Model 700 Programmer – Operations Manual
MODEL 700 “SINGLE PLUG” INTERFACE SPECIFICATION
The new version of the Model 700 Programmer will have, in addition to the normal
interface jacks on the back panel, a single, 12 pin connector which contains all
necessary interface signals for controlling any synthesizer. When a matching connector
is built into another synthesizer by either the manufacturer as part of the unit, or by
independent owners or service centres it will be possible to completely interface the
programmer with a single patch cord, rather than the many that are now required. The
advantages of this approach are obvious.
The type of connectors to be used is from Viking Industries, Inc., (21001Nordhoff St.,
Chatsworth, CA 91311 (213) 341-4330) specifically their THORCOM line of commercial
circular connectors. These connectors are small and low cost, but by using gold-plated
contacts, the reliability is very good. Viking also makes custom moulded cables to fit
these connectors.
The specific receptacle part number that we will be using in the 700 is a TKR12-1017
that cost about $0.42 in 1000 quantity. The pin contacts that will be used are TP-100AU,
costing about $0.08 each in 10,000 quantities. 12 pins will be installed, with one not
assigned (spare). These pins are used with a crimp tool, but PC board pins are also
available. A custom 6-foot connecting cable will cost about $10.23 in 1000 quantities.
This cable will snap lock on the connector for a positive connection (squeezing the
connector is necessary for removal.)
The actual pin assignment that will be used is as follows:
Pin 1

Note that for some synthesizers, all of the pins will not be used. These pins can be left
out of the connector on the synthesizer as a cost savings, as can pin 12.
