diagnostic information, known as multiplexed (“Mux”) channels. In the 6TD,
three channels are used to report the sensor mass position, one measures the
internal temperature of the digitiser and one is used for the returning
calibration signal (see Chapter 6 on page 72).
The collection and transmission of Mux channels is controlled using the Mux
Channels pane:
If a tick is placed in the check-box next to a channel, its data will be collected
and transmitted as a data stream in GCF format, just as with the normal data
channels. To indicate that the data come from a Mux channel, the Stream ID
will take the form ****Mx, where M stands for Mux and x is a hexadecimal
integer (i.e. 0 – 9, and A – F for 10 through 15). The Z, N/S and E/W Mass
Position Mux channels appear as M8, M9 and MA respectively. ME is used for
the temperature sensor and MB for the returning calibration signal.
5.1.5 Ports
The Baud Rates pane of the Configuration window allows you to program the
baud rate and stop bits for the 6TD's output port.
Caution: If you have a 6TD with Ethernet or Wi-Fi options, the
settings you configure here are used both on the standard data
output port, and on the internal port which sends data to the
Ethernet/Wi-Fi module. If you change them, you will also need to
configure the Ethernet/Wi-Fi module to receive data with the new
settings. This can be done using the Lantronix DeviceInstaller
utility (see section 4.10 on page 32 (wired) or section 4.11 on page
37 (wireless).
