EIA (RS-232C) SIGNALS:
Frame Ground (FG);
Connects to the unit frame and the earth ground
conductor of the AC power cord.
Transmitted Data (TXD);
. . . . . . . . . . . . . . . . ..@Jtpuq
Conveys signals from the unit to the printer. A
“Mark” condition is held unless data or BREAK
signals are being transmitted.
Received Data
(R)(D);. . . . . . . . . . . . . . . . . . . . . . . .
.(input)
Conveys signals from the printer.
Request To Send (RTS);
. . . . . . . . . . . . . . . . . . .((-Jutput)
.
This lead is held ON whenever DSR is ON.
Clear To Send (CTS);..................... **(input)
An ON condition of circuit CTS indicates that the
printer is ready to receive data from the unit. The
unit dose not attempt to transfer data or receive
data when circuit CTS is OFF.
Data Set Ready(DSR);.......................(input)
An On condition of circuit DSR indicates the
printer is ready. Circuit DSR ON does not indicate
that communication has been established with
the printer.
Signal Ground (SG);
Connects to the DC ground of the unit for all
interface signal.
Data Terminal Ready (DTR)...............(output)
This signal line is turned ON by the unit to indicate
that it is ON LINE. Circuit DTR ON does not
indicate that communication has been
established with the printer. It is switched OFF
when the unit is OFF LINE.
Data Carrier Detect (DCD)..................(input)
The ON condition is an indication to data terminal
(DTE) that the carrier signal is being received.

2. If the Panasonic data terminal is a KX-D4985 or KX-D4920 and is connected to the KX-T123211, the default value
of communication parameter is the same a.s that of the KX-T123211.
If the KX-D491 OD is connected to the KX-T123211, set the baud rate of the KX-D491 OD to 1200 baud, the other
default value is the same as that of the KX-Tl23211.
