remote serial devices and equipments over LAN or WAN. The EKI-152X series
comes with a COM port redirector (Virtual COM driver) that transmits all serial signals
intact. This means that your existing COM-based software can be preserved, without
modifying to fulfill the needs. The Virtual COM mode allows user to continue using
RS-232/422/485 serial communications software that was written for pure serial com-
munication applications.
The EKI-152X series comes with COM port redirector (virtual COM driver) that work
with Window 2000/XP/Vista(X86) systems. The driver establishes a transparent con-
nection between host and serial device by mapping the IP of the EKI-152X
seriesserial device server serial port to a local COM port on the host computer.
The EKI-152X series provides Multi-access function through Ethernet connection
path. Allow the maximum of 5 connections to open one serial port simultaneously. In
this mode, all connection has to use the same serial setting. If one serial setting of
these connections is different from others, the data communication may operate
incorrectly.
Host Idle Timeout
The "Host Idle Timeout" setting monitors the connection between the host and the
device. If the "Host Idle Timeout" setting time is reached, the device server will
release the resources allocated to the port mapping. This prevents a stalled host from
affecting the connective device.
The EKI-152X series provides Multi-access function through Ethernet connection
path. Allow the maximum of 5 connections to open one serial port simultaneously. In
the mode, all connection has to use the same serial setting. If one serial setting of
these connections is different from others, the data communication may operate
incorrectly.
There are two operating mode of Multi-access function. One is Normal mode;
another is Round-Robin mode.
Normal mode
Disabling “Response Timeout” parameter, the EKI-152X series will operate in “nor-
mal mode”. When multiple hosts open the serial port simultaneously, the EKI-152X
series only offers control ability for the first connected host and provides data com-
munication function for others. Each serial port supports up to five simultaneous con-
