PRELIMINARY DISCUSSION
The
VCR control is implemented by associating System 9760 GPIs to VCRs. When a GPI is used for VCR control, its first seven auxiliary relays are used to control the seven most common VCR control functions. The seven auxiliary relay numbers and their associated VCR functions are listed below.

Two key setup procedures are required in order to accomplish VCR control from the Sys- tem 9760. The Frame Address Table in Figure 10 can be used as an aid to implement both procedures.
