UBI EasyCoder 301 Direct Protocol – Programmer's Guide Ed. 1
Chapter 2 Getting Started
Chapter 2
UBI Direct Protocol is stored in two Flash EPROM packages fitted
as standard on the printer's CPU board. No floppy disks or operat-
ing system, e.g. MS-DOS, are required. The printer only needs to
be connected to a mains supply and to a device capable of transmit-
ting 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 program 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 301
Installation and Operation Manual.
It is possible to set up the printer's communication protocol to fit the
host computer, as described in the EasyCoder 301 Installation and
Operation Manual. However, until you have become familiar with
UBI Direct Protocol, it may be easier to adapt the host to the print-
er's default setup parameters. There is no communication setup for
the Centronics parallel interface.
Default serial communication setup on "uart1:"
• Baud rate .................... : 9600
• Parity ......................... : None
• Character length ......... : 8
• No. of stop bits ........... : 1
• Flow control ............... : Disabled
• New line .................... : CR/LF (Carriage Line Feed)
