Pin Number Signal name Signal direction Function
Input
This signal indicates whether the host computer is BUSY or
READY.
CS1>CS2 indicates that the printer is READY and
CS1<CS2 indicates that the printer is BUSY.
1)When DTR>DSR is selected:
10
11
CS1
CS2
The signal is checked and data is transmitted only when the
host is ready to receive data (READY) (except for
transmitted by DLE EOT or GS a).
2)When XON/XOFF control is selected:
Transmits data regardless of the status of this signal.

Figure 2.1.5 RS-485 Communication data format
“H” indicates:
<Printer transmission data> SD1<SD2
<Printer reception data> RD1<RD2
“L” indicates:
<Printer transmission data> SD1<SD2
<Printer reception data> RD1<RD2
The transmission data is H = 1, L = 0
NOTE: This format is used when the UART for RS-232 is connected to the RS-485 driver.
