EasyCoder E4 Direct Protocol v2.10 – Programmer’s Reference Manual

Chapter 2
Intermec Direct Protocol is stored in two Flash EPROM pack-
ages fi tted as standard on the printer’s CPU board. No fl oppy
disks or operating system, such as MS-DOS, are required. The
printer only needs to be connected to an AC supply and to a
device capable of transmitting characters in ASCII format, which
can be anything from a non-intelligent terminal to a mainframe
computer system.
For running the printer, we recommend a computer with a
screen, an alphanumeric keyboard, and a communication pro-
gram which provides two-way communication via an RS 232C
serial port. A Centronics parallel port can also be used, but it will
provide one-way communication only: no data or messages can
be returned to the screen of the host.
Connect the printer and host as described in the EasyCoder E4
User's Guide.
It is possible to set up the printer’s communication protocol to
fi t the host computer, as described in the EasyCoder E4 User's
Guide. However, until you have become familiar with Intermec
Direct Protocol, it may be easier to adapt the host to the printer’s
default setup parameters. There is no communication setup for
the Centronics parallel interface.
Default serial communication setup on ”uart1:”
• Baud rate:
9600
• Parity:

• Character length: 8
• No. of stop bits:
