About the Digi One IAP
Key Features
The Digi One IAP is high-performance, flexible device server that meets the specific requirements of
the industrial automation (IA) market. It delivers simple, reliable and cost effective network
connectivity for serial devices common in industrial automation applications, such as Programmable
Logic Controllers (PLC), CNC/DNC (Computerized Numerical Control/Direct Numerical Control)
equipment, process and quality control equipment, bar-code readers, operator displays, scales and
weighing stations, printers, vision systems, and many other types of manufacturing equipment.
Features include:
n An industrial-strength, ergonomic enclosure designed to mount on a standard DIN rail
n EIA-232/422/485 switch select ability for use with virtually any device with a serial port, and
expanded supply voltage range of 9-30 VDC with screw terminal connections or the industry’s
first powered Ethernet option (802.3af) that eliminates the need for an external power supply.
n RealPort® COM Port redirection technology
n Easy web-based configuration
n Multi-master capability
n Easy management through SNMP
Flexible Industrial Automation support
The Digi One IAP support for IA protocols is exceedingly flexible, providing connectivity solutions in a
wide variety of industrial automation environments. It supports the following:
n Multi-mastering, which means that a slave using any supported serial port protocol can be
managed by multiple masters; the masters need not use the same network protocol to access
the device server.
n A variety of serial-port protocols, including Modbus ASCII, Modbus RTU, DF1 Full-Duplex,
Compoway/F, FINS, and Hostlink. Support extends to what Digi calls the “user-defined”
protocol, which is any serial protocol that has fixed header and trailer strings that bound all
message packets and where each protocol request is followed by a single response.
n Almost any other IA serial device, master or slave, as long as the device on the other side of the
network can communicate using TCP sockets, UDP sockets, or COM Port redirection (using
RealPort).
