Overview and Identication

The BAPI 900 MHz unit receives a repeated or re-transmitted RF signal from one

or more wireless temperature or humidity transmitters. The signal from the transmitter

(418 MHz) is received by a BAPI Repeater and then re-transmitted at 900 MHz up to

1,000 feet to the 900 MHz Receiver.

The receiver then outputs the values to any Analog Output Module through an RS485

four-wire bus. The Analog Output Modules convert the signal to an analog voltage,

current or resistance for the controller. The receiver can accommodate up to 127

different Analog Output Modules. It is surface, snaptrack or DIN rail mountable with a

79” extendable antenna for optimum recep-

tion.

Note: The 900 MHz Receiver will only

receive a signal from a Repeater. It will not

receive the signal from the transmitters,

which transmit at 418 MHz.

Analog Output Module Training

The installation process requires that each transmitter is trained to

its associated output module or modules so that they receive com-

munications from the correct transmitter. Pushing buttons in a de-

ned sequence on the transmitter and output module will bind the

two units together. The training process is easiest on a test bench

so that the transmitter and receiver/output modules are within

arm’s reach of each other. Training can be done in the eld but will

require two people and a set of walkie talkies or cell phones. Be

sure to place a unique identication mark on the transmitter and

associated output module or modules after they have been trained

so that they can be matched together at the job site.

If more than one variable is transmitted by the room transmitter

(temperature, humidity and setpoint for instance), each variable

requires a separate output module. Perform the training sequence

for each output module. Any transmitted variable can be trained to

more than one output module.

TEMPERATURE OR HUMIDITY VARIABLE TRAINING

1. To train an output module to a Temperature or Humidity

variable, select the Resistance, Voltage or Current Output Module calibrated to the

temperature or humidity range you need and connect it to the wireless receiver. Note:

Multiple output modules can be trained to the same transmitter variable if desired.

2. Apply power to the receiver which will supply power to the connected output modules.

The power LED on the receiver will light and remain lit. (Current Output Modules

must have loop power supplied to the module itself before they can be trained.)

3. Remove the cover of the room transmitter and remove the battery tabs or install the

batteries, observing polarity as shown in Fig 2. The small LED at the bottom right of

the circuit board, next to the setpoint, will ash approximately once every 20 seconds,

indicating a transmission. (The ash is very quick.)

4. Press and hold down the “Service Button” on the top of the output module (Fig 3) that you wish to train. Then, press

and release the “training button” (see Fig 2) on the room transmitter. When the output module receives the “training

transmission” from the room transmitter, the output module’s red LED will light. Release the “Service Button” on the

output module and the red LED will go out. The transmitter and output module are now trained to each other. During

normal operation, the output module’s LED will ash about once every 20 seconds indicating data reception from the

transmitter trained to it.

Note: The room transmitter sends both the temperature and humidity information when the “Training Button” is

pressed. However, each Analog Output Module is congured at the time of order as a temperature, humidity,

Setpoint or Override module and will only recognize the relevant information and will ignore the rest.

5. Mount the transmitter at the desired location. If needed, remove the batteries to do so. The units will remain trained

to one another through power failures and battery replacement. Replace the transmitter’s cover and back out the

security screws.

SETPOINT VARIABLE TRAINING

1. To train an output module to a Setpoint variable, select the Setpoint Output Module (SOM) calibrated to the setpoint

range you need and connect it to the wireless receiver. Note: Multiple output modules can be trained to the same

transmitter variable if desired.

2. Apply power to the receiver which will supply power to the connected output modules. The power LED on the

Receiver will light and remain lit. (Setpoint Output Modules with current output must have loop power supplied

to the module itself before they can be trained.)

3. Remove the cover of the room transmitter and remove the battery tabs or install the batteries, observing polarity as

shown in Fig 2. The small LED at the bottom right of the circuit board, next to the setpoint, will ash approximately

once every 20 seconds, indicating a transmission. (The ash is very quick.)

4. Press and hold down the “Service Button” on the top of the output module (Fig 3). Then, press and release the

OVERRIDE button on the transmitter (See Fig 2). (Note: If the unit was not ordered with an override function, then

the OVERRIDE button will be shorter and will not extend outside the case but will still be accessible upon removing

the cover.) When the output module receives the “Training Setpoint” info from the transmitter, the output module’s red

LED will light. Release the “Service Button” on the output module and the red LED will go out. The transmitter and

output module are now trained to each other. During normal operation, the output module’s LED will ash about once

every 20 seconds indicating data reception from the transmitter trained to it.

5. Mount the transmitter at the desired location. If needed, remove the batteries to do so. The units will remain trained

to one another through power failures and battery replacement. Replace the transmitter’s cover and back out the

security screws

Mounting and Locating of the 900 MHz Antenna

The 900 MHZ Receiver comes with the “Whip” Antenna but a

900 MHz Extendable Dipole Antenna is also available.

The receiver may be located inside a metal enclosure but the

antenna must be outside the enclosure. The “Whip” Antenna

simply screws onto the receiver. Mounting the receiver and

antenna on a metal surface may block reception from behind the

surface and frosted windows may block reception too.

For the Extentable Dipole Antenna, peal off the protective

lm from the adhesive pad and stick the antenna to a wall or

other non-metallic support. Mounting the antenna on a metal

surface may block reception from behind the surface and

frosted windows may block reception too. A wooden or plastic

furring strip attached to a ceiling beam makes a great mount.

The antenna may be hung from any ceiling xture using ber or

plastic twine. Do not use wire to hang, and do not use perforated

metal strapping, commonly called plumbers tape.

