FTDI
Information
This is Four Channel relay board controlled by computer USB port. The usb relay board is with 4 SPDT relays rated up to 10A each. You may control devices 220V / 120V (up to 4) directly with one such relay unit. It is fully powered by the computer USB port. Suitable for home automation applications, hobby projects, industrial automation. The free software DRM and DRMv3 allows to control relays manually, create timers (weekly and calendar) and multivibrators, use date and time for alarms. We developed also command line tool utility for controlling the relays. We provide software examples in Labview, .NET, Java, Borland C++, Python.
Autodiscovery
The autodiscovery will only find 4 relays when this hardware is used. Even when the board contains 8 or more relays. This is due to the fact it is impossible to detect how many relays a board has. The minimum is 4, so that is why only 4 relays will be auto discovered during startup. If your board has more relays, you have to add them manually.
Setup
Auto detect
This relay will be auto detected during startup or added by ‘Scan relays’ in the menu.
In order to use the FTDI use the following settings:
Mandatory
- Hardware
- FTDI devices
- Address
- Enter the relay number from 1 - 4. Optional add the serial of the board separated by a comma.
Ex:1,A702JH8H
