4-port, synchronous serial communications, HDLC, and SDLC protocol support

DNx-SL-504

Features

The DNx-SL-504 is no longer available for purchase. Post-sales support for this product will continue. UEI has designed the DNx-SL-504-802 as a functional replacement.

4-Port Synchronous Serial Communications

4 independently configurable ports

Each port software-configurable as RS-232 or RS-485/422/423

Max speed of 230 kbaud for RS-232 and 4 Mbaud for RS-485/422

HDLC, SDLC protocol support

350 V port-to-port isolation; 15kV ESD

The DNx-SL-504 has 4-port serial communications interfaces for Cube and RACKtangle I/O chassis. Each port may be independently configurable as RS-232, RS-485, RS-422/423 as well as set for synchronous communications. Each port is fully isolated from the other three ports and from the Cube or RACKtangle chassis. The board is an ideal interface to a wide variety of serial based data acquisition and control interfaces as well as general purpose serial I/O.

The DNx-SL-504 supports most popular synchronous serial communication protocols, including HDLC and SDLC. The RS-485/422 implementation provides transmit and receive, data and clock interface while the RS-232 configuration also supports standard CTS and RTS signals. The maximum transfer rate in RS-485/422 and RS-232 modes are 4 Mbaud and 230 kbaud respectively.

Note: This product is no longer available. There are two chipsets we cannot source. Post-sales support for this product will continue. UEI has designed the DNx-SL-504-802 as a functional replacement for these products. It uses the same Z16C32 chip type as a protocol controller thus software and functionality remain identical.
