Command structure falls into one of three groups:
1. Perform a function.
2. Assign a variable.
3. Query a variable.
Perform a Function
A function performs an operation that may or may not display any results. A function may not be
queried. An example of a function is to write the variable settings to flash memory using
rfid:cfg.write CR.
Certain functions that display a value or series of values display the string between curly braces for
easy parsing. For example, the rfid:qid function output displays:
{0x00BB,1,0x0000,80;0x000000801CD1931B2F14}
Assign a Variable
There are three types of variables:
1. Boolean
2. Integer
3. Character
Examples of Boolean Assignments
rfid:op.beep=0
rfid:op.beep=true
rfid:op.beep=False
rfid:op.beep=F
Examples o f Integer Assignment
rfid:out.led=0003
rfid:out.led=3
Note: Some integer values require a 16 bit hexadecimal entry.
For Example: pcProx Plus card types: rfid:cfg.card.type=0xFFFF
Examples of Character Assignment
rfid:Delim.Chr.fac=’:’ CR
rfid:Delim.Chr.fac=’x3a’ CR
