MDS 05-4055A01, Rev. A MDS entraNET 900 System Guide 3

1.1 PRODUCT DESCRIPTION

This manual presents installation and operating instructions for the

MDS entraNET 900 system. The manual is for use by those who will

install, operate, and perform basic maintenance on the radio system.

The entraNET system is an easy-to-install wireless solution supporting

long range Serial and Ethernet data transmission at speeds up to

106 kbps. The system includes an Access Point (AP) transceiver and

two types of Remote transceivers—Serial or Ethernet. These units serve

a variety of network configurations. Figure 1-1 shows each model in the

entraNET family.

Media Access

Control

MDS entraNET transceivers are equipped with a Media Access Con-

troller (MAC) to ensure network access for stations with data to send.

The MAC permits data to be sent from RTUs and other remote devices

on an “on-demand” basis, preventing over-the-air data collisions and

ensuring that the information gets through as intended. MAC function-

ality eliminates the need for active polling of Remotes, a key require-

ment in Report-by-Exception (RBE) applications.

Rugged Packaging

MDS entraNET units are housed in compact and rugged die-cast cases.

They need only be protected from direct exposure to the weather. The

transceivers are supplied with optional flat surface mounting brackets or

35 mm DIN rail brackets, depending on customer requirements.

Simple Installation

Basic installation typically employs an omni-directional antenna at the

Access Point location and a directional antenna at each associated

Remote site. The antenna is a vital link in the system and must be chosen

and installed correctly.

INSTALLATION

, on Page 105 provides guid-

ance on choosing proper sites and antennas.

To establish basic service, you simply connect an antenna, connect an

Ethernet LAN to the AP, a serial or Ethernet device to the Remotes,
