BN-Series
General Features
The BN-35I is a low cost pin for pin functional replacement for the Newport model 215, with many more features. It is a 312 digit voltmeter in a compact 96x24mm case with an internal isolated power supply. 5V, 12V, 15V or 24VDC power options are available.The case has a short depth of just 2.83 inches (72mm) behind the panel.
The meter has four user-selectable ranges of 200mV, 2V, 20V and 200V. The BN-35I may also be calibrated at the factory for these ranges or specially scaled for other ranges (see Ordering Information below). Provision to offset the zero is also available as an option for 4-20mA signals.
The display is shipped standard with red LEDs, but green LEDs or super bright LEDs for high ambient light environments are also offered. Display Segment Test, Display Blank and Hold Reading are standard features.
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.

The Texmate model BN-35I interconnects by means of a standard PC board edge connector having two rows of 15 pins, spaced on 0.156" centers. Texmate also offers a Push-On screw terminal connector that provides a great advantage in ease-ofuse (see pg. four). Connectors are available from Texmate.
Rear View of Meter
Pins 1 & A - Positive DC Power Input: These pins are internally connected together. The positive end of the DC power is connected to these pins. The standard BN-35I meter is designed to be powered from a 24VDC power supply. Optional 5V, 12V, or 15VDC powered models are also available. Before using the meter, make sure that the appropriate power is being applied. The BN-35I meter generates a 5V supply internally that is isolated from the applied DC power.
Pins 2 & B - Hold Reading: These pins are internally connected together. If these pins are left unconnected, the meter will operate in a free-running mode. When this pin is connected to the Hold/Test/Blank Common Pin 7, the meter will latch up. A/D conversions will continue, but the display will not be updated until Pins 2 & B are disconnected from Pin 7.
Pins 3, 4, C, and D - Negative DC Power Input: These pins are internally connected together. The negative end of the DC
power is connected to these pins. The standard BN-35I is designed to be powered from a 24VDC supply. Optional 5V, 12V, or 15VDC powered models are also available. Before using the meter, make sure that the appropriate power is being applied. The BN-35I meter generates a 5V supply internally that is isolated from the applied DC power.
Pin 6 - External Reference Input: See page three for operating the meter with an external reference, as a ratiometric voltmeter.
Pin 7 - Hold/Test/Blank Common Pin: The Display Hold/Test/Blank pins have to be connected to this pin to be activated.
Pin H - Display Blank/Dim: If this pin is connected to Pin 7, the display will be blanked out. If a 5K potentiometer is connected between this pin and Pin 7, the brightness of the display may be smoothly adjusted.
Pins 8 and J - Display Test: These pins are internally connected together. All numeric display segments will light up when this pin is connected to the Hold/Test Blank Common Pin 7.
Pins 9 and K - Signal High Input: These pins are internally connected together. Signal high input for the meter. The input voltage can range from200mV to 200VDC. By closing some solder jumpers, the user can change from one range to another. See page three for range change information.
Pins 10 and L - Signal Low Input: These pins are internally connected together. Signal low input of the A/D Converter.
Pins 11 and M - Reserved Pins: These pins have been reserved for future new functions. Please do not use them as tie points for external wiring, as they are connected to internal circuit points.
Pins 12 & N, 13 & P and 14 & R - Decimal Points: These are the decimal point pins. Connecting any of these pins to the Decimal Select Common Pin makes that particular decimal point come on.
Pins 15 and S - Decimal Select Common: These pins are internally connected together. The decimal point pins must be connected to this pin to come on.

ZERO Potentiometer (Pot)
The Optional ZERO pot when installed is always to the left of the SPAN pot (as viewed from the front of the meter). Typically it enables the displayed reading to be offset 1000 counts.
Unscrew the knurled collars, and remove the mounting clips.
Snap out the rear plastic plate. The BN-35 printed circuit board can then be easily removed by sliding it out from the rear of the case.
SPAN Potentiometer (Pot)
They provide the greatest convenience and ease of use Texmates exclusive optional Push-On Connectors combine an edge card connector and a 10 position screw terminal block. Push-On Connectors are ordered preconfigured for each specific power supply voltage and each optional power supply available for the UM-Series.
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-35 meter. Order part no. CN-L15.
The 15 turn SPAN pot is always on the right side (as viewed from the front of the meter). Typical adjustment is 20% of the input signal range.
Changing the range to 200mV, 20V or 200V. The BN-35I 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.

The BN-35I is calibrated at the factory with a precision source.
Whenever the range is changed, the meter needs to be recalibrated. The Span Pot 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 Pot in the front of the meter so that the displayed reading agrees with the signal input.
5. The BN-35I is now calibrated and ready for use.
The BN-35I ships from the factory with an internally isolated 24VDC power supply. For applications where isolation between the power and signal grounds is not required, use the lower cost Texmate model BN-35. The BN-35 is powered from a non-isolated 5VDC power supply.
To customize the front bezel, each DU-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.
