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 geosynchronous 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.
Features
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 (included).
