Rugged, accurate and economical, the 1095A/C GPS Industrial Clock Module from Arbiter Systems®, Inc. is the engineer's choice when flexibility, precision and physical durability are required.
The 1095A/C precision time clock is a low cost unit capable of driving common timing signals such as IRIG-B, 1PPS and RS-232 serial time codes, with < ± 100 ns typical accuracy. The compact, rugged enclosure can be mounted in multiple ways, making installation fast and secure. Ideal for outdoor applications, the 1095A/C is capable of performing when other units fail, operating between - 40 °C and 85 °C. Four configurable outputs support substantial drive capability, allowing a single unit to drive multiple loads in parallel.
The 1095A/C maintains the real-time clock, almanac and ephemeris data powered by a back up battery in the case of power loss, reconnecting to the satellite signal in as little as 15 seconds. The built in Event Capture function means the unit records key events related to data received from the input options, with 100 ns resolution.
Choose between the standard internal and optional external antenna to best suit your installation environment.
Model 1095A/C supports front panel options. See photos and Key Features tab below for more information.
- Internal GPS antenna
- Rugged case for outdoor or demanding environments
- Accuracy < ± 100 ns typical; < ± 250 ns worst case
- Four terminal strip connector outputs, three high drive, one analog
- Two RS-232 ports

Windows 10
Windows 10 does not play nice with the 1095_Utility as is. The workaround:
- Download this zip file of the 1095_Utility files 1095utility_v0750.zip
- Compare the SHA256 file checksum
- Unzip the file in an executable location such as Documents
- Find/open the unzipped folder
- Double-click on the 1095.exe
- If there is only one COM port and it is not selectable from the utility then you can manually edit the 1095util.cfg file.
- Close the utility
- Open 1095util.cfg with Notepad
- Scroll toward the bottom - looking for 'port' and 'COM1' (most likely)
- Change the COM1 to the necessary port number
- Save the file
- Open the utility and the correct COM port should be listed. Change the baud as necessary from within the utility. Default is 9600,8,N,1
