[M] Remote Monitoring
The remote monitoring option allows the user to use the REMOTE.EXE to access and 
control the receiver via a modem from a remote location. This option is required for 
GPSTopo
TM
. 
[F] Fast Data Output
This option enables the receiver to be programed to output both raw position data and 
NMEA messages or record data (if a PCMCIA card is present in the receiver) at user 
selectable frequencies up to 10Hz. Without this option, only frequencies up to 5Hz 
are available. 
[T] Point Positioning 
The [T] option allows the user to put the receiver into point positioning mode using 
the $PASHS,PPO command. Point positioning mode will improve the accuracy of an 
autonomous position of a static point.
[3] Observables—1, 2, 3
This option determines the observables available in the receiver where:
 1—CA code and P-code on L1/L2 (No carrier) 
 2—CA code and carrier, P-code on L1/L2 (No carrier)
 3—CA code and carrier, P-code on L1/L2 and carrier 
[J] RTK Rover 
The [J] option allows the receiver to act as a rover station that utilizes the carrier 
phase differential (both DBEN and RTCM message 18, 19, 20, and 21) data 
transmitted from the base to compute differentially corrected positions. This option 
requires the observables option to be 3. For RTCM messages type 18, 19, 20, and 21, 
the U option is required in addition to the J option.
[K] RTK Base
The [K] option allows the receiver to act as a real-time Z base station which will 
output carrier phase differential data. This option requires the observables option to 
be 3. For RTCM 18/19 or 20/21, the B option is also required.
