The Digi One SP device server easily allows any device with a serial port to be connected to the Ethernet. The compact design of the Digi One SP delivers cost-effective performance and capability in one of the smallest form factors available.
Part of Digi’s broad device server offering, the Digi One SP delivers standard serial-to-Ethernet connectivity and is ideal for serial tunneling applications or where TCP Socket, UDP Socket, or UDP
Multicast functionality is needed. Serial tunneling allows two previously non-networked and isolated devices to easily communicate information and operate with existing installed software applications on an Ethernet network, instead of a long serial cable. The Digi One SP works with software applications using TCP/UDP Sockets allowing a serial device to interoperate with the software applications without the need to install a driver.
The Digi One SP is easy to install locally or remotely through a variety of IP addressing methods (DHCP, RARP, ARP-Ping) along with an application (included on the installation CD that accompanies the product) that will automatically detect all Digi One SP devices on your network. Also included is a quick-start guide that supports making
the network configuration of the product easy and hassle-free.
Features:
TCP/UDP socket services
UDP Multicast
Telnet and Reverse Telnet
HTTP
DHCP/RARP/ARP-Ping for IP Address
assignment
10/100BASE-T Ethernet support
DB-9M serial connector
EIA-232/422/485 switch selectable
Baud rates up to 230Kbps
Full modem and hardware flow control
LED status for link and power
Connectivity
10/100Mbps Ethernet port : 1
Serial port : 1
