Ideal for extending multiple devices with asynchronous RS232 or RS422 interface, or units with synchronous V.35 interface, across fiber
8 independent full-duplex asynchronous ports with ordering option for RS232 or RS422 interface. Maximum port speed on each of these ports can be 230,400 bps. Each port has 1500 VAC Isolation protection on it. Another ordering time option is available to split each RS232/RS422 port into 2 full-duplex ports, thereby doubling overall port availability.
Up to 4 out of the 8 ports may be ordered with synchronous ports with V.35/X.21 interface in lieu of as many asynchronous ports. Synchronous V.35/X.21 ports can operate at speeds from 64 kbps to 256 kbps, and may be used for interconnecting Routers (through WAN ports), Multiplexers, etc.
Option for simultaneous 10/100 Mbps Ethernet along with the serial ports, via a built-in 4-port Switch. This allows simultaneous LAN extension over fiber at a throughput of up to 12.5 Mbps (nominal).
Driving range: up to 20 km (using single mode fiber)
Option for backup fiber port with hot standby functionality
Multiple methods of managing the unit:
• Through DIP switches and RS 232 compatible console port
• Through a separate 10/100 Base-T Ethernet Port supporting SNMP and TELNET (optional)
Loop back and test pattern facilities for quick fault isolation on both fiber and DTE interfaces
Front panel indicators for displaying unit status.
Ordering time option for 230 VAC or 48 VDC power supply.
Applications include extending booking counters, ticket vending machines and information display systems from one platform to another, Router WAN port connectivity, etc.
