Roll-Up II Interfacing
The following information is not required for normal Roll-Up II operation.
Connecting Roll-Up II to a computer is usually a straight forward process (see Installing
Roll-Up II section in this manual). If you do not have a typical interfacing situation, the
information in this section will offer assistance to setting up the Roll-Up II and connect it to
another device.
The Roll-Up II is equipped to communicate via RS-232C, a widely used serial interface
between computers and peripherals. RS-232C is a (more or less) standard interface, and
cables and connectors are available from a variety of sources. A majority of computers and
peripherals either have an RS-232C interface or can be equipped with one.
A mini-tutorial on RS-232C interfacing
This section provides basic information about RS-232C communications. There are three
areas to consider when using RS-232C:
 Character Format and Baud Rate
 Cabling
 Flow Control
