Description
The cnPulse Sync Generator is a GPS synchronization device designed for Cambium Networks PMP and PTP radios. It is weatherproof and can operate in rugged environments. The device can be powered through the radio or through a CAT-5 drop cable, and does not require any configuration or software settings. It has two operation modes, AUX Serial mode and CambiumSYNC In-line mode, and can be used with various Cambium Networks products. The device has an integrated antenna and can track 33 channels. Its timing accuracy is 20ns RMS and its position accuracy is 3 meters. It has three electrical interfaces and requires an 8-pin shielded CAT5 cable for proper cabling.
Cambium Networks cnPulse Sync Generator
cnPulse is the latest GPS synchronization generation device designed specifically for Cambium Networks PMP and PTP radios. The cnPulse module is IP67 (weather proof and supports a wide temperature range for rugged environments. The GPS receiver is highly reliable and supports both GPS and GNSS signals. cnPulse gets it power from the ODU AUX port in mode 1 or from the CAT-5 drop cable in mode 2 so no external power supply is required. There are no configuration or software settings required.
Technical Specification
cnPulse Operation Mode 1: AUX Serial mode (uses cnPulse port 1)
cnPulse derives power input from the radio or CMM port and returns the 1PPS signal and satellite statistics on port 1.
Typically used on CMM5, cnReach and the AUX ports on PMP 450i, PMP450m or PTP 450i
cnPulse Operation Mode 2: CambiumSYNC In-line mode (uses cnPulse port 2 and port 3)
cnPulse is deployed in-line with the radios CAT-5 drop cable. cnPulse receives power (and data) from the ODUs PoEpower injector on port 3.
cnPulse port 2 then outputs PoE+Data+CambiumSYNC to the main input on a radio. Typicallyused on PTP 550.
CambiumSYNC mode: PMP 450i, PTP 450i, PMP 450m, PTP 550, ePMP 2000, ePMP 3000
Aux Serial mode: CMM5, PMP 450m, PMP 450i, PTP 450i
Integrated Antenna:GPS L1, 1575.42 MHz, GLONASS L1, 1598.0625~1605.375 MHz
Tracking Channels: 33 tracking/ 99 acquisition-channel GPS +GLONASS receiver
Update rate: 1 Hz (NMEA)
Timing Accuracy: 20ns RMS
Position Accuracy: 3 meters
Acquisition - Cold Start: 35 seconds (typical under open clear sky)
Electrical Interface
Port 1: AUX PORT RJ-45 8-pin shielded; AUX output
Port 2: PoE + CambiumSYNC ODU RJ-45 8-pin shielded; PoE + CambiumSYNC + Data output
