2.1.2 Serial Architecture

The ADAM-4579 provides two modes to meet your needs. One is

command mode; the other is data mode. You can use it according to

your application.

2.1.2.1 Data Mode

The Data mode provides a certain amount of transparence and

flexibility in transmitting data between two devices. If you wan to

transmit data to any networking device from serial device directly, you

can select data mode.

In data mode, the data from the serial port of one ADAM-4579 can be

automatically sent to the other networking device, without the need for

an intermediate PC. Thus, serial devices will be no longer bundled with

operation system and behave like network devices to send /receive

data via Ethernet.

2.1.2.2 Controlling Mode

In controlling mode, the ADAM-4579 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 controlling mode provides three modem AT-style commands. The

serial devices can use these commands to control ADAM-4579 to

connect/disconnect to remote networking device. Thus, intelligent

serial devices such as stand-alone PLC will send /receive data to/from

devices one by one via Ethernet.
