B–5 Host I/O Interfaces
Dataproducts Parallel Interface
This interface allows the printer to operate with controllers designed for
Dataproducts printers. The interface is capable of transferring up to 500,000
characters per second. The maximum cable length from the controller (host
computer) to the printer is 40 feet.
NOTE: Optional adapter cable (p/n 703316–001) and termination resistors
RP1 330
Ω
(p/n 101381–331) and RP2 220
Ω
(p/n 101381–002) are
required.
Dataproducts Interface Connector Pin Assignments
The printer provides a 36–pin D–shell connector on the rear panel for connection
of a parallel interface cable. This 36–pin connector requires a cable adapter to
convert it to a 50–pin AMP connector for Dataproducts compatibility. Contact
the factory for the adapter (p/n 703316–001). Table B–2 lists the pin assignments
of the Dataproducts cable adapter.
