HS-21/HS-41X Handheld Reader User’s Manual A-25

Appendices

Reader Settings

The host sets the reader settings using the /, O, P, Q, and = commands and reads them

using the G, ,, and < commands.

For example, the following P command sets register 2C to the value C8.

P(2C)C8

Note: For two-digit setting numbers (i.e., settings 00 through fd), an alternative format may

be used: in place of the parentheses and hexadecimal setting number, substitute a single

character, which represents the setting number. The equivalent to the example above is

P,C8 (the ASCII ‘,’ character has the hexadecimal value 2c). (In certain circumstances,

such as with text commands, “percent-encoding” may be used for encoding a character as

a sequence consisting of the percent character followed by two hexadecimal digits. With

percent-encoding, the example may be expressed as P%2CC8.)

In the Reader Settings Table, the Reg column is the setting number, in hexadecimal, to

be used with the commands identified above. In the Default column, all values are in

hexadecimal unless otherwise specified. To use decimal values in commands you must

precede the data with a pound sign ‘#’. The following P command sets register 2C to the

same value as the example above:

P(2C)#200

Since the single digit values of 0 through 9 are identical in decimal and hexadecimal, no

indicator is needed.

1 2 ... 138 139 140 141 142 143 144 145 146 147 148 ... 171 172
