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.
