Product Description

The GNS165 is designed for mounting on a DIN rail. The front panel integrates eight LED indicators, a terminal block, two DSUB and three BNC-connectors. The receiver is connected to the antenna/converter unit by a 50 Ohm coaxial cable with length up to 70 m (when using Belden H155 cable). The Multi GNSS antennna is powered via the antenna cable.

Pulse Outputs
The pulse generator of the satellite controlled clock GNS165 provides three independant channels and is able to generate a multitude of different pulses, which are configured with the software Meinberg Device Manager. The pulse outputs are electrically insulated by optocouplers or PhotoMOS relays and are available at the terminal block.

Asynchronous Serial Interfaces
One RS-485 serial interface and two RS-232 serial interfaces are available to the user. The corresponding parameters can be set up by Meinberg Device Manager using serial port COM 0.

output level approximately -55 dBm (unmodulated)
Optocoupler outputs 3 optocoupler outputs; UCEmax = 55V, ICmax = 50 mA, Ptot = 150 mW, Viso = 5000 V
the following operating modes are possible for each channel:
- free programmable cyclic or fixed pulses
- timer mode; three 'ON'- and three 'OFF'-times programmable per day and channel
- receiver state; synchronous state of the GNS-receiver is indicated

The switching state of each channel can be inverted, the pulse duration is settable in steps of 10 msec from 10 msec to 10 sec.
The outputs can be enabled either:
- always (immediately after reset)
- only if receiver is GNSS-synchronised
