Re: Best HDMI Matrix Switcher for 4X4: Still AVPro Edge?
I have a ton of Atlona post-covid and have not seen this issue in the past year and a half. They were the available product when supply chains were nightmares, and I ended up sticking with them for a while.
This will change soon as I look more into Q-Sys and AVoIP style systems for the next rev. |

PRO3 IP/USB weird behaviour
Hello.
in a museum we have a PRO3 and a PC with an XPanel. The PC also is used as a remote access for troubleshooting. The service call mentionned that the XPanel was showing "disconnected, trying to reconnect" When I log into the PC remotely, all the settings of the XPanel are OK, toolbox can discover the PRO3 and the other Crestron touchpanels but I can NOT access the processor via system info and a connection via putty is immediately rejected. I can connect into the touchpanels without issue. I can ping the PRO3 from the PC. I changed the IP address of the PC to another and same problem. We then had a employee from the museum connect the PRO3 to the PC via USB I can access with toolbox via USB, everything seems normal, no IPs blocked, everything in the iptable is connected and running but the XPanel. Surprise, I can now connect via IP too ! Until the customer disconnects the USB cable... Is there any magic that I don't get? I can connect by IP only when the USB cable is connected. |

Re: RFID in classroom AV system
If they have to scan a card anyway, have you thought about a card swipe ? ?I have one that you swipe and it outputs serial directly. ?No external RFID readers or arduinos needed. ?Embed code in the card for different people and recall different presets /access levels. ?

MC3 Stuck in EBOOT,OS,
I've had this thing sitting in my office for years, only used it a couple of times.
Decided I'd stick it on Ebay and get rid of it once and for all. Gave it a clean and decided to upgrade the FW from 1.012.0017 to latest 1.502.0051 for whomever buys it. As per FW instructions I ftp'd the file over and issued a PUF?mc3_1.502.0051.puf command. EBOOT upgraded from v1.25.0 to v1.26.0 successfully. OS stated it was updating from v1.012.0017 to v1.502.4324.33148 Now the MC3 appears to be stuck in bootloader as I'm getting... EBOOT,OS, |? ? ?|? ? |? ? ?| N/A | N/A | ...repeating constantly Is this now a brick? |

Re: RFID in classroom AV system
I second the recommendation for HID Multiclass.? Enterprise quality unit and will read most anything. As you noted, needs an Arduino to convert signaling to RS232.? For anyone interested I can recommend a good board and share code to do this, you just flash the code to a brand new board once over USB, the code includes wiring directions.? I really like the brand ¡°Ruggeduino¡± for quality, and their extreme flexibility on supply voltage, and have never had one fail. ? I haven¡¯t yet dug into OSDP but I might one day.? Any time I have had polling or timing objectives to meet, I have dedicated a second Arduino chosen for its _lack_ of network support, just to that single task, and linked them via i2c or serial because you can control everything and ensure there are no competing tasks on chip.? Same idea can solve Crestron driver timing limitations.? A cooperating Arduino between Crestron and a timing sensitive device works magic, you can nail timing down to the ¦Ìs with the Arduino and relieve the Crestron driver of meeting timing burdens.? I believe that any device that multitasks or talks to a network is going to have hard limitations on meeting a strict timing spec, and yet, 8 bit arduinos are cheap, dependable, keep great timing, they boot in under 1 second, and the typical code for a single time-sensitive task often fits in a screenshot.? I treat the ESP32 and ESP8266 Arduino device as a specialist in talking to networks and I configure them to self-reboot upon any sustained degradation of network performance, and also try to avoid giving ESP¡¯s timing sensitive work.? If the other Arduino keeps the protocol state, the pair can fully recover from one¡¯s intentional rebooting.? This ¡°two-Arduino combo¡± makes for some very robust solutions that just do their job without fuss, and self-recover from temporary network or power issues really well.? Also on the other hand, for simplicity¡¯s sake, I have done installs where I skipped Arduino entirely, implemented RFID to Crestron where an access control system was already established, using established system¡¯s hardware to add one more ¡°door¡±.? But instead of powering a door strike, wired the door system¡¯s relay contact to a hard Crestron input. That solves all of the ¡°user enrollment¡± logistics ¡ª client uses their existing solution (which already supports enterprise features like scheduling, logging, and access rights) and treats the interface as though it were another ¡°door¡± that can be administered just like any other.? Crestron won¡¯t know who the user is, but depending on the use case, that may be no problem.? Mike On Thu, Apr 18, 2024 at 12:48?PM Lincoln King-Cliby via <lincoln=[email protected]> wrote:

