An ex-dealer demo UBS GPR1100 GPS time receiver and frequency generator that's never been deployed and which is in close to mint cosmetic condition. The unit has been tested - see screenshots below. The unit has an internal 10 MHz TCXO oscillator which drives four sine wave output feeds via BNC rear panel connectors. There are also four 1PPS outputs. The antenna voltage is 5V so you can use almost any professional grade outdoor antenna (26dB gain or more recommended). The antenna connection is a F-Connector type. The antenna will need to be sited outdoors with a complete view of the sky. Operation behind a window or with an obstructed view of the sky will probably not be successful. The GPS module is a generic 12 Channel Motorola M12+ type (or clone) so it's easily and cheaply replaced or upgraded if the need arises. There's a web management interface (see screenshots below) and the unit ships set to an IP address of 192.168.1.188 so it should be accessible from the most commonly used subnet address range. DHCP is not supported. The IP address can be changed most easily via the web interface - maybe using direct connection via a cross over cable if your LAN uses a different address range. Parameters can also be changed via a serial port on the back panel. This is a RS-485 type so it cannot be directly connected to a PC's RS-232 serial port - a adapter/converter will be needed to convert from 3-wire RS-232 communications to the 4-wire full duplex RS-485 standard. The rear panel RS-485 DB9 connector is wired to a proprietary pin-out (details in the manual) so you will probably need to custom wire a DB9 male connector in order to change the config via the console port (hence the recommendation that you use the web interface for greater simplicity). In my testing I entered the URLs of the config pages in the form http://192.168.1.188/cgi_ipradio?type=1XX where I changed the value of XX to access the different pages (see below). No printed manual is included but a copy may be downloaded from https://www.prostudioconnection.net/2112/UBS_GPR1100_Manual.pdf if required.

Description

Based on a M12MT receiver module, the UBS GPS receiver is a compact, cost effective, GPS locked timing reference.

Designed for applications where 10MHz/1pps clock sources are required to synchronize multiple transmission devices, this module provides an accurate high quality signal set. Multiple outputs enable all base station/site equipment to share a single accurate and stable reference source.

Optionally, UBS GPS receivers provide TOD information via a serial RS232 port, compliant with CMMB standard requirements.

The GPR 1100 unit includes a GPS receiver, as well as a 10 MHz and 1pps distribution system. GPR1100 also includes a controller module, supporting WEB GUI and SNMP interfaces over an Ethernet connection.
