Serial and IR Automation Specifications and Programming Guide for iScan VP20, VP30, VP50 and VP50 PRO Revised - December 2007.
Document Contents 0 Preface ......................................................................................................................... 3 0.1 Information Warranty Statement ................................................................
0 Preface Thank you for purchasing a DVDO iScan VP xx Series video processor. We believe the iScan will become a favorite device in your m ultimedia presentation system due to picture quality, ease of use, and the level of control the iScan gives you or your customer over the processed signal.
0.2 Document Scope and Limitations This document will cover the necessary inform ation required to construct and transmit a serial (RS-232 ) or Infrared (IR) control signal to a DVDO iScan VP xx model video processor.
0.3.2 Product Introduction This section is a brief introduction with pict ures of each of the models of the iScan VP xx series – it is only intended as a brief “spo tters guide” to iScan units. Please refer to your product’s user’s manual or our website for more in-depth pr oduct information at www.
0.3.4 VP30 (MM603) iScan VP30 Front iScan VP30 Back This model is our high-end entry-level pr oduct with the full four HDMI comp lement, the RGBHV/Component 3 input a nd Analog video output – with available options like an SD-SDI input and the ABT102 Deinterlacing add-on card for excepti onal reproduction of interlaced SD content.
0.3.6 VP50 PRO (MM606) iScan VP50 PRO Front iScan VP50 PRO Back The iScan VP50 PRO is the first Video Processor to achieve the THX certif ication f or Video Processors, setting the benchmark for vi deo processing. This device is also the first HDMI 1.
0.4 How does automation work? The iScan line of DVDO brand video processo rs are designed to enable control and flexibility over various input and output signal configurations – as we ll as our proprietary algorithms to improve several aspects of vide o quality and enable new capabilities that legacy devices by themselves are not able to achieve.
0.4.3 What is Binary? The digital world is all ones and zeros. By placing ones and zeros in a standardized pattern we can encode data th at can be exchanged between multiple devices.
As an example, using “65” again – the HEX eq uivalent is “41h”. So what’s the “h” at the end? There are two commonly accepted ways to identify HEX notatio n in a sentence (or “string”).
0.5 A brief dialog about remote controlling a VPxx series video processor Please be honest with yourself and ensu re that you have understood the previous sections.
0.6 A dialog about input video memories Due to the number of inputs and different types of input formats and ever further numerous types of source devices, we at Anchor Bay added input memories, which allow the user/system-integrator to configure very specific “effects” for a specific input form at on a specific input connection.

1 RS-232 Control 1.1 The RS-232 Physical Connection RS-232 connections come in several styl es which are accepted in the consumer electronics industry. The most common is th e 9-pin D-Subminiature connector found on the back of most computers, and is the one that we use on the iScan VP xx products.
1.1.1 The Anchor Bay RS-232 Protocol In this portion of the document, we will dis cus the three types of control communications that occur between th e iScan and the controlling device.
Also, each of the above “characters” has a related HEX notation number to go with it: “Attention” = Start Text or STX = 0x 02 in HEX notation >>pause<< = Null or NUL = 0x 00 in HEX.
Before we start listing Command ID bytes, lets look at the “ this long ” portion of our sentence. For this, count the two command ID bytes (c ount the bytes, don’t add the values!), add the coun.
Let’s look at the sentence agai n, replacing what we know now: “0x 02 0x 33 0x 30 0x 30 0x 35 0x 41 0x 31 0x 00 0x 31 0x 00 [ checksum – optional] 0x 03 ” If you recall, unless your applica ti.
The checksum. This is the last part ot her than the Command ID Table and Value Table you might need to create a comma nd string. Again, unless your custom er/job requirements demand/specify it – YOU.
1.2.1 Example RS-232 Command Packets This section contains the most comm only requested automation command-type strings (no checksums are provided): Power On 0x 02 0x 33 0x 30 0x 35 0x 41 0x 31 0x 00 .