The Wireless Receiver and Analog Output Modules can be mounted in snap

track, DIN Rail or surface mounted.

SNAPTRACK MOUNTING

Push in the blue mounting tabs on the receiver and output modules. These

units will now t into the board slots of 2.75” snap track. Insert the receiver at

the far left of the snap track, then insert each analog output module and slide

it to the left until its connectors are fully mated into the receiver or the next

analog output module. You may attach up to 127 analog output modules to a

receiver.

If your output modules cannot t in one piece of snap track, then mount

another piece of snap track nearby and insert your additional modules.

Connect wires from the right side of the rst string of modules to the left side

of the second string of modules on the second snap track. This conguration

requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-

CONN) for the extra wire terminations on the left and right side of the Analog

Output Modules. Each kit includes 4 connectors.

DIN RAIL MOUNTING

Push out the blue mounting tabs on the receiver and

output modules. These units will now snap onto DIN

Rail. Catch the EZ mount hook on the edge of the

DIN rail as shown in Figure 6. The rotate into place.

Attach the receiver at the far left of the DIN Rail,

then attach each analog output module and slide it

to the left until its connectors are fully mated into the

receiver or the next analog output module. You may

attach up to 127 analog output modules to a receiver.

If your output modules cannot t onto one piece

of DIN Rail, then mount another piece nearby and

attach your additional modules. Connect wires

from the right side of the rst string of modules to the left side of the second string of modules on the second DIN Rail. This

conguration requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN) for the extra wire terminations

on the left and right side of the Analog Output Modules. Each kit includes 4 connectors.

SURFACE MOUNTING

Push out the blue mounting tabs on the receiver and output modules. Attach the

receiver to the surface using four screws, one in each blue tab. Attach Analog Output

Modules by placing each one against the surface and sliding it to the left until its

connectors are fully mated into the receiver or the next analog output module. Attach

each module to the surface with two screws, one in each blue tab. You may attach

up to 127 analog output modules to a receiver.

If your output modules cannot t in one straight line on the surface, then mount a

second string of modules nearby. Connect wires from the right side of the rst string

of modules to the left side of

the second string of modules.

This conguration requires one

or more Pluggable Terminal

Block Connector Kits (BA/AOM-CONN) for the extra wire terminations

on the left and right side of the Analog Output Modules. Each kit

includes 4 connectors.

1. The wireless receiver and Analog Output Modules are interconnected and require module power along the “Power

Bus” terminals. The bus can be powered from either the receiver end on the left or the last output module on the right

side. Be sure you have enough DC current or AC VA for all the devices on the bus.

2. The Current Output Module (BA/COM) signal is LOOP POWERED and must be externally powered with

9-36 VDC separate from the Power Bus. The Loop Power must be connected to Current Output Module before

it can be trained.

3. Be sure to follow the polarity (+ or –) symbols listed on each receiver and the output modules to maintain

communication and Power Bus integrity.

Extending the RS485 Network between the Receiver and the Analog Output Modules

The Analog Output Modules may be mounted up to 4,000 feet away from the receiver. The total length of all the shielded,

twisted pair cables shown in Fig. 9 is 4,000 feet (1,220 meters). Connect the terminals together as shown in Fig. 9. If the

distance from the receiver to the group of Analog Output Modules is greater than 100 feet (30 meters), provide a separate

power supply for that group of Analog Output Modules. BAPI’s VC350A EZ Voltage Converter and a small transformer

can be used to power

the group of Analog

Output Modules.

Wireless System Diagnostics

Possible Solutions:

- Check for proper wiring and connections from the output modules to the controller.

- Check to see if the controller’s software is congured properly.

- Check the room transmitter to see if its LED ashes about every 20 seconds. If

not, replace the batteries.

- Check for proper power to the Repeater, Receiver and Analog Output Modules.

- Retrain the Analog Output Module.

- Check that the associated room transmitter is transmitting (the LED will ash

about once every 20 seconds) and that the Repeater and the 900 MHz Receiver

are receiving the transmissions. (The Repeater’s LED will blink right after the

transmitter’s LED if it receives that transmission. The 900 MHz Receiver LED

will blink right after the Repeater’s LED if it is receiving that transmission.)

Note: The Repeater will receiver transmissions from all transmitters that are

within range, not just the one you are testing

- Retrain the Analog Output Modules.

- Check for proper wiring and connections from the output modules to the controller.

- Check to see if the controller’s software is congured properly.

- Check to see if the correct output module is connected to the correct controller.

Default Status when wireless transmission is interrupted:

If an output module does not receive data from its assigned transmitter for 15 minutes, the red LED on the top of the

module will blink rapidly. If this happens, the individual Analog Output Modules will react as follows:

• Resistance Output Modules (BA/ROM) calibrated for temperature will output the highest resistance in their output range.

• Voltage Output Modules (BA/VOM) calibrated for temperature will set their output to 0 volts.

• Current Output Modules (BA/COM) calibrated for temperature will set their output to 4 mA.

• Voltage Output Modules (BA/VOM) calibrated for humidity will set their output to their highest voltage (5 or 10 volts).

• Current Output Modules (BA/COM) calibrated for humidity will set their output to 20 mA.

• Setpoint Output Modules (BA/SOM) will hold their last value indenitely.

• Relay Output Modules (BA/RYOM, BA/RYOL) will go to their default state (example: open for a normally open unit).

When a transmission is received, the output modules will revert to normal operation in 60 seconds or less.

Possible Problems:
