Hello [joelkarr53],

I've recently worked on the same Epson 982W model and other Epson projectors. I was unable to get the HTTP requests from Companion to work using the EpsonPJ module, so I decided to use the PJLINK protocol, which is natively supported by Epson and works very well. Here’s what I found:

1. Analyzing Companion's Behavior with EpsonPJ:

• ARP and HTTP Requests: We observed that Companion, via the EpsonPJ module, first sends an ARP request to obtain the projector's MAC address. This MAC address is then used in the subsequent HTTP request as a KEY parameter. For example, the Power Off command might include a parameter like KEY=6C in the HTTP request.
• Timestamp in HTTP Request: The HTTP request also contains a _ parameter that appears to be a timestamp, likely used to prevent caching of requests.
• Note: These HTTP requests are very similar to those sent when using the projector’s web interface to turn it on or off.
• Outcome: Despite this analysis, we haven’t yet succeeded in getting these HTTP commands to properly control the projector from Companion.

2. PJLINK Solutions:

Prerequisites:

• Ensure that PJLINK is activated on the Epson 982W. You can do this through the projector’s network settings, and make sure it's configured without a password or with a blank password.

• Activate the "Network Standby" option so that the network interface remains active even when the projector is turned off.

• Make sure you’re using port 4352 for PJLINK communications, as this is the standard port.

  Solutions:

• Option 1: Use Companion with the TCP Generic Module

  • If you prefer to stick with Companion, you can configure the TCP Generic module to send PJLink commands. By using the CR - \r (1970's RS232 terminal) line-ending setting, the commands (%1POWR 1 for power on, %1POWR 0 for power off) were accepted and worked correctly.
  • This setup allows you to send PJLink commands directly through Companion.

  • 

• Option 2: Simplify with Command Sender in Stream Deck

  • For a more straightforward approach, you can use Command Sender with Stream Deck. This method worked well for sending PJLink commands. You can configure buttons to power the projector on/off using PJLink commands (%1POWR 1\r for power on, %1POWR 0\r for power off).
  • This is a convenient solution if you already use a Stream Deck in your setup.

  • 

• Option 3: Test Commands with Hercules

  • For testing purposes, Hercules is an excellent tool. We used Hercules to successfully send PJLink commands. After configuring the connection (receiving a PJLINK 0 response), we were able to send POWR 1 and POWR 0 commands by simply adding <cr> (carriage return) at the end of each command (%1POWR 1<cr> for power on and %1POWR 0<cr> for power off).
  • This solution was confirmed by discussions on forums and worked for us, though it’s noted that it may not always work depending on specific conditions.

We hope this information will be helpful for controlling your Epson 982W. Feel free to reach out if you need further assistance.

Have you tried the native PJLink module in Companion?

[Florent-ARENE]

Hello,

Yes, controlling the projector via the PJLink module in Companion works very well. We have successfully tested this method on an Epson 982W model, and it reliably handles power on, power off, and other PJLink commands.

We hope this information will be helpful to joelkarr53 and assist him in resolving his issue.

Thank you for your support.
