The device will serve as the link between the Panduza platform and the Voxpower to command the inhibiters. The platform will use a serial communication with the board and the board will deliver 5V to the desired channel.
The board used must be an Arduino UNO R3
The connection between the PC and the Arduino must be via an USB 2.0 A to B.
The connection between the Arduino and the Vox Power must be via simple cables linked to the connectors.
The connectors for the Vox Power must be :
| Manufacturer | Housing | Terminal |
|---|---|---|
| Molex | 511101251 | 503948051 |
The inhibiter pinout must be :
| Arduino | D2 | D3 | D4 | D5 | A0 | A1 | A2 | A3 | GND |
|---|---|---|---|---|---|---|---|---|---|
| Vox | INH1 | INH2 | INH3 | INH4 | INH5 | INH6 | INH7 | INH8 | COM |
The USB configuration must be done with a serial link and a baud rate of 115200.
The protocol to specify the action (inhibit or enable or state) and the channel N must be :
"I" N
"E" N
"S" NWhen receiving a "S" the Arduino must return the state "H" or "L" of the specified pin. When changing the state, the Arduino must return the state "H" or "L" of the specified pin.
