3.3. CARD LEVEL FUNCTIONS

Brief

Description

Name

Arguments (in C Syntax)

Full Description

Supply a

‘Card Handle’

to the n-th EN-

EIC-325-PCI

card (if exists).

(First n is 0.)

GetCardHandle

(long* CardHandle,

short CardIndex)

Call this function in loop in your initialization.

Start with CardIndex=0 and increment it each iteration.

Stop the loop upon receiving a ‘failure’ (0) return code from the

function.

For each iteration (denoting CardIndex by ‘n’):

If the n-th EN-EIC-325-PCI card is detected:

* CardHandle is set to a handle to current card, to be used by you

as card’s identifier in all other functions. Save this CardHandle.

In case you have more than one EN-EIC-325-PCI card, use an

array

for the ‘save’ operation.

* Return Code is set to 1 (‘success’).

Otherwise (no ‘fresh’ card detected):

* CardHandle is irrelevant.

* Return Code is set to 0 (‘failure’).

Supply the

Revision ID of

current card.

GetRevisionID

(long CardHandle,

short* RevisionID)

Sets RevisionID to the Revision ID of current EN-EIC-325-PCI

card.

Set a LED

SetLed

(long CardHandle,

short LedNumber,

short OnOffMode)

Turns the specified LED on or off. Useful to check primary

communication with the card. Except when turning both LEDs on,

has no functional significance. Turning both LEDs on has same

effect as RequestPositionCounter (CardHandle, Encoder4, 0),

i.e., simultaneous request for all four axes.

Get a LED

GetLed

(long CardHandle,

short LedNumber,

short* OnOffMode)

Gets the current status (on or off) of the specified LED.

Note: The description of the common arguments is in section 3.6
