CAMAC crate interface with ES computer via the ES-7922 local group controller

The interface for data exchange between CAMAC crate and ES computer using ES-7920 local terminal system communication protocol and connected to ES-7922 local group controller via coaxial cable up to 1200 m in length has been developed. The interface is described for OS ES as ES 7927 display terminal. Data can be transferred at maximum speed up to 20 kbyte/s(using a modified ES-7922 controller-up to 40 kbyte/s). There were realized measures to exclude data stream collisions between CAMAC crate controller and ES-7922 controller having different timing. 5 refs.; 1 fig.; 2 tabs
