7.3 SDM address
This parameter must be set to use SDM output from the EC100. See SDM output (p. 27) for details
on using SDM output.
Each SDM device on the SDM bus must have a unique address. The IRGASON has a factory
default SDM address of 1, but it may be changed to any integer value between 0 and 14. The
value 15 is reserved as an SDM-group trigger.
7.4 Unprompted output
If the EC100 is to output data as USB or RS-485 (see USB or RS-485 output (p. 28)), this setting
must be set to USB Port or RS485, respectively. The factory default is to disable the unprompted
output and assume data are to be logged via SDM (see
SDM output (p. 27)).
Only one unprompted output type (i.e., USB or RS-485) may be selected at a given time. The rate
at which the EC100 outputs these data is determined by the Unprompted Output Rate setting.
7.5 Unprompted output rate
This setting determines the output rate for unprompted output (USB or RS-485; see USB or RS-
485 output (p. 28)). If the unprompted output is disabled, this parameter is not used. The factory
default output rate is 10 Hz, but it may be set to 10, 20, or 60 Hz.
7.6 RS-485 baud rate
If the unprompted output mode is set to RS-485, this parameter determines the baud rate.
Otherwise, this setting is not used. The RS-485 baud rate defaults to 115200 bps, although the
user may enter another value.
7.7 Analog output
The EC100 has two analog outputs for CO
2
and H
2
O densities (see Analog outputs (p. 30) for
more information). These outputs may be enabled or disabled with this setting. The default is for
analog output to be disabled. Note that the analog output does not include sonic data.
7.8 ECMon update rate
This setting determines the rate at which data are sent over the USB connection to the PC while
running
ECMon . The default setting of 10 Hz should be adequate in most situations.
