Connects to Third Party Devices
RS-232 devices are perhaps versatile and most popular choices because of their ability to adapt to any other communication protocol and devices. For instance, using 3rd party devices, RS-232 relay controllers can be controlled from GSM modems, Ethernet to Serial Adapters, WiFi to Serial Adapters, USB to Serial Adapters, Bluetooth to Serial Adapters, and Wireless Mesh Network to Serial Adapters. RS-232 will continue to adapt to all emerging technologies, as the foundation for all communication technologies has provisions for RS-232 communications. With the DB-9 or direct wire capabilities this controller can connect to third party devices including Crestron almost any way possible.
Integrates with Crestron
This relay can integrate with Crestron, in fact we have many Crestron customers using our devices. The most important thing you need to know is how to format the data out the serial port of the Crestron device. Our devices work with Hex/Decimal byte values. Crestron systems usually work with Hex values, our devices start with a header byte of 254, followed by a command (ProXR controllers need 254, 108, 1 to activate the first relay). So you need to convert all of these values to Hex for the Crestron system and send the bytes out the port. For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.Mounts as a COM Port
This ProXR Lite series controller connects to the RS-232 port of your computer and requires a 12VDC Power Supply. This ProXR series controller connects to the serial port of your computer and will mount as a COM port on your PC. Once powered up, the controller waits for a command. A command consists of a few bytes of data in numerical format 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.ZRS Modules
This board is equipped with a ZRS Module. The ZRS RS-232 Serial Interface module adds a serial port to the NCD line of products. The ZRS Module
is offered with 3 different RS-232 connection options depending on the wiring option that best suits your application. The ZRS module is powered from the serial port of your computer. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.
Three ZRS Modules Available
There are three RS-232 connection options available for this controller.

| ZRS-A Wire It Up |
ZRS-B Plug It In |
ZRS-AB Both! |
Choose Your Connector
Choose the connection that fits your needs. The ZRS-A connection is recommended for applications where hard wiring directly to the board is needed. ZRS-B has the full 9-Pin DB-9 connector on the board. The ZRS-AB Has the DB-9 connector but is is located off the board for applications where the board may be place inside an enclosure an the RS-232 connector needs to reach to the side of the enclosure. You can choose one of these connection options at checkout.Induction Capacitors
Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of Serial devices, it is not as severe as using a USB port a capacitor is still recommended. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.
USB Induction Solution
If USB is required, an RS-232 communications module will allow RS-232 communications between your PC and controller with no complications. A USB to RS-232 adapter (available at checkout) can be used in combination with the RS-232 controller. The RS-232 communications format with a capacitor effectively blocks induction to safe levels for a USB to RS-232 adapter to function without errors.ProXR Lite Relay
In this tab we'll take a look at the board design itself. The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design. Fully tested before they leave the production facility each ProXR Lite controller is ready to stand up to rigorous demands from heat, cold or vibration. The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions. Take it from us, these controllers will hold up!
Not Expandable
Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.Full ProXR Enhanced Firmware Installed

Easy Software Development
Most of our customers write their own program for controlling these relays. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language. These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the board. Not a programmer, check out N-Button! Software that allows you to configure buttons to control relays and read the status of those relays without programming using point-and-click action.

Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. Read and control from 8 sensors per board from 0 to 5 volts (0 being a dry contact)! A/D inputs are ideal for reading the on/off status of switches, connect a switch between input and ground and software may then be used to monitor the contact closure status of the switch. AD inputs can also be used for reading variable resistance signals, the board will then will return a value between 0-255. Click the grey Data Sheets tab above and look for the AD8 Quick Start Guide to see the full AD command set.SPST Relay Installed
This board has SPST relays installed. SPST Single Pole Single Throw Relays simply connect two wires together. 
The Common (COM) is the moving part of the relay that comes in contact with the Normally Open (NO) when the coil to the relay is energized. Wiring is done directly to the Relay terminals using a common 1/4" quick disconnect terminal. To the right is a picture of the connector that will connect to the relay.
