t4koptions/options.txt

These are the known option codes and their names. The names have been
extracted from receiver firmware, and may not exist on your firmware
version. The descriptions have been extracted from various sources,
including Trimble marketing material.

00: POWER UP PORT SETTINGS

01: POWER UP OUTPUT MSGS

02: LOCATOR OPERATION

03: POWER UP NV ERASE

04: RTCMAsci

05: CyclPrnt

06: POSITION STATISTICS

	Enables a receiver to compute the probable error (“sigma”) in its
	real- time position fixes.

07: TAILBOUY

	Elsewhere in the firmware this is parsed as 'LOW BATTERY OVERRIDE'.
	I don't know what either of these mean.

08: PATHFINDER

09: LandSeis

10: RTCM NETWORK INPUT

11: CARRIER PHASE

	Enables a receiver to measure satellite range by observing (among
	other things) the phase difference between the L1 and L2 carriers.
	This option is less precise than the L2 P-Code Option, but it is not
	affected by Anti-Spoofing. It may be used as a less sophisticated
	alternative to the L2 P-Code Option, or as a fallback when Anti-
	Spoofing is active.

12: HALF CYCLE L2

	A technique for correcting ionospheric delay errors without the use of
	P-code; replaced in recent dual-frequency receivers by the more
	accurate Cross-Correlation Option.

13: MAXWELL L1 ONLY

14: REMOTE DOWNLOAD

	Enables a computer equipped with a modem to download data files from
	an unattended receiver.

15: DEMO EQUIPMENT ONLY

17: RT SURVEY DATA

18: LOCAL DATUMS

19: RSIM INTERFACE

20: DUAL FREQ / MULTI-BIT

21: RS-232 PORTS

	The number of RS-232 ports installed in the
	receiver. Two ports are built in, two additional ports can be
	installed with additional hardware.

22: MULTIPLE DATUMS

23: EXTERNAL TIMEBASE

	Enables a receiver to substitute a very precise external oscillator,
	such as an atomic clock, for its internal quartz-crystal oscillator.
	The EXT-REF BNC jack is only populated on CORS receivers, so enabling
	this option without the appropriate jack is pointless.

24: EVENT MARKER

	Enables a receiver to log a time-stamped record whenever an event (an
	electrical pulse) is detected on a special connector. You can record
	alphanumeric messages associated with particular events; you can also
	generate events from the receiver's keypad.

25: 1 PPS

	Provides a port through which the receiver can output a very precise
	one pulse/second strobe, based on timing information in the satellite
	signals. Other devices can use this strobe as a timing signal.

27: FIRMWARE UPDATE

28: RTCM INPUTS

	Enables a receiver to serve as a DGPS differential station (a rover)
	by inputting RTCM-104 corrections through a serial port from a digital
	radio receiver.

29: RTCM OUTPUTS

	Enables a receiver to function as a DGPS reference station (a base
	station) by outputting RTCM-104 corrections through a serial port to a
	digital radio transmitter.

30: SYNC INTERVAL

	Interval between successive measurements in seconds.

31: NMEA-01

	Enables a receiver to output several types of NMEA-0183 messages
	through a serial port. Other devices can use these messages for
	navigation and similar functions. This option is used primarily in
	marine applications.

32: SV SWAPPING

33: KEYBOARD TYPE

34: NAVIGATION

	Provides an extended set of navigation functions, including a cross-
	track error display and the ability to define and use up to 99
	waypoints.

35: LOCATOR CAR. PHASE

36: KINEMATIC

	Enables a receiver to perform kinematic surveys.

37: Config'd

38: DATA LOGGING SIZE

39: SURVEY TYPE

40: RTK OTF CAPABILITIES

41: IONO-FREE POSITIONING

43: I/O DRIVERS

	Described elsewhere in firmware as JX-1100A DRIVER, presumably the
	Clarion JX-1100A, an early 2.4 GHz spread-spectrum radio modem. This
	option seems to enable the radio config menu in the MODIFY menu.

45: CMR TYPE2 RATE

46: RTK SPECIALS
