Intermec PL4 manual Establishing Communications With a Terminal, Serial Cable Communications

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.
