Operation
Connect to pin 1, chassis ground, of connected
device.
Output: Connect to receive data pin of
connected device.
Input: Connect to transmit data pin of connected
device.
Output: When you use a modem, connect to
modem RTS pin. The connection sets RTS to true
before transmission. The printer sets RTS to false
after transmission.
Input: When you use a modem, connect to
modem CTS pin. Modem must set CTS true
before the printer transmits data. If not
connected, CTS sets itself true.
To enable communications, connect to signal
ground of connected device. Completes circuit
for all RS-232 signals.
Output: When not using software flow control
(XON/XOFF), connect to input of connected
device (for example, CTS). Indicates printer
mechanical status and status of printer input
buffer.
Input: Serial differential data to the printer.
Output: Serial differential data from the printer.
Input: Serial differential data to the printer.
Output: Serial differential data from the printer.
Output: When you use a modem, connect to
modem DTR pin.
When using Intermec Standard protocol, this
pin indicates that the printer is switched on.
When using XON/XOFF or hardware flow
control, this pin indicates the printer mechanical
status and the status of the printer input buffer.
