WTE MReX Programming Board
Introduction
The MReX Programming Board is a USB to 3.3V TTL serial board, designed to interface the MReX Module or the MReX PCB to a computer or USB host terminal. The board physical dimensions are 48mm X 24mm X 5mm (L x W x H).
Board Details
Top view
The following 3D images show the top side of the board. On this side of the
board you can find:
- Micro USB connection header
- RX and TX status LEDs
- V-USB jumper blob solder jumper header
- Through-hole pin header connections
V-USB
The board is capable of providing 5V to the MReX module (VCC). This can be
achieved by making a solder blob on the V-USB pads.
Bottom Side
The bottom side of the MReX Programming Board has the connection labels.
Programming Requirements
In order to program the MReX board you need:
- A USB cable with micro USB connector for the programming board to PC connection
- A PC with a USB port
- A serial terminal application/software. We recommend the use of the WTE serial terminal application, which can be downloaded at no cost from our WTE website (https://www.wte.co.nz/tools.html)
- An MReX 460 module or MReX PCB board is to be configured.
Usage Example
The following example shows the MReX PCB, being connected and powered by the MReX Programming Board.
Note:
If the MReX PCB board is NOT being powered via the USB, please ignore Step
Step 1
Remove batteries/power from the MReX 460 since the MReX is powered from the
USB connection
Step 2
Plug the micro USB connector cable into the programmer board. Connect the
other end of the USB cable to your PC, and ensure V-USB is blob soldered
.
The following steps are assuming you are using the free WTE Serial Terminal PC application.
Step 3
Plug the programmer board into the header as shown in the photos. It’s easy to
get it the wrong way around so replicate the photo
Note: At this moment the MReX Module will the powered and depending on the MReX configuration it should flash its green status led.
Step 4
Run the serial terminal application. If you are using the WTE Serial Terminal,
first press Settings and select the USB serial port and 9600 baud, press OK.
Then press Connect
Step 5
If the MReX is asleep (for ultra-low power consumption) it needs to be woken
up before using the WTE Serial Terminal. To wake the MReX an input must be
triggered. The MReX flashes the green led once a second
Step 6
A simple test to ensure the Serial Terminal is communicating with the MReX is
to press the SEND button to the right of the first line of the command table
(ie the *CONFIG\r command). All the current settings of the MReX should stream
up in green text on the right panel:
Step 7
You are now ready to start configuring the MReX, please refer to the MReX User
Manual. Please download the MReX User Manual from the WTE website
(https://www.wte.co.nz/mrex.html).
