API for Windows to interact with board via USB (updated)


We require an API for Windows to be developed in ASP.NET, to interact with a board that connects to a computer via USB. The communication with the board is to be accomplished through AT commands.

Some of required functionalities

2 types of commands,

- Functional - related to the operation of inputs and outputs

- Informative - Help List of the commands and the firmware version.


The API must load a config file on the same directory as the parameters:

* username

* password

Command Format

AT + f n e <CR> <LF>

All commands must first terminate by carriage return <CR> (0x0D) (/ r), optionally new line <LF> (0x0A) (/ n) can be included next


This board has 4 fixed inputs (1 @ 4) and an AUXILIARY (A) that is shared with an output according to the position of a JUMPER. If nothing is connected to that entry, read 1


This board have 5 power outputs (1 @ 4) and an AUXILIARY (which is shared with an input according to the position of a JUMPER) with 4A power management.

IMPORTANT NOTE: The developer select will NOT have access to the actual board. It is the developer job to write the code, and deliver it to us for testing and approval.
