MANUAL CONFIGURATION
Introduction
A comprehensive set of user-settable operating parameters and programmable function keys
makes the TechTerm suitable for diverse applications. Each settable parameter and
programmable function key has a default value. These values are stored in the terminal's
permanent memory.
This chapter describes each operating parameter in detail, as well as how to set the
parameters and load the default values. Chapter 4 covers programmable function keys.
Parameter Menu Settings
The following section describes the parameters that you can program in a TechTerm. A
summary (
Table 3-1 ) appears at the end of the section.
Baud Rate
This parameter sets the number of bits per second transmitted. The data rate can be set to:
300, 600, 1200, 2400, 4800 or 9600 baud. The default value is 9600.
Data Bits
This parameter sets the number of data bits transmitted per character, either seven (7) or
eight (8). The default value is eight (8).
Parity
This parameter enables/disables the host’s ability to perform error checking on incoming
characters and ensure accuracy. Allowable settings are EVEN, ODD, MARK, SPACE and
IGNORE. The default value is EVEN.
When set to EVEN, ODD, MARK or SPACE, the terminal will perform the corresponding
check on incoming data. When set to IGNORE will still add a parity check bit to each
character, but the value of that bit is indeterminate.
Note: Should the host require a communication setting of 8 data bits with no parity, select
7 data bits and SPACE parity.
