Control Network Media Tank with telnet

RolfW

Hi all

Has anyone tried to control a NMT (Popcorn Hour) with AMX?
It can be controlled with telnet from a pc
http://www.networkedmediatank.com/showthread.php?tid=30168&page=1

I open the socket with netcat <ip> <port> and control the device with commands like "echo x". this works perfectly
With wireshark, I see TCP packets with the following Data: echo x$0A
But if i open a Port with AMX like this IP_CLIENT_OPEN(10,'192.168.200.138',30000,IP_TCP)
and send the string (over Control Device on 0:10:1) "'echo x',$0A" theres no action at all.

Am I doing something wrong?
what is the general way to send telnet commands with AMX?

Hope you guys have helpful tipps!
Cheers

Isn't Telnet port 23?
So your command should be IP_CLIENT_OPEN(10,'192.168.200.138',23,IP_TCP)
What errors is NetLinx spitting back at you?

RolfW

usually it is, but as you can see in wireshark, the commands are sent with port 30000.
In the other thread i posted, there's port 23 not open.

i get no errors from netlinx in diagnostics... or where should the error happen?

other suggestions?

You can't use "control a device" to control something through Ethernet. At least, I have never been able to get it to work...

Try this to open the socket

nIPClientResult = IP_CLIENT_OPEN(dvPopcorn.Port,hostIpAddress,hostPort, 1)

Example:
dvPopcorn = 0:5:0
hostIpAddress = '192.168.1.1'
hostPort = 30000

Also, don't terminate your command with $0A, use $0D in stead

SEND_STRING dvPopcorn, "'echo x',$0D";

Good luck, what commands can you execute on the Popcorn by the way?

RolfW

oh wow, you're right!
if I "hardcode" it, it works perfect!
beautyful!!!

there are lot's of commands. they tried almost every command on the link i posted.

thank you!
nice weekend guys
cheers

RolfW

by the way, it works with $0A AND $0D

Ahh..
I missed the crucial part! That will teach me to skim!

PS Can you please keep us informed of your progress? I have a Popcorn Hour NMT as well.

RolfW

sure!
one update: don't send the "echo".
you only need to send the command (e.g. "x" for on/off)

but it's sad that you get no feedback over ip... would be great if someone has an idea to get feedback!

Best Regards

That would be a first try with usual snapi-codes...

SWITCH(nBTN1)
{
CASE 1: //Play
{
SEND_STRING dvNMT, "'y',$0D"
}
CASE 2: //Stop
{
SEND_STRING dvNMT, "'s',$0D"
}
CASE 3: //Pause
{
SEND_STRING dvNMT, "'p',$0D"
}
CASE 4: //Next
{
SEND_STRING dvNMT, "'n',$0D"
}
CASE 5: //Previous
{
SEND_STRING dvNMT, "'E',$0D"
}
CASE 6: //Fast Forward
{
SEND_STRING dvNMT, "'f',$0D"
}
CASE 7: //Fast Rewind
{
SEND_STRING dvNMT, "'w',$0D"
}
CASE 21: //Enter
{
SEND_STRING dvNMT, "'Enter',$0D"
}
CASE 22: //Home
{
SEND_STRING dvNMT, "'O',$0D"
}
CASE 45: //Up
{
SEND_STRING dvNMT, "'U',$0D"
}
CASE 46: //Down
{
SEND_STRING dvNMT, "'D',$0D"
}
CASE 47: //Left
{
SEND_STRING dvNMT, "'L',$0D"
}
CASE 48: //Right
{
SEND_STRING dvNMT, "'R',$0D"
}
CASE 27: //On/Off
{
SEND_STRING dvNMT, "'x',$0D"
}
CASE 44: //Menu
{
SEND_STRING dvNMT, "'m',$0D"
}
CASE 100: //Sub Title
{
SEND_STRING dvNMT, "'b',$0D"
}
CASE 116: //Zoom
{
SEND_STRING dvNMT, "'z',$0D"
}
CASE 118: //Audio
{
SEND_STRING dvNMT, "'a',$0D"
}
CASE 120: //Eject
{
SEND_STRING dvNMT, "'j',$0D"
}
}

Better than nothing I guess, feedback would be nice though
