5.1.3.3 Data logger function
Switch 1 of the communications DIP switch controls the data logger
function. The unit is shipped with the data logger function disabled. This
feature is normally used with a printer rather than a host computer, since
a computer can be more usefully programmed utilizing the available
command set. The data logger function generates a time relative to
instrument power-up and a corresponding level. The units of the level
output are set by the units mode toggle switch. The time and
corresponding level are formatted and output to the host device at regular
intervals as specified by the switches 3 through 5. The settings for the data
logger function are:
The host device can be a standard dot matrix printer connected via a
serial-to-parallel converter, or connected directly with a printer capable of
receiving serial data. Presumably, any serial-to-parallel converter which
can be properly configured is acceptable. AMI has tested the Model 185/
186 with a standard, low cost converter configured as a DTE device, 8 data
bits, no parity, and 1 stop bit. In order to communicate with the host
device, it is necessary to set the Model 185/186 to the identical baud rate of
the host device.
5.1.3.4 Data logger output interval
The interval between successive output from the data logger function is
controlled by switches 3 through 5. The unit is shipped with the data
logger function
disabled (see above). The available intervals and the
corresponding switch settings are (on = 1 or the up position):
