2.3.9 Card ID
This module allows the user to query the card for a card ID. This may be useful for verifying the type
of card in situations where different types of cards are employed.
ReadIO and WriteIO Commands
To read this value the ReadIO command is used with an address of 0xff. The following table shows
the encoding of the bits returned when this function is called:
Address Bit
location
0xFF
0-3
4-7
8-11
12-15
Signals
Major PLD revision: binary coded 4-bit word encoding
the major PLD revision. This value can range from 0 to 15.
Minor PLD revision: binary-coded 4-bit word encoding
the minor PLD revision. This value can range from 0 to 15.
Board revision: binary-coded 4-bit word encoding
the board revision. This value can range from 0 to 15.
Board type: binary-coded 4-bit word encoding the board
type. This value can have one of the following values:
0 - Navigator-ISA family card
1 - Navigator-PCI family card
2 - Unused
3 - Navigator-PC/104 family card
4-15 - Unused
Example
To read the card ID the C-Motion command ReadIO(axis_handle, +0xff, &card_id) is used.
Assuming the value returned is 0x3104, this can be interpreted as:
Navigator-PC/104 card, board revision 1, PLD revision 4.0
C-Motion commands
In addition to accessing these signals using the C-Motion command PMDReadIO, you can use card-
specific C-Motion functions for this purpose. The available card specific functions for this feature are:
C-Motion
command
PMDMBReadCardID
Arguments
axis_handle,
card_ID
Function description
This function returns the card ID, encoded as defined
in the table above.
Connections & associated signals
The Card ID is an internal function of the card. Thus there are no signals directly associated with
this function.
