Fiber-Optic Data Link Specifications
These plug-ins can be added to the System 8000 chassis to provide a full duplex data path connecting the M and
C computer terminals at the antenna site and the equipment room. The standard version is for RS-422 serial data
with an option for RS-232. This link provides a data path only; there is no hand shaking, so a modem must be used
at each computer.
