-Synopsis

-Address: 127.127.10.u -
Reference ID: GPS -
Driver ID: GPS_AS2201 -
Serial Port: /dev/gpsu; 9600 baud, 8-bits, no parity -
Features: tty_clk -

-Description

-This driver supports the Austron 2200A/2201A GPS/LORAN Synchronized Clock -and Timing Receiver connected via a serial port. It supports several special -features of the clock, including the Input Buffer Module, Output Buffer -Module, IRIG-B Interface Module and LORAN Assist Module. It requires the -RS232 Buffered Serial Interface module for communication with the driver. -For operation with multiple computers, it requires the ppsclock -streams module described in the Line Disciplines and -Streams Modules page. The streams module requires a gadget box and -1-PPS level converter, such as described in the Pulse-per-second -(PPS) Signal Interfacing page. - -

For use with a single computer, the receiver can be connected directly -to the receiver. For use with multiple computers, one of them is connected -directly to the receiver and generates the polling messages. The other -computers just listen to the receiver output directly or through a buffer -amplifier. For computers that just listen, fudge flag2 must be -set and the ppsclock streams module configured on each of them. - -

This receiver is capable of a comprehensive and large volume of statistics -and operational data. The specific data collection commands and attributes -are embedded in the driver source code; however, the collection process -can be enabled or disabled using the flag4 flag. If set, collection is -enabled; if not, which is the default, it is disabled. A comprehensive -suite of data reduction and summary scripts is in the ./scripts/stats directory -of the ntp3 distribution. -

-Monitor Data

-When enabled by the flag4 fudge flag, every received timecode -is written as-is to the clockstats file. -

-Fudge Factors

- -

-time1 time: -Specifies the time offset calibration factor, in seconds and fraction, -with default 0.0.
-time2 time: -Not used by this driver.
-stratum number: -Specifies the driver stratum, in decimal from 0 to 15, with default 0.
-refid string: -Specifies the driver reference identifier, an ASCII string from one to -four characters, with default GPS.
-flag1 0 | 1: -Not used by this driver.
-flag2 0 | 1: -Set for computers that listen-only.
-flag3 0 | 1: -Not used by this driver.
-flag4 0 | 1: -Enable verbose clockstats recording if set.
