DioSetupClkStrobeDelay

Applies To

GX5150, GC5050, GX5050, GX5055, GX5280, GX5290, GX5290e, GX5295, File

Purpose

Returns the Main Clock, Out Clock or Strobe delay value.

Syntax

DioSetupClkStrobeDelay (nHandle, nClock, dDelay, pnStatus)

Parameters

Name	Type	Comments
nHandle	SHORT	GX5150, GC5050, GX5050, GX5055: Master or File board handle. GX5280, GX5290, GX5290e, GX5295: Board or File board handle.
nClock	SHORT	Clock/Strobe can be as follow: 0 CLK_DELAY: Main Clock. 1 USER_CLK_DELAY: Out Clock 2 STROBE_DELAY: Strobe 3 BOARD_OFFSET_DELAY (Gx528X /Gx529X only): Additional offset that advance or delay the specifed DIO board’s Clock and Strobe. The offset values can be set between -3.0 nSec to +3.0 nSec with resolution of 0.25nSec. The main purpose of this delay is to ease timing alignment between DIO boards in a domain.
dDelay	DOUBLE	Delay values are in nSec GX5150, GC5050, GX5050 GX5055 Out Clock and Strobe: 0.0 to 64 nSec with increments of 0.25. GX5280/GX5290/ /GX5290e/GX5295 Main Clock: and Strobe, any of the following values ranges: 0-3 ns with increments of 0.25 ns. 4-7 ns with increments of 0.25 ns. 8-11 ns with increments of 0.25 ns. 12-15 ns with increments of 0.25 ns. 16-19 ns with increments of 0.25 ns. 20-23 ns with increments of 0.25 ns. 24-27 ns with increments of 0.25 ns. If nClock = BOARD_OFFSET_DELAY (Gx528X /Gx529X only): -3.0 to +3.0 ns with increments of 0.25 ns.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

Comments

The function adds a delay between the timing board clock source (i.e. programmable clock) and the following clocks:

0. Main clock that stimulate the DIO.

1. Out Clock signal (timing connector).

2. Strobe Clock signal (timing connector).

3. Board offset delay.

Note: For the GX5280/GX5290/GX5290e family when running at frequencies above 100MHz only 0-3nS delay range is available.

Example

The following example sets the main clock delay value to 15 nSec:

SHORT nStatus;

DioSetupClkStrobeDelay (nMasterHandle, 0, 15, &nStatus);