Re: smpl+ help with making a code to reverse string
tested ...on english its working?
thank you now i need to figure out why?on utf16 its dont ,that before the reverse metod the utf worked but reversed . thanks for the advise ,it work nice!? the problem is that i have tried to give a quick solution for construct import from vtp file to support right to left strings , but it not only the reverse characters? Because the utf16 character are bulild from a code that represt the font , its just reverse the abc and the font won't show because the code for the font changes if anyone has advice or wait for the suport of RTL etire string for construct . |

Re: smpl+ help with making a code to reverse string
You could try something like this:
DIGITAL_INPUT Test_Reverse; BUFFER_INPUT Key_Input$[1024]; String_Output Out$; Push Test_Reverse { String working$[1024], building$[1024]; If(Len(Key_Input$)) { working$ = Key_Input$; ClearBuffer(Key_Input$); While(Len(working$)) { building$ = Remove(Left(working$,1), working$) + building$; } Out$ = building$; } Else Out$ = "No string to reverse"; } |

Re: RFID in classroom AV system
¿ªÔÆÌåÓýI¡¯m using HID Prox (specifically MultiClass SE readers and generally iClass SE credentials) for access control at home ¨C ESP8266s running Arduino code handle the Weigand-to-Crestron conversion because OSDP (over RS485) is problematic for me (primarily because I¡¯m cheap, but the OSDP I¡¯ve played with has tighter polling requirements than I¡¯m able to achieve without making things grumpy). ? If you¡¯re pretty much anywhere in the US that already uses a card access control system there¡¯s a very good chance it¡¯s using a HID prox technology already ¨C either 125 KHz or 13.5 MHz ¨C and generally (except for certain Corporate 1000 custom encryption keys on the 13.5 MHz iClass side of things and some ancient Motorola Indlala-based systems) a MultiClass reader is be able to read any access token in common circulation (Outside the US there are some other formats like EM4200 that MultiClass readers can read ¨C but also some that they can¡¯t) ? The bigger challenge if you¡¯re looking to reuse an existing credential is managing expiration/loss/reissuance expectations so if this is at scale you may be better off looking at integrating with the access control system (either via API or doing slightly ugly things like treating the room like an elevator where every user unlocks different ¡°floors¡± (capabilities/presets)) so that (a) you don¡¯t have to put yourself in the actual card transaction and (b) when their card is reissued (because it was lost or expired) you don¡¯t have to worry about updating the token ID on your side of things ¨C it just works (or stops working, if the card was disabled) ? If you¡¯re living in a HID 125 KHz world, HID has a 54xx series reader that outputs RS232 over one way serial. It¡¯s pretty limited (no control over the beeper or LED, just spits out the card ID that it read with a line feed IIRC. (But 125KHz is also slowly dying off for institutional use because it in its most common form it is insecure as it allows for a fairly small cardholder population) ? If you¡¯re not worried about matching an existing credential ¨C there are a plethora of EM4200 readers that output RS232 but I don¡¯t have any that I would recommend and there are the same small universe issues that make it less appealing for a new install. ?

smpl+ help with making a code to reverse string
hello,
i need some advice how to do in smpl + a code to reverse a full string of my keybourd . what i have done so far is : /*
? DIGITAL, ANALOG and SERIAL INPUTS and OUTPUTS
? (Uncomment and declare inputs and outputs as needed)
*/
// DIGITAL_INPUT?
// ANALOG_INPUT?
STRING_INPUT Key_input$[1024];
DIGITAL_INPUT Clear,Back;
?
/*

