USB/Wireless Relay  module Description:

This USB/Wireless Relay Module allows computer control switching of external devices by using the USB port of your computer!
Meanwhile, It  has a wireless extension port, can work with XBEE or Bluetooth Bee or Wifly Module, which mean now you can control your device by zigbee or Bluetooth or WiFi !The TOSR0x module can powered by USB bus or DC power and provides two volt free contact relay outputs with a current rating of up to 10 Amp each.

Relay power rating
If the relay is used at a voltage or current exceeding this specification, the life of the contacts may be significantly shortened.

A full datasheet for the relays used on the TOSR0x is here: G5LA datasheet

If you use DC Power ,the Input voltage should be DC5V.

First Step - Install the Driver
The TOSR0x module uses FT232RL USB to UART chip . Before using the TOSR0x you will need to download the FT232RL Driver.
Connect the TOSR0x and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.
The TOSR0x will now appear as a com port.

Commands
The TOSR0x operates with an easy to use command set as described in the table below.

TOSR0x Baud rate : 9600 

Test program and example source code
To get the TOSR0x up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
