The Complete ProXR Command Set:

The ProXR Standard for Data Collection and Control
By now, you have seen ProXR all over our web site.  Just about every controller we currently make is a ProXR controller.  You will find ProXR in relays, inputs, outputs, potentiometers, analog to digital conversion, and much more.  Put simply, ProXR is a standardized set of commands.  When you choose a ProXR controller, you can upgrade that controller without having to re-write your software.  One of the greatest benefits to ProXR is that you can develop your software to work with (for instance) an RS-232 device.  Later on, you may find you don't want to use RS-232 any more.  Maybe you want to talk to the device wirelessly, or maybe use an Ethernet, Wi-Fi, USB, or Bluetooth interface.  No Problem.  You don't have to re-write your program.  You can simply use the communication technology that most benefits your application WITHOUT having to redevelop your software.

ProXR is rooted in simplicity just as much as it is standardization.  Most people who visit our web site are programmers who need to integrate a custom hardware application with a minimal learning curve.  If you are a programmer, then you are ready to dive right in and start communicating with our devices.  But we also work with several customers who have NO PROGRAMMING EXPERIENCE.  And we take pride in making sure these people are brought up to speed with a simple set of tutorials.  So whether you are a programmer or an electrician, we can help get you started.  We move at a pace you can easily follow, so you don't have to worry too much about steep learning curves.  We put a lot of effort into making our devices easy to use and standardized, while supporting all of today's popular communication technologies at a pace anyone can understand.

Before we dive into the command set, there are three reading prerequisites:

1)  Our articles will introduce you to various technologies, and you should read the article that pertains to your favored communication technology first.  Click here to see our articles.

2)  Review our tutorials, they will give you everything you need for first time users to configure a programming language to speak to our devices.

3)  Our ProXR Manual gives you lots of background details on our robust and growing ProXR command set.  Use it as a reference, even if you are an experienced programmer.

The purpose of this article is to give you a convenient location to review a summary of ProXR commands.  This list will only grow as our products evolve.  This list is divided into 4 simple categories: Input, Parameters, Description, and Output.

Reading the Table
Command These are the bytes that you send to the controller.  These bytes are shown in decimal format, and can be converted to HEX if you prefer.  We use the comma character to separate our bytes, but you should NOT send the comma character to the device.  Also, you do NOT need to send a enter or return to complete the command.  The controller knows when the command is complete.
Parameters Some commands need parameters, such as hours, minutes, and seconds.  Other parameters include a Bank value, which indicates which group of relays you will be speaking to.
Command Description While there is no substitute for reading the ProXR manual, these descriptions give you a basic guideline of what to expect from the command.
Response ProXR controllers will respond to most commands that you send.  Under normal operation (when the controller is in runtime mode) the controller will respond with an 85 for most commands.  If the controller happens to be in configuration mode (a jumper setting on the controller), the controller will respond with 86.  Some commands, such as Analog to Digital Conversion, report 8-bit values from 0-255.  In some cases, 2 or more bytes are sent back to the user.  These will be noted in the Response column. 

Example:  The following command activates the first relay in Bank 1

254, 108, 1    Activate First Relay in Bank 1, Controller Responds with 85 when the jumper setting on the controller is in RUN mode.  If the controller is in CONFIG or SETUP mode, the controller will respond with 86.

If your programming language supports HEX instead of decimal values, you can send the same thing by converting the command to its equivalent HEX values:

Send: FE6C01 Hex, the controller will respond with 55 Hex.
 
Please Refer to ProXR Manual For Complete Description of these Commands

Section 4: SCAN Series Contact Closure Input Detection

The following command works with all SCAN series controllers and all UXP Series controllers equipped with a USCS Series Contact Closure Input Expansion.
254, 175 Bank (0-255) Read a Bank of Contact Closure Inputs
This command is used to read a group of 8 contact closure inputs.  This command returns a value from 0-255 indicating the on/off status of 8 contact closure inputs.  Using the math function "AND", it is possible to read individual inputs as needed.  Here is a quick example:

Send 254, 175, 0 to read the first bank of contact closure inputs. 
The controller will return a value from 0-255 indicating the on/off status of each of the 8 inputs on the first bank.  For instance, the controller may return the value 170.  You can apply the AND function to the value of 170 to see the on/off status of each bit.  Start by assuming each bit is OFF.

VALUE=170
If (VALUE AND 1) = 1 then BIT 0 is ON
If (VALUE AND 2) = 2 then BIT 1 is ON
If (VALUE AND 4) = 4 then BIT 2 is ON
If (VALUE AND 8) = 8 then BIT 3 is ON
If (VALUE AND 16) = 16 then BIT 4 is ON
If (VALUE AND 32) = 32 then BIT 5 is ON
If (VALUE AND 64) = 64 then BIT 6 is ON
If (VALUE AND 128) = 128 then BIT 7 is ON

This command returns 18 bytes of data in Order:
Header Byte, Channels 0-15, Checksum Byte at End of Packet.

Checksum Value Always Equals the Sum of All Bytes Sent, Including the Header.  The Checksum Value is Always 8-Bits.  You Should Extract the Lower 8 Bits from the Checksum to Return a Matched Value.  Use This Formula:

CheckSumTest = Sum of All Bytes Sent from Controller
CheckSum = Last Byte Sent from Controller
(CheckSumTest AND 255) MUST Equal CheckSum

The AND Function Used in the Above Formula is a Mathematical Function that Returns (in this case) the Lower 8 Bits of the CheckSumTest.  AND is supported by Most Programming Languages.

254,202 none Read All 16 Channels at a Time, 8-Bit A/D Device Bank 2 of 2.
This command returns 18 bytes of data in Order:
Header Byte, Channels 0-15, Checksum Byte at End of Packet.

Checksum Value Always Equals the Sum of All Bytes Sent, Including the Header.  The Checksum Value is Always 8-Bits.  You Should Extract the Lower 8 Bits from the Checksum to Return a Matched Value.  Use This Formula:

CheckSumTest = Sum of All Bytes Sent from Controller
CheckSum = Last Byte Sent from Controller
(CheckSumTest AND 255) MUST Equal CheckSum

The AND Function Used in the Above Formula is a Mathematical Function that Returns (in this case) the Lower 8 Bits of the CheckSumTest.  AND is supported by Most Programming Languages.