? (Uncomment and declare global variables as needed)
? Note:? Be sure to initialize all declared STRING variables as needed
? ? ? ? ?For example, in Function Main: myString = "";
*/
// INTEGER
// LONG_INTEGER
// SIGNED_INTEGER
// SIGNED_LONG_INTEGER
STRING Internal_buffer[1024];
//STRING originalString[255] = "Hello, world!";
STRING reversedString[1024],DESTINATION_STRING[1024];
?INTEGER i,stringLength;
String_Function ReverseString(string SOURCE_STRING)
{
? ??
? ? ? ? stringLength = LEN(SOURCE_STRING);
? ? // Start from the end of the string and copy characters to reversedString in reverse order
? ? FOR(i = 0 to i < stringLength step 1)
? ? {
? ? ? ? reversedString[i] = SOURCE_STRING[stringLength - i - 1];
? ? }
? ? reversedString[stringLength] = ""; // Null-terminate the reversed string
?
? ? ?RETURN (reversedString);
}
CHANGE Key_input$
{
? ?// reversedString = ReverseString(Internal_buffer);
?
Internal_buffer = Key_input$ + Internal_buffer;
reversedString = ReverseString(Internal_buffer);
?
Key_shifted$ = reversedString;
}
?
?
PUSH Clear
{
Internal_buffer = "";
}
?
PUSH Back
{
if(len(Key_input$) < 0)
{
Key_shifted$ = right(Key_input$, len(Key_input$) - 1);
}
}
?
?
?
?
? /*
PUSH Back
{
if(len(TextIn$) < 0)
{
Text$ = left(TextIn$, len(TextIn$) - 1);
}
}
/*
? Main()
? Uncomment and place one-time startup code here
? (This code will get called when the system starts up)

/*

}
*/
i get erors that the function is missing ; here:? FOR(i = 0 to i < stringLength step 1)
? ? {
line missing ; ===? ? ? ? reversedString[i] = SOURCE_STRING[stringLength - i - 1]; //something i am doing with the array is porbaly not good
? ? }
?line missing ; ===? ???? reversedString[stringLength] = ""; // Null-terminate the reversed string
can someone help ,or give direction what is wrong? ? |

Re: RFID in classroom AV system
Yeah you can get them at DangerousThings.com It¡¯s sort of like a piercing and sort of like a pet chip for dogs/cats but injected into your hand. ?readable by commercially available RFID readers Hurts like hell for 5 seconds to get put in As an integrator you can do neat wizardly stuff with it.? That¡¯s sort of how I got into messing with the Arduinos, they will convert the signal from most any RFID reader to any format you want (relay closure, rs232/485, you name it), so, every size and shape of reader is an option.? Embed mini readers in furniture to unlock the drawers, put standard RFID readers on doors, or (Crestron example) bury a reader in the wall under a touchscreen that skips you past a passcode or into a hidden menu.?

Re: RFID in classroom AV system
I can help with this.? First, do you know what kind of RFID card or token is going to be used?? (Is it an existing badge that users already carry, or one where you will be passing cards or tokens out -- such as "one per preset" and... you can select the card technology)?? (if you can select the technology, you might be aware that cards come in multiple formats, including keyfobs, stickers, coin-shaped discs, or other objects, if that helps your use case)
Second, what kind of reader will be used?? Do you get to select it, or do you have to work with something that exists?? If you select it, what's the desired physical format (e.g. a wall mount similar to what you see on doors? a device that sits on a desktop?? something hidden behind another surface?? how compact would you like it?) As for how it's going to talk to Crestron, you can assume the RFID can be made to send a string to a Crestron serial port (simplest), or a TCP/UDP port (less simple since there will be a network conversion step involved).? Will you be able to work with that on the Crestron side? For what it's worth, I have an RFID chip embedded in my hand, and love making awesome integrations with it, including with Crestron.? There's lots of options! |
