TOSR04-D - 4 Channel USB/Wireless Timer Relay Module Xbee Control Kit

This is an Xbee Relay remote control kit. The kit package includes:

• 1 x TOSR04-D 4 Channel USB/Wireless Relay Module
• 2 x XBee S1 Wireless modules
• 1 x XBee USB adapter
• 1 x Mini USB cable

Description: This USB/Wireless relay module allows computer controlled switching of external devices by using the USB port of your computer.

It has a wireless extension port, that can work with XBee or Bluetooth Bee or Wifly modules, which means now you can control your device by Zigbee or Bluetooth or WiFi.

The TOSR04-D module can be 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.

It also supports the delay timer function. You can set each relay output delay from 0 second - 24 hours.

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 DC 5V.

First Step - Install the Driver
The TOSR04-D module uses FT232RL USB to UART chip. Before using the TOSR04-D you will need to download the FT232RL Driver.

Connect the TOSR04-D and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

The TOSR04-D will now appear as a com port.

Commands
The TOSR04-D operates with an easy to use command set as described in the table below.

TOSR04-D Baud rate : 9600 

Test program and example source code
To get the TOSR04-D up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
