• Y-connection setting
To use the Y-connection, turn ON DIP Switch 2-(4) of the DXY-1000 series first and then
turn ON the power switch next. In this condition, all the data is transmitted from the host
computer to the terminal or vice versa without passing through the I/O buffer. At this
time, the DXY-1000 series only transmits the data but does no drawing.
When it receives the ESC.Y or ESC.( command, the DXY-1000 series stores data in the
I/O buffer and starts drawing according to the data Obviously the data being transmitted
here must be drawing data, and they can be output to the terminal. The way the drawing
data are output to the terminal varies depending on the 2nd bit to 3rd bit of the second
parameter of ESC.@ command as shown in Table 5-3 (Monitor mode OFF, monitor
mode 1, monitor mode 2).
The way your computer responds to a request of the DXY-1000 series varies depending
on whether the request comes from an RD-GL I command or a device control com
mand. In fact, it varies from the 2nd bit to 3rd bit of the second parameter of ESC.@ com
mand as shown in Table 5-3. In this condition, data from the terminal can be sent to the
computer. But when the DXY-1000 series is responding to the computer, this response
has first priority and the data from the terminal are ignored.
Also, when it receives the ESC.Z or ESC.) command, the DXY-1000 series returns to the
same condition as before it received the ESC.Y command or ESC.( command.
