Settings for Communication Parameters
Using a serial (RS-232C) cable to connect the DXY with the computer enables the Auto-Protocol function,
which makes it unnecessary to set communication parameters on the DXY.
Because the DXY can automatically determine communication parameters, plotting can be carried
out simply by downloading the plot data from the computer.
In order for the parameter settings to be made automatically, make sure that DIP switch
[SW2-8]
on the back of the machine is set to
[AUTO.]
Also, if the software is changed while in use, turn the power to the DXY off and then on again to
enable the Auto Protocol function to make the automatic determination of the communication
parameters.
About Auto Protocol
Communication parameters can also be set without using Auto-Protocol, by follow the method described
below.
Setting communication parameters other than baud rate
* These settings are lost when the power is switched off, and must be made again after
powerup.
DIP switch
[SW 2-8]
set to
"AUTO":
8-bit data length, no parity, 1 stop bit
DIP switch
[SW 2-8]
set to
"FIX":
7-bit data length, EVEN parity, 1 stop bit
• Setting DIP switch
[SW2-8]
to
"FIX"
disables the Auto-Protocol function. The parameters in effect
when this is done are a
baud rate (serial transmission rate) of 9600, using and 7-bit data
length with EVEN parity
checking and one stop bit.
• Auto-Protocol can also be disabled by switching on the power while holding down a
position
key
and the
[ENTER]
key. The transmission rate is determined by which
position
key is held down.
Communication parameters other than transmission rate are determined by the setting for DIP
switch
SW 2-8
.
