EIA (RS-232C) Signals
Frame Ground: FG
Connects to the unit frame and the earth ground conductor of the
AC power cord.
Transmitted Data: SD (TXD) ............................................(output)
Conveys signals from the unit to the printer. A “Mark” condition is
held unless data or break signals are being transmitted.
Received Data: RD (RXD) .................................................(input)
Conveys signals from the printer.
Request to Send: RS (RTS)................................................(output)
This lead is held ‘ON’ whenever DR (DSR) is ‘ON.’
Clear To Send: CS (CTS)...................................................(input)
An ‘ON’ condition of the CS (CTS) circuit indicates that the printer
is ready to receive data from the unit. The unit does not attempt to
transfer data or receive data when the CS (CTS) circuit is ‘OFF.’
Data Set Ready: DR (DSR)................................................(input)
An ‘ON’ condition of the DR (DSR) circuit indicates that the
printer is ready. An ‘ON’ condition 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 signals.
Data Terminal Ready: ER (DTR) .....................................(output)
This signal line is turned on by the unit to indicate that it is online.
The ‘ON’ condition does not indicate that communication has been
established with the printer. The signal line is switched ‘OFF’
when the unit is offline.
