Peer Number
Set the number of network device which you want to connect. You can set maximum
sixteen network devices which you want to connect. You need to fill out the IP
Address and Port of network devices which you want to connect.
3.5.3 Control Mode (USDG Mode)
In controlling mode, the EKI-1500 series presents a modem interface to the attached
serial device: it accepts AT-style modem commands to connect / disconnect to other
networking device. If you want serial device running application program to connect/
disconnect to different devices dynamically, you can use controlling mode.
The “Control mode” provides three kinds of modem AT-style commands. The serial
devices can use these commands to control the EKI-1500 series to connect/discon-
nect to remote networking device. Thus, intelligent serial devices such as standalone
PLC will send /receive data to/from devices one by one via Ethernet.
Please refer to the Data Mode (USDG Mode) to setup the Data Listen Port, Com-
mand Listen Port, and Data Idle Timeout.
Hangup Character
The default character is “+”. After you have connected to another serial device via
EKI-1500 series, you may need to disconnect. Then you can use the command "+++"
to disconnect. To do this leaves your keyboard idle (don't press any keys) for at least
several seconds, then press "+" three times. You can set "Guard Time" to define the
idle time. Be sure that you have to press "+" over the idle time.
