The recommended use of the serial ports on the Acutime 2000 for most users is as follows:

•Use Port B to configure the Acutime 2000 as necessary.

•Disable the automatic output packets on Port B using command packet 8E-A5.

•Use Port B to transmit the desired timing packet.

•Use Port B to query for specific satellite data as needed.

•Use the Port A receive line to time-tag external events or input RTCM data.

If you have two serial ports, use ports A and B on the Acutime 2000 as follows:

•Use Port B to configure the Acutime 2000 as necessary.

•Use Port A to transmit the desired timing packet.

•Use Port B to query for specific satellite data as needed.

•Use the Port A receive line to time-tag external events or input RTCM data.

Port B

Port B is the primary serial port for the Acutime 2000. You can send commands, receive command replies, and query for and receive a variety of satellite data (for example, ephemeris, tracking information, signal levels, and so on) using Port B. You can also receive timing packets that are synchronized with the PPS output on Port B.
