Introducing ProXR:
Not Just a
Latching Relay Board Anymore!
It is one thing to build a latching relay board with a powerful command set and lots of features. We have been doing that for years. It becomes an entirely different breed of controller when the relay controller is capable of watching over your computer when things don't always go as planned.
New for 2006, the ProXR Series Latching Relay boards have the most powerful relay control command set we have ever produced, plus the addition of 16 user-programmable timers, capable of performing watchdog, keep-alive, and Server Reboot timing operations to help make sure your computer is never down.
Other timing features allow you to (for example) turn on a light for 8 hours. Just send the command and forget it, the controller will automatically turn the light off when the elapsed time has expired. There are 16 timers, so you can turn on 16 different lights for different periods of time.
Out of the box, the ProXR series controllers are ready to control 256 relays. You may not have 256 relays just yet, but if your application grows, then the controller is ready to grow with you. The ProXR series controllers are built from the ground up to be expanded. When you need more relays, the XR Expansion port will allow you to add another bank of relays (any kind you need), with programming changes taking minutes instead of hours. No complicated protocols, just simplicity, built into the controller from the very beginning.

| Above: The ProXR Series controllers are capable of controlling up to 256 relays. Weather you need power switching or DPDT signal switching, the ProXR Series are built from the ground up with Expansion in mind. Simply Chain the XR Expansion Modules, one after another, to meet your computer controlled switching requirements.

ProXR series controllers connect to the RS-232 port of your computer. If you don't have an RS-232 port, a USB to Serial adapter works perfectly. Once powered up, the relay controller waits for a command. You know the processor is working when you see the heartbeat LED flash. A command consists of a few bytes of data. Usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.
You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours. You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired.
We have also added a Server Reboot Pulse timing feature that is particularly useful for rebooting up to 16 servers. It works like this. Connect the RESET wires on your motherboard to the Normally Open and Common connections on any of the 256 possible relays.
Next, send a command to the relay controller to activate up to 16 Server Reboot timers. You can specify hours, minutes, and seconds as part of the command. Your program should constantly reset the clock built into the relay controller. If the computer ever crashes, it cannot reset the clock built into the relay controller. When the timer expires on the relay controller, the relay will send a reboot pulse to any of the 256 relays, rebooting your computer.
The features list of the ProXR series controllers is extensive. Our ProXR Software helps get you acquainted with the powerful command set. Should you have any questions, please
