Astronics / EADS / Racal 6065P-4 4-Channel Serial Interface Card with Programmable Data Rate

The Astronics / EADS / Racal 6065P-4 is a 4-channel serial interface card for VXIbus systems, delivering flexible multi-protocol serial communication with independent channel configuration. Each of the four channels configures independently as RS-232, RS-422, RS-423, or RS-485, supporting programmable data rates from 1.7 Baud to 125k Baud with seamless operation up to 38400 Baud without dead time. The card provides 512kB of allocatable input/output buffer memory and operates under SCPI control for standardized instrument programming. ## Technical Specifications • Channels: 4 independent serial channels • Interface Protocols: RS-232, RS-422, RS-423, RS-485 (selectable per channel) • Data Rate: 1.7 Baud to 125k Baud (programmable); supports continuous operation to 38400 Baud • Buffer Memory: 512kB allocatable to input and output buffers • Protocol Configuration: Software-programmable word length, parity checking, handshaking, and baud rate per channel • Non-volatile Storage: Configuration memory retained across power cycles • Form Factor: C-size VXIbus compatible ## Key Features • Independent per-channel protocol and baud rate selection eliminates cross-channel constraints • Software-controlled loopback at the line driver/receiver level for self-test verification • Simultaneous full-duplex transmit and receive on all four channels • SCPI compliance enables integration into automated test environments • Programmable key parameters stored in non-volatile memory ## Typical Applications VXIbus-based serial data acquisition, multi-instrument control, protocol conversion testing, and embedded system communication validation where diverse serial standards must operate in parallel. ## Compatibility & Integration Designed for C-size VXIbus message-based systems. SCPI programming language support provides direct integration with standard instrument control frameworks and automated test software.
