The DS2000-TS's device integration provides investment and operational savings compared to alternative
solutions involving multiple less-integrated devices. Investment savings include both acquisition cost as
well as space allocation and engineering requirements. Power system requirements are consolidated and
simplified, with the DS2000-TS supporting direct feeds from a wide range of DC power sources commonly
used at industrial sites. Operational savings come from reduced maintenance and administration, including
having fewer different software-based devices to coordinate for network configuration, diagnostics and
software upgrades.

The DS2000-TS Terminal Server feature is typically used to enable a host-computer application based on
TCP/IP protocol to communicate with remote industrial devices that have an Async serial network interface
(see Figure 1-2). All communication is in IP-format from the central host to/from the remote site. The
DS2000-TS Terminal Server feature at the remote site disassembles each TCP/IP packet and provides an
Async serial stream to the remote device. In the reverse direction, Async responses from the device are
assembled into TCP/IP packets, appropriately addressed and routed to the host application. More
specifically, all traffic on a DS2000-TS serial interface is mapped to/from an IP address and a specific TCP/
IP port or socket number.
Figure 1-2. Local Terminal Server
There are several variations of the Terminal Server application, described in the following paragraphs.
1.2.1 Local Terminal Server
This is the typical application involving a local IP-host, i.e., a host collocated with the serial devices and
attached to a DS2000-TS port either directly or via a Local Area Network (LAN). The IP host may be a
distributed application server or a PC-based HMI device at the remote site.
