EMS Wireless Operator’s Manual

EkoLink II

In this section, instructions are provided for organizing the system layout before

installation. The installer or operator must make sure that certain requirements

have been met before beginning installation. In addition, all cables and fibers must

be labeled, and the entire system configuration must be documented. Steps for

this pre-installation set-up are given below.

Frequent referral to the Functional Overview section of the Operator’s Manual with

its detailed photographs will facilitate installation of the system.

1. One optical fiber is required for each Antenna unit; each Hub can connect to

up to four Remote units. Angle-polished SC/APC connectorized optical fiber cable

must be installed in the building. Any optical connector used between the Hub and

the Remote units should be an angle-polished connector specified for return loss

>55 dB. Fusion splices to connect fibers are also suitable. Flat polished

connectors anywhere along the optical fiber path will degrade the system

performance.

2. The customer must provide the following equipment for installation:

(a) Optical connector cleaning kit: cotton swabs, alcohol, dust-free

compressed air

(b) Crimping tool, mating connectors, and pin crimps for the DC

electrical connectors and alarm outputs at the Hub.

(d) Personal computer or laptop with terminal program such as

HyperTerminal.

(e) Volt Meter

3. Not essential, but useful for diagnostics are the following equipment:

(a) RF power meter

(b) Optical power meter

(d) Signal generator

1.4 Power Supply Installation

If purchased, install the power supply and connect power to the Hub. An on-off

switch is located in the rear of the chassis and should remain in the off position until

the installation is completed. Before connecting the Hub or Remotes to the power

supply, apply AC power to the supply and verify the 48 V output with a Volt meter.
