RE: Eclair ACL Modification of Eclair Motors to accept Arri-Speed Controllers

[Mark <super16acl@aol.com>]

Here is a call to all you electronic-types out there. 

At: <A HREF="www.members.aol.com/HeresTheFile">www.members.aol.com/HeresTheFile</A>

there is a schematic of the CP modified ACL motor that can be downloaded.  Is 
anyone knowledgeable able to spot the 9 places where wires would have to be 
soldered to connect an 11-pin FISHER Socket so that this motor can accept 
Speed Controllers designed for the Arri?  (I'm making the possibly erronious 
assumption that no extra parts are necessary).

11-Pin Fisher Connector for Arri Speed-Controller Compatibility: 

Pin 1. Signal Ground; 
Pin 2. Shutter Pulses (TTL)- output, 1 per frame; 
Pin 5. External Synch Enable- input; 
Pin 6. Tach. Pulses- output, 200 pulses per frame; 
Pin 7. Remote ON/OFF - motor will run if pin connected to +12V (for ACL II 
base only); 
Pin 8. External Synch. (TTL)- input, 3200 pulses per frame; 
Pin 9. 0 volts from camera battery; 
Pin 11. +12 volts from camera battery. 

The above info was obtained from the AZ Spectrum SIte, which lists the 
connections necessary to install an 11-pin Fisher socket to an ACL motor. (AZ 
Spectrum makes Speed Controllers that use the 11-pin Fisher Connector). They 
will also do the modification for $650.

This modification should, in theory, also allow the ACL to use Tobin Speed 
Controllers along with Tobin's Fisher cable.

Thanks. Mark.
