A very lightly used UBS GPR1100 GPS time receiver and frequency generator that's 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. I see output on the RS232(1) port every second using a terminal program so I assume that it has the CMMB output option is enabled. Note that this is not ASCII encoded so will not be useful unless you have a means of reading a CMMB timecode signal. 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 basic web 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 an address range that's different from the current setting. Parameters can also be changed via a serial port on the back panel. But this is a RS-485 type so it cannot be directly connected to a PC's RS-232 serial port - an 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.
