How to use unasigned integers(U8) to select multiple channels

[Exendria]

I'm trying to select more than 1 channel at a time. Right now I can only be on either channel 1 or channel 2, but I need to select both 1 and 2 consecutively. I'm using the "unasigned intergers(U8)" which is connected to the channels wire on a Chroma 6310 driver.

I think what you mean to ask is it possible to program multiple channels simultaneously or concurently (at the same time). The driver uses the syntax :CHAN n as a prefix and unless the instrument itself supports a syntax like :CHAN n,n2 or something similar, then you might not be able to do what you want. I would recomend you look at the instrument's programming manual or contact Chroma. Some instruments allow you to send a series of commands but the instrument doesn't apply them until you issue another command. If you're trying to take a measurement, see if the instrument has a software or external trigger.
