I have been getting a bit frustrated waiting around for my Tronisoft Papy kit and I would like to play a little with the Merlin/Orion head using a wired connection. 
On one end, we have a Mac (that can run Windows XP under Parallels). Available ports: Ethernet and USB. I have a Keyspan USB to Serial converter. I have a null-modem cable, if needed.
On the other end, we have the Orion/Merlin with what appears to be a RJ11 phone jack.
How do we best make the twain meet? BTW - I already have Papywizard running in Windows XP under Parallels.

You need an RS232-TLL convertor and some way of powering it, 2x220 ohm resistors, and an RJ-11 cable - in other words the equivalent of the Tronisoft kit without the BTLink Bluetooth-RS232 adapter - and a straight through 9-way serial cable.
Someting like this - but you'd need to figure out how to power it - a battery perhaps?

This one is port powered if your USB-serial convertor can provide the power?:

And you could mod. this and it works direct from USB:

What TTL line level should we be using. I see cables like this running either 5V or 3.3V ?
Cheers,
Jeremy

The Merlin/Orion uses 5V TTL level. But it should be possible to use 3.3V TTL interface. Be sure their inputs can be wired to 5V levels (using a limitation resistor), and also that 3.3V output is enough for Merlin inputs (does anybody has make a test?).

this cable should work

Hi all,
3.3V modules don't work with the Merlin/Orion who use 5V, except if they are equiped with a "Dual Voltage Level Shifter" (like the SN74LVC8T245DGVR from Texas Instrument) this allows for universal low-voltage bidirectional translation between any of the 1.8-V,2.5-V, 3.3-V, and 5.5-V voltage nodes!
Some BT modules are allready equiped with a level shifter ( e.g. Sparkfun BlueSmirf, A7eng EB301 ...)
Actually, I finish my small study about finding "alternative to Tronisoft" (ongoing practical experiments) and I will communicate soon with recommandations (max 5 days more please!) 
Be patient ! 
Concerning the USB converter from FTDI, don't buy the 3.3V model but the 5V model and it will work !
(not the "FTDI TTL-232R 3.3V" but the "FTDI TTL-232R", both 2 currently available also from FTDI http://apple.clickandbuild.com/cnb/shop … :+TTL-232R or other current sources)

The cable as purchased is only 1.8m - by how much could you extend the cable?
I guess you still need the 2x220ohm resistors?
Offline
Hi All,
Andrew is right ...
Only 1,8 m lenght yes! But USB cale extension are common ....
Yes, of course, the 2 resistors 220 Ohms are mandatory !

wired connection with a standard USB cable and this converter and the two resistors

Paul,
It seems the wired option you listed is a cheap one, particularly for US based users. If I have a PC (w/Windows XP), Merlin, shutter release cable, USB cable, two resistors (2x 220 Ohm), Papywizard, and the converter, is there anything else I would need to have a functional PW/Merlin?
If so, has anyone assembled a tutorial how to assemble this wired option? I would be fine with tethered functionality.
Offline
just solder the two resistors to a 4 wire phone cord RJ12
and connect RX TX Ground

Thanks Paul! My soldering iron has not arrived yet, so I may have more questions once I get my hands dirty.
Cheers, LeRoy

Hallo Paul, Hi Paul,
following your suggestion i ordered this article and am trying to get it working now...
Two things you could maybe help me with:
- where do i connect the 5V+? -> CTS# - ? / GND - Ground / RXD - Data (1x 220 Ohm) / UCC - ? / RTS# - ? / TXD - Data (1x 220 Ohm)
(i am not sure and tried it on UCC but i do get an USB-undercurrent error on my computer when connecting it)
- any hint how or what i have to choose in the system setting on Mac OS X?
I installed the new connection (with theis archive: FTDIUSBSerialDriver_v2_2_10.dmg) and activated it in the system preferences - but there are so many options there... (modem etc.).
Thanks - Danke - Peter

no need to wire up 5V as they are supplied via the usb connector
Mac: sorry, I am using only unreal stuff ...

Ok - i will try that... when i get the new adapter. The one i tried earlier is dead.
But which cable is which on the RJ11 connector going into the Merlin? There are 4 cables and i saw two different schemes how to connect them in this forum - as i have destroyed already one adapter i am a bit "unsure" now...
----------------
| yellow -> ?
| green -> ?
| brown -> ?
| white -> ?
----------------
The connectors looking up - the nose facing down - the cable going off to the right.
THANK YOU!!!

Look at:
http://www.autopano.net/forum/p27797-20 … -41#p27797
Yellow = GND
Green = NC
Brown = +12V
White = DATA
If you are using a USB cable, then you don't need to wire the +12V from the Merlin; just use GND, and DATA (through resistors, to RD and WR).

This was the image i soldered the cable after... and which killed my adapter and shut off my computer. The computer is ok but the adapter is dead. Maybe i did a mistake - i will doublecheck again when i get a new adapter.
I had tried another scheme before but then the computer told me that there was not enough power to establish the USB connection. So i thought this was wrong.
Thanks a lot for now (as i have nothing to experiment with right now :-(

As long as you don't wire the +12V from the Merlin, or the +5V from the USB adapter, you shouldn't burn anything. If you have a doubt, use a voltmeter to see where is the +12V...

Hi - i am back with a new adapter.
I soldered it now as advised and my Mac lists the adapter under USB devices. This is from the log:
/var/log/system.log.0.bz2:Apr 17 21:48:44 360pixel kernel[0]: FTDIUSBSerialDriver: 0 4036001 start - ok
How can i determine now the serial-port i have to tell Papywizard under Preferences? I tried some (like 0,1,4,5) but Papywizard does connect to the hardware. Also the adapter does not show any blinking LEDs.
More hints how to get that connection going under OS X 10.5.6?
Thank you!!!

Hi Peter,
I know just nothing about MAC, but you can have a look hereafter:

Hi Claudevh,
looks interesting - but i have no folder called "/dev", just an alias. Where should it normally point to? I will have a deeper look into it...
Thanks - i will keep you informed.
Peter

Where does the alias lead? What does the following command return:
$ ls /dev/*
Offline
Hi, we are getting nearer (well, i am with your help):
i looked into /dev as Frederic described (with the adapter connected - otherwise it is is not shown!!!) and here is the relevant part:
/dev/ptys0 /dev/tty.usbserial-A6007ZIp /dev/ttyw5
I then entered this line ("/dev/tty.usbserial-A6007ZIp") in Papywizard under serial port but there is another error: (Papywizard log):

Papywizard then went into simulation mode.
At least Papywizard seems to see the adapter now but the communication does not work yet.:-)

[SOLVED]
Sorry guys - i had not connected the power cord to the Merlin... its rotating!!! :-))))
I just made it move in the two axis and it follows. Big grin!!!
Thank you so far - i will write this "connecting to Mac story" together in a shorter form later for easier reading.

Hi Peter,
Very happy for you !
I am still looking for "correct" replacement solution to the Parallax EB501 ser...
I wil come back with that later.
