RS-232 Interface Modules
NCD RS-232 modules make it easy to integrate the worlds most prolific communication standard. Easily interface to desktop PCs and laptops for easy control via standard serial commands. Most NCD devices typically default to 115.2K Baud.
The RS-232 Interface
Connects to Third Party DevicesRS-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.
ZRS ModuleThis 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 AvailableThere are three RS-232 connection options available for this board.

Plug It In
Integrates with CrestronThis board 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 PortThis 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.
Induction CapacitorsPerhaps 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 SolutionIf 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 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 Expandable Board
This Board includes the XR Expansion Port for adding additional relays to the board. The XR Expansion Boards can be added to control up to 256 relays on this board!
The ProXR Relay Board
ProXR RelayWe've looked at the interface now let's take a look at the board design and programming. The ProXR series controllers are manufactured by hand for a highly accurate and reliable design. Equipped with the XR Expansion Port additional relays can be easily added. Fully tested before they leave the production facility each ProXR 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!
UXP ExpansionUXP is a standardized data port, specifically for the purpose of speaking to various expansion modules. This controller is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. You will find the UXP port on models with UXP in the part number.
UXP Expansion ModulesUXP Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. A master device is an NCD controller with a UXP expansion port and a microprocessor of some kind. Most master UXP devices have on-board relays. If you need to add A/D, Contact Closure Inputs or Digital Potentiometers just plug in the appropriate expansion module. You cannot daisy chain different types of modules to the same controller however. In other words if you plug in a potentiometer you will not be able to plug a contact closure or A/D module also. For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number. All UXP Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for.
- Summary of UXP Modules
- Compatible with UXP Series Controllers ONLY
- Not a stand-alone controller - MUST be used with a UXP Series Controller
- Add Contact Closure Inputs
- up to 256 Inputs
- Add Analog to Digital Inputs
- up to 48 Inputs
- Add Digital Potentiometer Outputs
- up to 256 Outputs
XR Expansion PortMost UXP controllers (Master Devices) have an XR expansion port and therefore can accommodate XR Expansion Boards. Typically the XR Expansion port is used to add relays to the main controller (Master Device). Like the UXP Expansion boards the XR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. When you run out of relays, just plug in an XR expansion board that is equipped with the kind of relays you need. You can add up to 256 relays including the relays that are on the main controller (Master Device). All XR Expansion modules are compatible with each other so if you want to add different types of relays you can. For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.
Using XR and UXP TogetherIf you select a board that is equipped with both XR and UXP port you can use both ports simultaneously. This allows you to add and control more relays through the XR port plus add A/D, Contact Closures or Potentiometers to the same board through the UXP port. This can all be controlled through the same virtual COM port on your computer. These Expansion Boards can be purchase with the controller or purchased at a later time when you have a need to expand. To use both ports together you will need to select a controller that has UXP and PROXR in the part number to have bothports available on the controller (Master Device).

SPST Relay InstalledThis device 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 left is a picture of the connector that will connect to the relay.
2-Million CyclesProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.
Essential Power RequirementsApplying 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.

This Board is RoHS CompliantThis board is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.
16 User-Programmable TimersThe ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer. The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications. Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.
Easy Software DevelopmentMost of our customers write their own program for controlling these devices. 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 device.
