To use USB or RS-485 output, connect a USB or RS-485 cable from the
EC100 to the receiving device (see Section 6.3 ,
Wiring and Connections
(p. 11)
),
and configure the settings (see Section 7 , Settings
(p. 15)
).
The
Unprompted Output
setting must be set to
USB
or
RS-485
.
If RS-485 is selected, the RS485 Baud Rate must be set.
The Unprompted Output Rate must be set to the desired output
rate.
All output data are formatted as comma delimited ASCII. Each record
terminates with a carriage return and line feed. TABLE 8-1 lists the elements in
each output array, and FIGURE 8-1 shows an example USB data feed in
terminal mode.
