The Configuration File
The single parameter to Paylink.exe / AESCDriver.exe is a simple text file, containing a set of
keywords and values that describe the configuration of the Paylink. Line ends are never significant,
and anything on a line after a slash (/) character is ignored.
This section describes the make up of a configuration file. In the following description:
UPERCASE
words represent keywords, which must be spelt as shown, but can be in any case.
[ Optional]
sections are enclosed in square brackets and represent sections that can be
included either to give further details on the item, or to make the “English” read
better.
< Values >
are enclosed in angle brackets. Values can be number expressed in decimal or
hex, or, in some cases, can be pre-defined keywords that map onto numbers. A
string of digits is held to be decimal number, hex numbers can either start with 0x or
end in H.
|
Shows that one of the two values on either side if the symbol
must
be included.
There are three top level keywords:
PROTOCOL
-
Which describes the peripherals connected to the Paylink’s system.
SYSTEM
- Which defines the ways in which the overall running of Paylink is modified.
DRIVER
- Which gives the driver itself details on how it should run.
Note that to help produce configuration files that are readable, there are a few synonyms and
“padding” keywords.
The keywords AT, AND, IS, BY, ON & WITH are all ignored when placed at “obvious” places in the
file.
The keywords BILL, BILLS, NOTE & NOTES are all equivalent, and can be interchanged at will.
The keywords MAX, MAXIMUM & FLOAT are all equivalent, and can be interchanged at will.
The keywords CONNECTOR & PORT are equivalent, and can be interchanged at will.
In general plural keywords are equivalent to singular.
