Serial Communication DIP Switch Settings

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):
