace the transmitter's cover and back out the security screws.

There are several ways to mount the receiver. Connect a DC voltage of 9 to 15VDC to the receiver. Ma ke sure that the
Power Bus negative ( - ) is connected to the controller's analog ground.
Insert the BA/RCV900 into a piece of snaptrack. Insert into the snaptrack just to the right of the receiver an analog output
module, slide the modu le to the left until it's connectors are fully mated into the receiver. You may attach up to 127 analog
output modules by mating each new one into the analog output module on the end of the train. If you wish to connect
more output modules than room in y our snap track, place another piece of snap track nearby and connect wires from the
right end of the train to an analog output module on the left end of the second piece of snaptrack. Continue to place
additional analog output modules in the second piece of snaptrack to the right of the first additional analog output module
and sliding them into place.
DIN Rail mount
Clip a BA/RCV900 onto a piece of DIN Rail. Clip onto the DIN Rai l just to the right of the receiver an analog output
module, slide the module to the left until it's connectors are fully mated into the receiver. You may attach up to 127 analog
output modules by mating each new one into the analog output module on the e nd of the train. If you wish to connect
more output modules than room on your DIN Rail, place another piece of DIN Rail nearby and connect wires from the
right end of the train to an analog output module on the left end of the second piece of DIN Rail. C ontinue to place
additional analog output modules on the second piece of DIN Rail to the right of the first additional analog output module
and sliding them into place.

Mount Receiver Mount 1st Analog Output Module Mount 2nd Analog Output Module
Mount a BA/RCV900 to a surface with four screws as shown in Figure 6. Slide an analog output module onto the receiver
until it's connectors are fully mated into the receiver. Attach the analog output module to t he surface with two screws as
shown in figure 7. Slide additional analog output modules on the end as shown in Figure 8. Make sure to attach each
additional analog output module to the surface with two screws. The next module coves the previous one's sc rews, so
remember to drive the screws as you proceed.
You may attach up to 127 analog output modules by mating each new one into the analog output module on the end of
the train. If you wish to connect more output modules than can fit on your surface, pla ce additional analog output modules
nearby and connect wires from the right end of the train to the additional analog output module. Continue to place
additional analog output modules to the right of the first additional analog output module and sliding t hem into place.
Remember to screw the analog output modules in place as you go.

The Analog Output Modules may be mounted up to 4,000 Ft away from the receiver. The total length of all the shielded,
twisted pair cables shown in Figure 9 is 4000Feet (1220 meters). Connect the terminals together as shown in Figure 9. If
the distance from the receiver to the analog output module is greater than 100 Feet (30 meters ), provide a separate power
supply for the Analog Output Modules. BAPI BA/VC75 and a small transformer can be used to power the remote analog
output modules.
Temperature or Humidity is reading its

- Check to see if the controller's software is configured properly.
- Check transmitter to see if its LED flashes about every 10 seconds. If not replace the
batterie s.
- Check power to the receiver , repeater and output module s.
- Check output modules LED, if it is blinking fast
Check the associated transmitter as described above
Retrain the modules
