emu71 - Hello World to ILVideo - HowTo ? - mstram - 12-10-2014 06:18 PM
I have emu71 (Windows Version), IlVideo and ILctrl all running.
I can send a msg from ILctrl to IlVideo from the 'Data' dropdown.
Now how do I send from the emu71 to Ilvideo ?
Can the emu71 dos version talk to the IlPer / IlVideo utilities ?
I have virtual com ports software running, if that helps.

Get the HP-IL address of the video display.
For example if the address is 3, on Emu71, type "DISPLAY is :3" (wihtout quotes), which makes the device at HP-IL address 3 act as the system display.
Note: At work, so I can't try it, but it should work.
If not, get the Device ID string using V$=DEVID$(:V), [again use the address, not actually "V"] then type "DISPLAY IS V$" wihtout the quotes
Lastly (or even firstly), you can try "DISPLAY IS DISPLAY", but I don't know if the virtual ILVideo has the proper HP-IL device attributes; knowing Christoph, I imagine it is correct.
Good luck, and please report results.

With ILPer you can execute DISPLAY IS PRINTER. But, ILCtrl and Emu71 are both Controllers, and you can only have one controller in the loop unless one is disabled with CONTROL OFF.

"DISPLAY IS DISPLAY" is just fine. The display is detected over his AID.

Thanks guys I'm getting output on the video now.
Is it possible to connect both the IlVideo and the Ilper to the emu71 ?
I assigned unique ports to each device (60000, 60001 for the Ilvideo, and 60010,60011 for the ILper), and added the Hpilrom.bin file to both ports 1, 2
How do I access the devices?
It seems like there is a device #1 on both ports ?
Is there a port qualifier ?
I'm trying to use the HP Software Developers Handbook, which only has a brief mention of device addressing.

You have to configure the virtual HP-IL interface on Emu71 (on the HPIL configure screen). Basically, each device on the virtual loop connects daisy-chain fashion, with each device pointing to the next device's address for the OUT and that next device pointing back at prior device for the IN. Keep in mind it's a loop so it has to end the same place it begins.
Something like this:
Emu71 IN 60000, OUT 60001
ILPer IN 60001, OUT 60002
ILVideo IN 60002, OUT 60000
HTH
Thanks Christoph for confirming.

Ok, I get it. I have it working so I can issue DISPLAY is DISPLAY or DISPLAY IS PRINTER.
Thanks !
