IMARK   5208L- Link Transceiver

 

5208L Link Transceiver in 19" 3RU Cabinet for installation at Equipment Sites

Imark Stock # 930111

Features:

  • 3RU Cabinet
  • Power Supply with Battery Backup Facility
  • One Kyodo KG108 or KG208 Transceiver
  • Interface/Switching Module for interfacing to other transceivers
  • Full Local Control

 

DESCRIPTION:

The Imark 5208L has been specifically designed to provide a low cost versatile means of connecting a 1-25 Watt mobile radio into a repeater/transponder at radio equipment sites. It is a self-contained unit incorporating transceiver, power supply, and interface/switching module and only requires the addition of an antenna and feeder cable to be operational. It can be supplied with an internal Back-Up battery if required (as an option at additional cost).

The Power Supply Module incorporates an AC Mains SM Power Supply with battery back-up facility and automatic changeover facility. It can be supplied without the Power Supply if required at reduced cost for use at solar powered sites.

The 5208L includes one Kyodo KG108 or KG208 1-25 Watt mobile transceiver and an audio interface/switching module. The Kyodo KG108/208 transceiver is available for any FM frequency between 66 MHz and 520 MHz, have channel capacities of up to 200 channels, and includes CTCSS encoders and decoders that can be programmed for different CTCSS tones on a per channel basis. The RF Power output can be set anywhere between 1 and 25 watts with two fixed outputs being available on a per channel basis. Thus, the transceivers can be pre-programmed with all likely channels, so that the 5208L can be deployed immediately as a stand-by link without wasting time to program the transceivers. The Audio Interface/Switching unit is included to provide the correct audio levels between the link and other transceivers. A DB25 connector is provided on the rear of the cabinet and has I/O's for Busy, PTT, Audio Input, and Audio Output.

The 5208L cabinet is designed for 19" rack mounting and is 3RU in height. The cabinet features all steel construction and is fitted with handles to assist with manoeuvrability and site location.

The Imark 5208L Repeater is normally supplied with the Power Supply, Transceivers for the required frequency band, and the necessary Interface/switching module.
