USB-6366 Digitail input ports

[KevWhat]

Hi,

I am trying to input Digital 12bit data(5V TTL) into USB-6366(BNC Model).

According to specification, PFI 0-11 can be utilized. However connector shape are BNC and another ports. It is not convenient. If P0.0 - P0.7 and PFI 8-11 could be utilized, it would be great. Is it possible to do such connection ?

Hi KevWhat

You only can use 2 additional BNC terminal using User 1 and User 2 connectors.

USB-6366 BNC has 24 digital I/O lines (3 port = 8 lines).  The Digital and Timing I/O BNC connectors are only routed Port 1(P1.0 - P1.7). If you connect User 1 and User 2 to any terminals in Screw terminals, They are routed User Access BNC connectors.

Hi Ueno,

Thank you for giving your comment.

Bottom line may be "Screw terminals can not utilize as Digital Input". I expect.
But I don't understand the detail what you explained for Language Barrier.

>If you connect User 1 and User 2 to any terminals in Screw terminals, They are routed User Access BNC connectors.
-> Could you explain the detail? You mean USER1,USER2 BNC ports can be utilized as Digital Input(like D8,D9?).

Best,

I am sorry for the lack of explanation.

Yes, USER1,USER2 BNC ports can be utilized as Digital Input. For example, User 1 screw terminal connects P0.0 screw terminal, User 1 BNC terminal will be P0.0.

If you don't use User 1 and User 2 terminals, you only can use Port 0 (P0.0 - P0.7) and Port 2 (P2.0 - P2.7) in the screw terminals.

Hi,

I understood USER1, USER2 BNC are "Blank Poｒts", thus we can assign another signal on screw terminal. It make sense.

>you only can use Port 0 (P0.0 - P0.7) and Port 2 (P2.0 - P2.7) in the screw terminals.
-> It looks, I can utilize these ports as Digital 11bit input. I will try.

Thanks,
