• Manufacturer Part Number: RCT-A330KQS20R470M
• Description: Ac Termination Network ? Rct-a
• Manufacturer: Viking Tech Corporation

IEEE 1284 ECP/EPP TERMINATION NETWORK — RCT-B
The RCT-B is an IEEE 1284 compliant termination network that provides complete pull-up, series
termination, and EMI filtering for an ECP/EPP parallel port. The RCT-B provides a complete parallel
port termination solution in just two packages, which saves board space and reduced assembly costs
by replacing 54 discrete components.
Advanced, high-speed parallel ports conforming to the IEEE 1284 standard are used to provide
communications between the host computer and external devices such as printers, tape back-up
drives, ZIP drives, parallel port SCSI adapters, external LAN adapters, scanners, and other PC
peripherals. These advanced ports support bi-directional data transfer rates to 2MB/sec and above.
The IEEE1284 standard recommends a combined pull-up, termination and filter network between the
driver/receiver and cable at both ends of the parallel port interface. In addition, government EMC
regulations impose the need to include EMI filtering on the parallel port.
