Serial Device Server
Applications
Wireless Serial Tunneling
Two native serial devices can communicate over a wireless Ethernet network without any intermediate host PC and software programming. Both Ad-hoc and infrastructure mode for
wireless operation are selectable so that EKI-1300 series wireless serial device servers can connect to an AP (Access Point) or two EKI-1300 series wireless serial device servers can
directly communicate without AP.
Multi-Access
Traditional --- Single Access
Most serial devices are connected directly to the PC serial port via cable. The OS, such as Windows XP, provides the COM ports that the application can access, and control the serial
device through the serial cable. This means that the serial device can be connected to one host and only one application on this host can handle input, output and control operation.
Advanced --- Multi-Access
Advantech ADAM-4570 series, EKI-1500 series, and EKI-1300 series allow a maximum of 5 hosts connected to one serial port simultaneously and handle the commands from each
host and reply to all hosts or the host that query depending on the easily configuration. Advantech serial device servers have two kinds of operating modes for multi-access. First
is broadcast mode; serial device servers handle a command from one application and reply the data from the serial port to all applications connected to this serial port. The other is
polling mode; serial device servers handle the command from one application and reply to this application only. Query from other applications must be queued and wait for current
process completion.
Dual Ethernet Redundancy
Advantech EKI-1500 series provide dual Ethernet connections for building reliable and redundant networks. Through the serial device servers, users can establish two physical
networks in the same domain, one for the primary connection, and the other is a backup host that can connect to the serial device servers directly when the primary connection fails.
Furthermore, the two Ethernet ports can be set to two different networking domains to support different network applications.
