1.1 Overview

The HelloDevice Pro Series allows you to network-enable a variety of serial devices that were not
originally designed for networking. This capability brings the advantages of remote management and
data accessibility to thousands of serial devices over the network.
The PS100 is a versatile single-port serial-Ethernet communication device. The PS200 and PS400 are
two-port and four-port serial-Ethernet communication devices respectively expanding the capabilities
of the PS100. The HelloDevice Pro Series supports RS232, RS422 or RS485 on each serial port
allowing virtually any asynchronous serial device to be accessed over a network.
As for the Internet connectivity, the HelloDevice Pro Series supports open network protocols such as
TCP/IP, UDP and PPPoE (PPP-over-Ethernet) allowing serial devices to be accessed over DSL-
based broadband network or conventional LAN (Local Area Network) environment.
The HelloDevice Pro Series provides the full-featured management functions such as status monitor,
remote reset, error log monitor and firmware upgrade using Telnet and serial console port under the
password protection support. In addition, the HelloDevice Pro Series provides IP address filtering
function to protect unintentional data streams to be transmitted to the serial device, and static key
based 3DES data encryption to promise secure data communication.
The HelloDevice Pro Series was designed to accommodate the unique requirements of the Retail
POS, Security, Industrial automation and Medical marketplaces.
