RS-232 Serial Interface Module

ZRS Modules

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.

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.

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.

RoHS Compliant

This module 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.
