BN-Series
General Features
The BN-40BCD is a 4 digit remote or slave BCD display that is popularly used to display the BCD output from a PLC system.
For applications where a polarity sign is required the 3 1/2 digit BN-35BCD may be used. The BN-40 BCD and BN-35 BCD are ideal solutions for low cost operator interfaces.
Both BN-40BCD and BN-35 BCD are powered from 5V DC.
They are shipped standard with Red LEDs, but green LEDs or super bright LEDs for high ambient light conditions are also offered.
BN-40BCD with parallel BCD input.
The BN-Series have a matching DIN case style that is complementary to the Lynx, Leopard and Tiger family of meters. BN-Meters are the OEMs choice for economical switchboard and process indication. For economy, each model is dedicated to a specific application and designed for quick and easy installation.

Pins A, C, E and H are the B1, B2, B4 and B8 bits of Digit 3 respectively. +5V on these lines corresponds to a High Level (1), and 0V on these lines corresponds to a Lo Level (0).
Pin B, D, F and J are the B1,B2, B4 and B8 bit of the MSD Digit 4. +5V on this line corresponds to a High Level (1), and 0V on this line corresponds to a Lo Level (0).
Pins 9, K, 10 and L are the Read Data lines for the Digit 1, Digit 2, Digit 3 and Digit 4 data respectively. Data is read into the meter whenever the corresponding Read Data line is at +5V (Hi Level).
Pins 11, 12 and 13 are the Decimal Point Inputs to the meter.
They correspond to Decimal 1, 2 and 3 respectively. When any of these pins is at a +5V (Hi Level) the corresponding Decimal is turned ON.
Pin P is the Display Dim or External Brightness Pin. If an external potentiometer (approx 500) is connected between Pin P and Pin S, the brightness of the display can be adjusted. If no adjustment is required Pin P should be directly connected to Power Ground Pin S.
Pin 14 is the Display Blank Pin. If Pin 15 is directly connected to Pin S, all segments of the display are turned OFF. This feature is used to conserve power in push to read applications.
Pin 15 is the Display Test Pin. If Pin 14 is directly connected to Pin S, all segments of the display come on. This is a useful feature to test for missing segments.
Pin R is the +5V DC Power Pin. The current required is approx 200mA.
Pin S is the 0V Power Ground Pin.
The Texmate model BN-40BCD interconnects by means of a standard PC board edge connector having two rows of 15 pins, spaced on 0.156" centers. Connectors are available from Texmate.

Pins 1, 3, 5 and 7 are the B1, B2, B4 and B8 bits of the LSD Digit 1 respectively. +5V on these lines corresponds to a High Level (1), and 0V on these lines corresponds to a Lo Level (0).
Pins 2, 4, 6 and 8 are the B1, B2, B4 and B8 bits of Digit 2 respectively. +5V on these lines corresponds to a High Level (1), and 0V on these lines corresponds to a Lo Level (0).

Changing the range to 200mV, 20V or 200V. The BN-40BCD comes standard as a 2VDC meter. The factory can recalibrate the meter to a different range either when the meter is ordered or as an after sale service using part number VRC-DPM.
For the user to change the range, closing of some jumpers by soldering and opening other jumpers is required. Follow the chart below to achieve the required range. See the above component layout to find location of jumpers. Remember to recalibrate the meter after every range change.

Calibration Procedure
The BN-40BCD is calibrated at the factory with a precision DC voltage source. Whenever the range is changed, the meter needs to be recalibrated. The Span Potentiometer is accessible with the front cover of the meter removed for user calibration.
1. Make sure there is proper DC power and input.
2. Connect the power supply.
3. Apply a positive signal input equal to 95% of the full scale
input.
4. Adjust Span Potentiometer in the front of the meter so that
the displayed reading agrees with the signal input.
5. The BN-40BCD is now calibrated and ready for use.
Unscrew the knurled collars, and remove the mounting clips.
Snap out the rear plastic plate. The BN-40BCD printed circuit board can then be easily removed by sliding it out from the rear of the case.
The BN-40BCD ships from the factory with a non-isolated 5VDC power supply. For applications where isolation is required between the power and signal grounds, use the Texmate model BN-35-ISO. This model is available with 5V, 12V, 15V, and 24V power options and generates an internally isolated supply.
To customize the front bezel, each BN-meter is supplied with a white printed clear adhesive label containing popular
descriptors. Choose the descriptor desired, peel off the adhesive backing and align the descriptor in the center right of the faceplate.

PCB Edge Connector
A standard 30-pin edge connector (two rows of 15 pins on 0.156" centers) may be used to connect the BN-40BCD meter.
