PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-2 127
A.2.2
Default Values
Almost all commands have initial or default values that are loaded when the PK-232 is first
turned on. The PK-232 assumes these default values to be best suited for the "average"
amateur station operation. There is no rule that says "you must keep the defaults". You
can (and should) change the default values as required for your individual operating
needs, type of equipment, or local customs.
A.2.3 Modes in which the command is used
Many commands work only in a specific operating mode such as packet. Others com-
mands function in all modes. The second line of the command description tells the mode
or modes in which the command functions.
A.2.4 HOST Mode Abbreviations
If you are a computer programmer and wish to write an application for the PK-232, you
may want to consider using the HOST Mode. Information on HOST Mode is available in
the PK-232 Technical Reference Manual.
A.3
Parameters and Arguments
If a command requires Parameters, the type of parameter is indicated after the command
name as well as its default value. Three different types of parameters are used: Boolean,
Numeric and Text or String.
A.3.1 Boolean Parameters
Boolean parameters use one value out of a choice of only two possible values, such as ON
or OFF, YES or NO, or EVERY or AFTER. Boolean parameters can also be toggled with an
argument of "TOGGLE" or "T". This is useful, for example, in the case of RXREV and
TXREV.
A.3.2
Numeric Parameters
A parameter designated as "n" is a numeric value. Numeric values can be entered by typ-
ing them in familiar decimal numbers, or optionally, in hexadecimal numbers (base 16).
When using hexadecimal notation, you must type a $ in front of the number to tell the
PK-232 that this is a "hex" number. Here's a brief explanation of "hex" numbers:
o The "digits" of a hex number represent powers of 16 in the same manner as the
powers of 10 represented by a decimal number.
o The numbers 10 through 15 are indicated by hexadecimal digits A through F. For ex-
ample:
$1B = (1 × 16) + (11 × 1) = 27 (decimal)
$120 = (1 × 16 × 16) + (2 × 16) + (0 × 1) = 288 (decimal)
For numeric parameters the arguments "ON" or "Y" set the parameter value to its default.
Arguments "OFF" or "N" set the value to 0. Baud-rate parameters can use arguments UP
(U) or DOWN (D) to select the next higher or lower baud rate.
