SRG-1150DN / SRG-1250DN / SN-100

1. OVERVIEW

The peculiarity of GMDS S is highly reliable communication by automation and

digitalization.

SRG- 1150DN/SRG- 1250DN with SN- 100 TERMINAL is consists of a MF/HF

transmitter, MF/HF receiver, DSC(Digital Selective Calling) w/k receiver, NBDP

receiver, DSC , distress alarm telephone. All of these are to communicate digitalized

data properly for distress safety and general communication.

1.1 FEATURES

(1) Possible range

Because MF/HF transceiver, DSC W/K receiver, DSC , Distress alarm telephone is

built in SRG- 1150DN/SRG- 1250DN, you are able to use itself without NBDP

terminal. NBDP function works by connecting SN- 100 TERMINAL, but it is not

available to use NBDP TERMINAL only.

(2) Total Control S ystem

SRG- 1150DN/SRG- 1250DN is set up with the major modules combined as one unit

or circuits within a single cabinet. Thus, it is possible to rationalize the total control

system by interlinking the respective module controls.

And Narrow Band Direct Printing is available by connecting NBDP unit(SN- 100) to

SRG- 1150DN/1250DN simply.
