Overview

The PSI-MODEM-SHDSL/SERIAL to Copper Extender transparently extends serial data transmission up to 20 km [12.4 mi] across single twisted pair ( CAT5/6/7 ), coax or any existing copper wiring previously used in alarm circuits, E1/T1 circuits, CCTV and CATV applications.

Long Distance Serial Data Transmission over Copper

SHDSL is the technology of choice for the transmission of digital data over long distance copper wires of a network. Although performance depends on the characteristics of the cable used, the reach of SHDSL is much further than any other DSL technology currently available. In addition, upload and download bandwidth is symmetrical boasting data rates as high as 15.3 Mbps over 2-wire copper and 30 Mbps over 4-wire copper.

The PSI-MODEM-SHDSL/SERIAL to Copper Extender is protocol transparent and supports RS-232, RS-422 and RS-485 interfaces. With two SHDSL ports you can easily set up point-to-point, redundant point-to-point, linear and star topology networks.

Two software configurable digital outputs are available for external device alarm generation.

Although these devices are “plug and play”, should additional device configuration be needed during set-up, power can be supplied via a computer USB cable. The easy configuration software provides online diagnostics, logbook function, individual project configuration and saving of project configurations. Furthermore, to provide on-site technicians with quick device diagnostics, the PSI-MODEM-SHDSL/SERIAL has integrated diagnosis functions, a logbook and clearly visible LEDs.

Long Distance Star Topology Network
The devices are connected via the DIN rail connector(TBUS) in the head station. The DIN rail connector supports RS-485. It can not be used with RS-232 and RS-422. To configure a star topology, you must create several line topologies. In the example below, you must create two linear topologies each comprising of three devices.

Range
The maximum possible SHDSL data rate depends on several parameters. Two important parameters are the cable length and cable cross section. This diagram illustrates the dependency of the maximum SHDSL data rate on the line length with 3 cable types. Longer distances can be achieved using high-quality cables with larger diameters. The PSI-MODEM-SHDSL/SERIAL enables data rates over 2-wire copper from 32 kbps to 15.3 Mbps. Data rates of up to 30 Mbps are possible over 4-wire copper.