1.3 Query Commands Query commands allow an external device to determine the setting of a given control. Building on the information presente d in th e previous section on constructing Command Packets, we will discuss the method for build ing a Query Packet.
1.4 Responses Responses (aka “feedback”) is arguabl y what really make RS-232 a powerful interface. As opposed to infrared control, the RS-232 port allows for bi-direction al communication, so that the controlling devi ce can get information from the controlled unit to make decisions based on the actual stat e of the unit.
Error “1” – Invalid checksum. This e rror m eans either the checksum you sent was wrong or the transmission was bad due to interference (double check your checksum calculation or your serial link). Error “2” – Invalid Incoming Packet ID (i.
The query response is the most involved re sponse packet you will ge t in reply. This packet can have any data in the “value” bytes (although it will still be ASCII characters in HEX notation). Note that commands like “ Model Name” will reply with text, while commands which are controlled by numbers will reply with n umbers.
2 IR Control We have provided a reprint of Barry G or do n ’s pape r on IR interfacing in Appendix B at the end of this document. If you feel the information provided in the next few sections is a bit confusing, please take a moment to read that document.
2.2 The Anchor Bay IR Protocol (Discrete Control) As stated before, the discrete controls may be longer than the NEC protocol will allow. The NEC protocol only allows fo r one byte of “c ontrol/value” data to be transfer red from the rem ote control to t he controlled device.
If you recall from the RS-232 section, th e comman d ID for the power control is “A ” and “1”, but if you look at th e Pronto HEX format, the command ID can only be o ne byte. This is why we mad e the Command IDs out of “HEX compatible” na ming – so that the same data when represented as a byte will look very familiar.
This writer finds this to be the best step to explai n the “bit burst” count in the Pronto HEX format. The bit burst is every “bit” fro m th e after last “00 00” in the header to the last “bit” in the co mmand defenition. The bits being referred to are in bold and larger above.

A Burst Pair Sequence usually looks as follows: Lead in Burst Pair Data Burst Pairs Lead Out Burst Pair The Lead In Burst pair can be thought of as the hello or wake up burst. It tells the receiver to start listening (or rather looking) ve ry closely as what is com ing.
IR Codes The world of IR remotes has become a commodity world. IR remotes (simple ones, not the Pronto) are rela tively inexpensive. I bought 5, credit card sized, universal remotes for $10. They are three times as thick as a credit card but the sam e height and width.
Let us break it up to decipher it. Preamble 0000 0067 000 0015 Word 1 0 so it is a learned IR code Word 2 103 decimal which when plugged into the formula already given yields an IR Ca rrier frequency of about 40kHz. Word 3 0000 is the length of the On e Time Burst.
Continuing on to the device code we have: Word 21,22 0018 0018 (24,24 decimal) Burst Pair 8, bit 1 = " 0" Word 23,24 0030 0018 (48,24 decimal) Burst Pair 9, bit 2 = " 1" Word 25,26.
NEC IR Code Format Parameter Carrier Freque ncy Unit of Burst Time Lead In Burst "1" Burst Pattern "0" Burst Pattern Lead Out Decimal Value 40kHz 22 cycles o f the carrier 341 171 .
If you work out all of the detailed analys is in a manner similar to that shown for the Sony you should determine that the carrier frequency is indeed 40kHz, there are 34 total burst pairs in the o n e burst s equence use d, and the burst sequence is repeatable.
Appendix C. Help and Support Thanks for taking the time to read this docum ent. W e have tried to cover in easy-to- understand terms, every facet of autom ation the iScan supports – while attempting at answer every question we’ve ever been asked by customers and installers.
An important point after buying a device DVDO VP20 (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought DVDO VP20 yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data DVDO VP20 - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, DVDO VP20 you will learn all the available features of the product, as well as information on its operation. The information that you get DVDO VP20 will certainly help you make a decision on the purchase.
If you already are a holder of DVDO VP20, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime DVDO VP20.
However, one of the most important roles played by the user manual is to help in solving problems with DVDO VP20. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device DVDO VP20 along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
