EKI-1528/1526 User Manual 10
2.1.5 UDP Mode (Data Mode)
UDP is used primarily for broadcasting messages over a network. In the UDP server
mode, the EKI-1500 serial device server accesses a max. of 8 hosts’ UDP message.
In the UDP client mode, the EKI-1500 serial device server transmits UDP message to
a max. of 16 hosts simultaneously.
2.1.6 Control Mode
In the control mode, the EKI-1500 serial device server presents a modem interface to
the attached serial device: it accepts AT-style modem commands to connect / discon-
nect to other networking device. If you want serial device running application program
to connect/disconnect to different devices by request, you can use the control mode.
The control mode provides three kinds of modem AT-style commands. The serial
devices can use these commands to control the EKI-1500 serial device server con-
necting or disconnecting to remote networking devices. Thus intelligent serial devices
such as stand-alone PLC will send /receive data to/from devices one by one via
Ethernet.
