of only termination characters.
Otherwise, the shared input/output
command buffer of the Model 185/186 may become corrupted.
5.1.3 Serial Communication DIP Switch Settings
The 8 DIP switches located on the rear panel of the Model 185/186 are
used to control various parameters of the RS-232 interface. Switches 6
through 8 control the baud rate of the interface. Switches 3 through 5
control the time interval between data output if the data logger function is
enabled. Switch 2 controls the echo feature and switch 1 enables the data
logger function. Each of these features is fully discussed below.
5.1.3.1 Baud rate control
The Model 185/186 baud rate is controlled by switches 6 through 8 of the
communication DIP switch on the rear panel. The unit is shipped with the
baud rate set at 9600. The switch settings for various baud rates are (on =
1 or the up position):
5.1.3.2 Echo function
The Model 185/186 has an echo feature which is enabled or disabled by
communication DIP switch 2. When the echo function is enabled, the
Model 185/186 will echo the incoming command characters back to the
transmitting device. The echo feature is useful when using an interactive
terminal program on a host computer for communicating with the Model
185/186. The settings are:
