Lathem's LTR-GPS is a Global Positioning Satellite receiver using
12-channels to access the accurate date and time signal transmitted
each second by 24 satellites in orbit around the globe.
The system includes an amplified exterior GPS antenna. An integrated
cable links the antenna to an interior receiver module which
retransmits the signal to selected Lathem devices.
The RS-485 output can directly synchronize up to 31 Lathem
time products, up to 4,000 feet away, over a single twisted-pair cat-3
or cat-5 cable. The length of cable and number of synchronized devices
can be further increased using Lathem's SWIFT485+. The supported
devices for synchronization include:
LTR Series Master Clocks (LTR0, LTR4, LTR8)
DDC Series Digital Wall Clocks (DDC2, DDC4)
Sonachron Bell Ringer (DWA-S)
Configuration options include Local Time Zone, Daylight
Savings Time option, and desired output format.
LED's indicate signal reception and protocol mode.
The LTR-GPS can be remotely powered from an LTR-512 Series
Master Clock, using a second cable pair, if the distance is less than
200 feet. Otherwise, power is supplied locally by a 9VAC power adapter
