PRODUCT DESCRIPTION

MDS Mercury less network service with long range and secure operation at adaptive data rates approaching 12 Mbps. The transceiver is ideally suited for demanding applications in mobile or fixed environments, where reliability and range are paramount.

The product is commonly used to send text documents, graphics, email, video, voice over IP (VoIP), and a variety of other application data between mobile, fixed-point, and LAN-based entities.

The transceiver comes in two primary models—Access Point and Remote, each with unique hardware profiles. Both models support Ethernet and serial services. An Access Point (AP) is a wireless hub that usually provides connectivity into a wired Ethernet LAN/WAN. Remotes associate over the air with an Access Point and are typically connected to an Ethernet or Serial device via a cable.

Series transceivers provide an easy-to-install wire-

INSTALLATION OVERVIEW

There are three main requirements for installing the transceiver—adequate and stable primary power, a good antenna system, and the correct interface between the transceiver and the data device. The Installation Setup Chart (center of this guide) shows a typical Remote installation. Access Point and mobile Remote stations typically use omnidirectional antennas whereas fixed-site Remotes typically use directional antennas such as a Yagi or panel type. Otherwise, both installations are similar.

INSTALLATION STEPS

A typical shipment consists of a transceiver, a power connector and this start-up guide. Below are the basic steps for installing a transceiver. Refer to the tion. You will also find support information at the GE MDS Web site:

www.GEmds.com. Our Technical Services Team is available to assist

with any difficulties that may be encountered. Refer to the back of this guide for contact information.

It is highly recommended that the Access Point unit be installed so that you can quickly check the operation of each associated Remote as it is placed on the air.

Step 1—Mount the Transceiver

Use the supplied 6-32 x 1/4 inch (6 mm) screws to attach the mounting brackets to the bottom of the radio. Figure 1 shows the mounting dimensions of the unit. Mount the radio to a stable surface. (Fasteners not normally supplied.)

EQUIPMENT

DAMAGE

Use only the supplied mounting bracket screws. Screws extending farther than 1/4 inch (6 mm) into the case may cause internal PC board damage.

Step 2—Install the Antenna

To minimize RF interference, the antenna should be mounted at least nine inches (> 23 cm) from the connected device(s), sensors and other external components of the system. Additional information on antenna selection and installation is provided in the

Manual

Install GPS Antenna

Install the GPS antenna in accordance with the manufacturer’s instructions, and connect the antenna cable to the SMB-type connector on the transceiver’s front panel.

Step 3—Measure & Connect Primary Power

The DC input power to the transceiver must be within 10–30 Vdc and capable of continuously providing at least 2.5 Amperes. A power connector with screw-terminals is provided with each unit. Strip the wire leads to 6 mm (1/4 inch). Be sure to observe proper polarity as shown in Figure 2 with the positive lead (

) on the left side; negative on the

right side.

Step 4—Review the Transceiver’s Configuration

There are two key settings that must be known before placing the unit into service:

•

Other parameters commonly needing review or adjustment are:
