There are two types of KDU's. One has a RJ45 connector for use with the EPL portable printers such as the Transport or Xport. The second has a 9 pin serial connector for use with the desktop EPL printers with a serial port available.
The printer communication settings must be set to 9600 Baud, No Parity, 8 data bits, 1 stop bit. The KDU has an auxiliary port for connecting items such as scanners or scales. This device must be set to 4800 Baud, Odd Parity, 8 data bits, 1 stop bit.
For G Series Printers there is a adapter for the KDU Part #105850-026.
The KDU cannot send EPL to the printer. It is only capable of entering basic text in response to prompts from the printer. The format below is a simple example of a label format that can be downloaded to the printer. It will prompt the KDU for information to complete variable fields in the format.
