Turns out the SSD was corrupted. Re-imaging it sorted it out. Thank you to btreinders.

Appreciate the responses. I guess I'll put in a ticket and see. My ISY994's have been rock solid so I was a little surprised at the fragility.

Thank you. Read though the WIKI several times. The boot sequence just goes immediatly to left LED solid. No beep. Been through the troubleshooting section. Installed a new ISY launcher instance but still cannot find or manually add the Polisy. I can SSH to it and login in so it's somewhat alive and the network connection is good. The WIKI says not to update it using SSH and there is little info on any commands. Since I'm stuck, can it be updated using SSH?

I have been using ISY994 for years, decided I needed something else to fiddle with, and picked up a used Polisy inexpensively. Seemed to work fine. Went to Admin console, Help, and saw an update was available. Started the update. The left LED was solid and the middle started flashing rapidly. Next day it was the same so cycled the power and now no comms. All three lights come on briefly and the leftmost stays lit. It is assigned an IP address and responds to a ping but that's it. ISY launcher can't see it and I can’t add it (Not Found). Chrome can't see it either (This site can’t be reached). Pressing and holding the multifunction button seems to do nothing. After reading the Wiki apparently that was the wrong place to start the update. Any ideas or is just stuffed? I’d be grateful for any suggestions. Dante

Joy! Thank you to everyone that responded to my request for help. To control the PJ an initialization string is sent and shown in the first post and then commands can be sent. This is exactly how it works using the terminal. Using the ISY I would send the initialization in binary mode and I would see the correct Resource Response "ESC/VP.net". Any subsequent command would return the "TCP client read response failed". But again, it worked properly for the initial string. Turns out if the command string is appended to the initialization string it works and the Resource Response is correct. So the ISY does in fact read the response. Here is a screen shot asking for the PJ power status. The command is PWR? CF LF and the response is PWR=04: which is the standby state. It's a good day.

Thank you for the encouragement. So I turned it around and Hercules is now a TCP Server and I have the ISY sending to my PC. The only thing obvious is that Wireshark labels the command from the ISY as Telnet rather than TCP. These are screen captures from sending the same three commands from the PC to the PJ and from the ISY to my PC. The ISY is much more verbose. I picked one of those command packets as an example ASPECT 30. Problem is I don't know what I'm looking for. Terminal to PJ and below that ISY to Terminal

Now I am confused. If I look at my network with Wireshark I see all sorts of stuff that doesn't involve my PC. The Tivo going somewhere, the Roku, etc. I know the terminal is working properly so how do I see what the ISY is sending out to compare it?

I believe I have found the problem. Using WireShark (which is a very cool utility) I can see that the ISY is not sending anything to the desired TCP address. In the attached WireShark file the ISY is 192.168.1.94, my laptop is 245 and the projector is 38. When I ask the ISY to "Test" the TCP string shown in the above post at 5:39 there is nothing going from 192.168.1.94 to 192.168.38. Lots of chatter between the ISY and my laptop but nothing to the projector. At the end I sent the string through the Hercules utility and you see the expected conversation. So what am I doing wrong? Why is there nothing being sent by the ISY? ISY_test.pcapng

I am not particularly network savvy so please bear with me here. I have WireShark and the Hercules utility on the same PC. Everything is Ethernet through switches. Using Wireshark and the filter tcp port 3629 and host 192.168.1.38 (the projector) I can see the commands sent to/from the Hercules utility and the projector. A command is sent to the PJ, there is a response back, and then another message from Hercules to the PJ If I tell the ISY to test I don't see anything captured. Do I need a different filter to see the ISY communications or am I doing something else wrong?

Thank you. Unfortunately this did not work when trying to send the ASCII command so I've gone back to trying to work out sending the decimal strings in binary mode. I am perplexed why I can send hex codes with the Hercules utility and everything works fine. Converting the initialization string from hex to decimal and using the ISY will work and return the response from the projector. Any subsequent attempt to send a valid command string using the same protocol results in the "TCP client read response failed" message. What is difference between the terminal utility and the ISY Network Resources that I am missing? Initialization command: Command to get the current power status is PWR? <CR> <LF>:

Thank you. The immediate question is how to format the unprintable characters (like a CR/LF, ASCII 13) for string in the "Body" field?

So I am still stuck. Using a terminal program (Hercules) I can send commands in HEX or ASCII to the projector and everything works fine. Using the ISY I can send the initialization string using decimal characters in binary mode. I even get the correct response from the projector. Try to send any command, again using decimal characters/binary mode and I get the TCP error. I've double checked my HEX to decimal conversion but I still cannot get this to go. The IP is correct, the port is correct and the command example here is ASPECT 30 41 53 50 45 43 54 20 33 30 0d hex 65;83;80;69;67;84;32;51;48;13 decimal Any ideas at all? I've been obsessed with sorting this out. I'd like to try ASCII using the C Escaped mode but I don't know the format for unprintable ASCII characters. In particular NUL and CR/LF. ISY.docx

Duh, found the answer to my own question as far as hex in the previous post. Convert to binary. Can I use ASCII? Are there any ISY programming examples for parsing responses and acting on them?

I am trying to send command strings to an Epson PJ using TCP via Network Resources. The strings can be ASCII or hex and I am struggling to figure out the formatting to send/receive either. For instance ASCII is "ESC/VP.net<DLE><ETX><NUL><NUL><NUL><NUL>" or HEX "45 53 43 2F 56 50 2E 6E 65 74 10 03 00 00 00 00" If accepted a colon is the response. I can communicate fine with Hercules. What Network Resources "Mode" do I use and how do I specify the ASCII special characters? Or should I use HEX and how do I format that? I've looked at the WIKI and the links for examples seem dead. Any help would be greatly appreciated or please point me to some reference material.

Perfect. Thank you very much.
