Establishing Communications With a Terminal
The printer must establish communications with a host terminal
that sends the data to be printed. The PL4 printer provides three
ways to communicate with a terminal:
• Serial cable between the printer and the host terminal
• Bluetooth
™
radio link
• Wireless Local Area Network (WLAN) per 802.11b
specifications
Serial Cable Communications
All EasyCoder PL4 printers can communicate by serial cable.
One end of the serial cable is an 8-pin circular DIN connector
that plugs into the serial communications port on the side of the
PL4 printer. A weather resistant flap protects the
communications port. The connector is keyed to ensure correct
alignment; do not try to force the cable if it does not plug in.
Plug the other end of the cable into the host terminal or the
serial port on a computer as shown in the next illustrations.
Communications between the terminal and the printer are
controlled by the applications running on the terminal and the
printer.
Note: Turn off the printer power before you connect the
serial cable.
Before you can make a serial connection, the serial
communications settings for the terminal or PC must match the
settings on the printer. The next table shows the default serial
communications settings for the printer. The printer must be set
to the default serial settings in order to communicate with
Intermec PLUS.
