Datasheet

Layer 2 functions
Packets sent in response to LCOS service requests (e.g. for Telnet, SSH, SNTP, SMTP, HTTP(S), SNMP, etc.) via Ethernet can be routed directly to the
requesting station (default) or to a target determined by ARP lookup
ARP lookup
Automatic discovery of network topology in layer 2 networks (Link Layer Discover Protocol).LLDP
COM port server
COM-port server for DIN and USB interfaces. For multiple serial devices connected to it, the server also manages its own virtual COM ports via
Telnet (RFC 2217) for remote maintenance (works with popular virtual COM-port drivers compliant with RFC 2217). Switchable newline conversion
and alternative binary mode. TCP keepalive according to RFC 1122 with configurable keepalive interval, retransmission timeout and retries
COM port forwarding
USB print server
Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possiblePrint server (USB 2.0)

WAN: ADSL2+
4 individual 10/100/1000 Mbps Ethernet ports; up to 3 ports can be switched as additional WAN ports with load balancing. Ethernet ports can be
electrically disabled within LCOS configuration. The ports support energy saving according to IEEE 802.3az
Ethernet ports
Each Ethernet port can be freely configured (LAN, DMZ, WAN, monitor port, off). LAN ports can be operated as a switch or separately. Additionally,
external DSL modems or termination routers can be operated as a WAN port with load balancing and policy-based routing. DMZ ports can be
operated with their own IP address range without NAT
Port configuration
USB 2.0 hi-speed host port for connecting USB printers (USB print server), serial devices (COM port server), USB data storage (FAT file system);
bi-directional data exchange is possible
USB 2.0 host port
ISDN BRI port (S0 bus)ISDN
Serial configuration interface / COM port (8 pin Mini-DIN): 9,600 - 115,000 baud, suitable for optional connection of analog/GPRS modems. Supports
internal COM port server and allows for transparent asynchronous transmission of serial data via TCP
