When a new, non-configured AXON/NEURO is connected to the same network as a Davicom Cortex it will be detected automatically and added as a Modbus expansion unit. Similar to adding a MEXM expansion device to the Davicom Cortex, users may also click the Detect button in the Davicom Cortex menu under Devices > AXON & NEURO. Make sure the IP address of the AXON or NEURO is visible to the Davicom Cortex so that it can detect it.

More details on this mode of operation will be provided soon.

The tables below show the different MODBUS register addresses for the 3 types of AXON units.

Getting Started

1- Remove the top cover of the NEURO unit using a Phillips-head screwdriver (7x screws). Put the screws aside (do not throw them out).

2- Unscrew the front panel (4x screws in the front, 2x screws underneath the unit) and put the screws aside (do not throw them out).

3- Disconnect the cable from the top right hand side of the front panel.

4- Disconnect the cable from the bottom right hand side of the front panel.

5- Pictured below is the numbered placement of the I/O cards in a NEURO. Most people with an existing NEURO should have at least one I/O card already installed, in addition to the Main card. You must install any additional NIO cards following the order of the numbers indicated (2 before 3, 3 before 4, etc.). Furthermore, it is recommended to install NIO-5R cards first, then NIO-8D cards, then NIO-8A cards. Regarding this, you can disregard the cards you already have pre-installed, e.g. if you already have a NIO-8A installed in your existing NEURO, do not uninstall it to install a new NIO-5R before it, simply stick to the order for the cards you are installing yourself.

Installing a new card in position 2

If you already have a NIO card installed in position 2, go to the next section.

Final Steps

1- Line up your front panel with your NEURO body and take note of the slots that correspond with NIO-8D and NIO-8A cards (cards with the blue DIP switches). Remove the stickers on the front panel for those slots. DO NOT remove stickers for the slots that correspond with NIO-5R cards or empty card slots.

2- Remove the metal punch-outs that are under the stickers you removed by gently twisting them by hand to break them loose. A pair of pliers may be used on the centerpiece being removed if needed. DO NOT remove the punch-outs for slots that correspond with NIO-5R cards or empty card slots.

3- Peel off the center cutout of the front labels as shown below. These labels are provided only with NIO-8D and NIO-8A cards. 

4- Carefully place these labels over the corresponding slots on the front panel as shown in the example below (8D stickers over the slots lined up with 8D cards, 8A stickers over the slots lined up with 8A cards).

5- Reattach the cable connected to the Main card to the front panel. Then reattach the cable connected to the back of the unit to the front panel. Make sure to connect the cables in the correct direction.

6- Screw on the front panel using the same screws that were put aside earlier. (4x screws in the front, 2x screws underneath the unit).

7- Place the labels on the pluggable terminal blocks. Cut off any excess.

8- Place the corresponding label on the back panel. Make sure to place the labels under the slot that matches the NIO card inside according to the table below.

	NIO-8D
	NIO-8A
	NIO-5R

9- Place the numbered stickers on the pluggable terminal blocks. The number on the terminal block should be on the same side as the number on the back panel of the NEURO when plugged in.

10- Plug in the terminal blocks.

11- Screw the top cover back into place using the same screws that were put aside earlier.

You have now completed the installation of your new NIO cards!

The post How to Install Extra NIO Cards into an Existing NEURO Unit appeared first on Davicom Exchange Support Portal (DEX).

System Set Up

1- Connect the transmitter end of the BPS to your transmitter.

2- Attach the antenna end of the BPS to either an inline power meter (to verify power output) or directly to the load if the transmitter power is already known.

3- Connect the forward power and reflected power voltage terminals of the BPS to separate metering inputs on your Davicom RTU.

Metering Inputs Configuration Using the Web Interface

Configure the metering inputs for Forward Power and Reflected Power through the RTU’s web interface:

1- Open a web browser and connect to the Davicom RTU’s web interface using its IP address.

2- Navigate to Inputs > Metering Inputs.

3- For each metering input:

• Select the input connected to the Forward Power terminal of the BPS.
• Configure the following parameters:
  • Description: Forward Power
  • Measurement Unit: Watts (or as applicable)
  • Normal Value: Enter the typical forward power value for your setup.
  • Calibration Coefficients: Input the specific coefficients (A, B, C) from the BPS documentation based on the operational frequency:
    • BPS1050 at 170 MHz: A = 8.9053, B = 4.4987, C = 0
    • BPS5095 at 870 MHz: A = 4.5311, B = 3.0904, C = 0
• Repeat this process for the metering input connected to the Reflected Power terminal, adjusting the description accordingly.

BPS Calibration

Accurate calibration ensures the Davicom RTU’s forward power reading matches the actual transmitter output:

1- Use a Reference Meter: Set up an inline power meter between the BPS and the load to act as your reference.

2- Turn On the Transmitter: Power up the transmitter and stabilize its output.

3- Adjust the Calibration Trimmer:

• Locate the forward voltage calibration trimmer on the BPS sensor.
• Using a small insulated screwdriver, gently adjust the trimmer while monitoring the forward power reading on the Davicom RTU.
• Continue adjusting until the forward power reading displayed by the Davicom RTU matches the reference value shown on the inline power meter.

Automatic VSWR Calculation Configuration

Once the metering inputs are calibrated, you can set up automatic VSWR calculation:

1- Navigate to Inputs > Math Functions in the RTU’s web interface.

2- Choose an available math function slot.

3- In the Operator dropdown menu, select the SWR function.

4- In the fields provided for the SWR operator:

• Field A (Reflected Power): Enter the ID for the metering input connected to the reflected power terminal of the BPS.
  For example, if Reflected Power is connected to Metering Input 8, the ID will typically be 1A8.
• Field B (Forward Power): Enter the ID for the metering input connected to the forward power terminal of the BPS.
  For example, if Forward Power is connected to Metering Input 7, the ID will typically be 1A7.

5- Assign a description to the math function, such as “VSWR Calculation.”

6- Save the settings to activate the VSWR calculation.

Displaying VSWR Reading

1- Navigate to the monitoring panel in the web interface.

2- Add the configured math function to a dashboard or display panel for real-time VSWR monitoring.

The post How to Measure VSWR with BPS RF Power Sensors and a Davicom RTU appeared first on Davicom Exchange Support Portal (DEX).

The physical slot into which a board is installed always represents the I/O identifier prefix.

For example, if an Analog Board is installed in slot 1, its ID prefix will be 1. So inputs it would be 1A1 to 1A8.

If the same board would be moved to slot 2, its input ID would change to 2A1 to 2A8. On this last example, if a Digital Board is installed in vacated slot 1, then the Digital I/O would be 1D1 to 1D8. If a relay board is installed in slot 3, then the relays would be identified as 3R1 to 3R5.

A NEURO with 5 Analog Boards would have 40 inputs identified as: 1A1 to 1A8, 2A1 to 2A8, 3A1 to 3A8 … 5A1 to 5A8.

Note that the numbering convention is different when the NEURO is used in MODBUS mode. See this article for details on the register structure.

In the SNMP MIB, the I/O OID’s all follow a continuous numbering scheme similar to the MODBUS convention.

For the next step, please connect a network (Ethernet) cable between the AXON/NEURO and your computer. The AXON/NEURO should have been previously powered-up as explained in this article.
