The following example will show how the pulse length will be electronically set:

To test if the correct pulse length is set, one can measure LP1 (Data) and LP2 (Clock) at the 8 bit digital Laser port.

To set the pulse length, a signal build out of 4 sent bytes is created.

The following example shows this for a pulse length equal to 200ns.

Byte 1 & 2 are here always the same. The pulse length information will be set within Byte 4. Byte 3 is always zero, except the value of the pulse length can not only be set via Byte 4.

•Byte 1: 0xA5 - 1010 0101

•Byte 2: 0x01 - 0000 0001

•Byte 3: 0x00 - 0000 0000

•Byte 4: 0x200 - 1100 1000

The following image shows the sent signals:

•Channel 0: Opto_Out_2 - Enable

•Channel 1: LP1 - Data

•Channel 2: LP2 - Clock
