5.2. COMMAND SYNTAX DESCRIPTION
The Command line shows the required information in bold underlined text . Optional parameters are
shown in bold normal text . The default line shows the parameter values that will be invoked if the optional
parameter(s) are omitted. Many of the commands use control characters which are indicated by a carat
character ‘^’ preceding a letter. (E.g. Control-A is shown as ^A). Other special characters are shown
enclosed in <brackets>. (See section 5.2.1 for a description of the control characters and special
characters and their ASCII values). (All ASCII values are shown in hexadecimal notation). Parameters are
shown in lower case. (See section 5.2.2 for a description of the parameters and their values). All upper
case alphanumeric characters that are not preceded by the carat or enclosed in brackets are to be
interpreted as individual characters. (E.g. F1 is an ‘F’ followed by a ‘1’).
5.2.1. Special Characters
Most commands use control characters to communicate with the encoder. The chart below shows the
designators for the control characters and other special characters that are used in the command
descriptions:
Designator Name ASCII Values (Hex)
^A Control-A 01
^B Control-B 02
^C Control-C 03
^F
Control-F 06
^G Control-G 07
^H Control-H (backspace) 08
^X
Control-X (delete line) 18
<sp>
Space 20
<cr> Carriage Return 0D
<xon> Start transmission 11
<xoff>
Halt Transmission 13
5.2.2. Parameters
Some commands use parameters with variable values. The command descriptions use a generic
designator to indicate these parameters. The chart below shows each of the designators with their
meanings and the permitted values. The values shown are the actual characters to be inserted into the
command message. Normally parameters should be separated from each other by a <sp>.
