How can I send a serial break longer than 1 second?

My US Digital Encoders require a break length of at least one second. VISA serial break length max is 0.5 second. What do I do?

Hi,

You can use the attribute VI_ATTR_ASRL_BREAK_STATE to manually control the break length. Use the asserted value to set the break and set unasserted to remove it.

Refer to the VISA programmer's reference manual for more details on this attribute.

You can find the manual on your system at the Start manu >> Programs >> National Instruments >> VISA.

Hope this helps.
