Ethernet to Serial/Modem Adapter Board

LSDB-8300 Series

Introduction:

The Radicom LSDB-8300 series offers an embedded solution for a Ethernet to Serial or Ethernet to Modem interface. The LSDB-8300M Module provides the reserved through hole (DIP) pin headers for the Serial Port TTL I/O and Ethernet pins that allow the Jacks to be placed in preferred locations. The TTL I/O can then be converted to RS232 signaling and connected to a DB9 connector to provide a fully compliant V24/V28, RS232 interface. Interface. The LSDB-8300NE is a standalone product embedded with a RJ45 Ethernet jack to provide the Ethernet interface and DB-9 for RS232 direct plug-in. The LSDB-8302T is a standalone product provides easy connection to any standard Ethernet port and Tiny Modem dial-up network. The LSDB-8303A is an All-in-one solution to provide POE, SIA alarm Modem, WiFi, RS232/485.
LSDB-8301HM is a small form factor of Ethernet to SIA alarm and LASDB-8301HC is not only provide analog SIA modem as well as emulate central office with line current provided.

This product allows serial data communication with any 10/100 Based-T Ethernet LAN. The LSDB-8300EVK along with LSDB-8300MB development board also provides RJ45 and DB9 connectors for LSDB-8300M module testing and developing purpose.

The onboard Ethernet functions are designed to meet the widely adopted IEEE Std. 802.3™ with automation and buffering. The integrated serial port includes standard serial terminal features such as flow control, character length and a DTE speed of 921.6Kbps. The LSDB-8300 series includes Flash memory allowing for updating firmware with the latest
enhancements and for custom applications. Users can make changes to web server applications such as configuration of local hardware using Telnet or FTP.
