Mechanical connection uses a two pin locking connector. 1 PPS Interface Specifications: BNC Connector TTL levels into 50 O 10 microseconds-wide pulse with the leading edge synchronized to UTC within 20 nanoseconds (one sigma) in static, time only mode. Rising Time is <20 nanoseconds and the pulse shape is affected by the distributed capacitance of the interface cable/circuit. 10 MHz: BNC connector. Waveform is sinusoidal +12.5 dBm ± 2.5 dBm into 50 O Serial interface: RS-232 through a DB-9 connector Serial protocol: Trimble Standard Interface Protocol (TSIP) binary protocol @ 9600, 8-None-1 RF Antenna connector: BNC Power consumption: 15 watts cold; 10 watts steady state Dimensions: (127mm x 102mm x 40mm) Mounting: Six mounting holes for #6-32 screws. Max. depth 3/8" Weight: (285g)
