The program description
deals with the following:
The device data for a PS2
keyboard can be updated, i.e. programmed, changed or cleared with this
program. Data which has already been stored can also be displayed for
information.
The interface and link to a
processing unit must be defined and the device-specific operating mode set.
Note:
If additional
devices, e.g. magnetic card reader, central lock, waiter lock, etc. are
connected up, the appropriate key codes must be entered in program (PS2
device data format).

information on programming a PS2 keyboard.
The following description
deals with all available options for update of this basic data.
As with nearly all other
programs the following also applies here:
Entry range permitted:
numeric 1 - 999999
First key code for the
start sequence of the device data.
The key code is entered
in this field. This is the code which is sent by the keyboard when a key is depressed.
We recommend that you set the debug level in program PS2
keyboard to 3 or 4
to allow the key code of an unknown keyboard to be ascertained
If debug level = 2 is set the key code for each depressed key will be shown in file "..\work\errlog", in hexadecimal format. The entry of the key code in this program must, however, be done in decimal format.
Entry range permitted:
numeric 1 - 9999
Enter the key code which is
to be sent as the follow-up code by this device. The combination of both codes
defines the start sequence of device data. Often rare combinations such as “Strg-k”, shift-escape”, etc. are sent.
Entry range permitted:
numeric 1 - 9999
Enter the key code which is
to be sent as the end code by this device. In most cases this value is the key
code of the entry key (65293).
If this vale = 0 the value
for the number of key codes which follow the start sequence should be entered
in field length.
Entry range permitted:
numeric 1 - 9999
Number of key code which
follows the start sequence. If the length of the device data is variable, an
end code must be defined.
