use BNC2140 with pci 4461

[Paul82]

Hello,

The old system is a IEPE mic, BNC 2140, and a PCI 4452.

To build a new sound measuring system i use a pci 4461.

I would like to use the one mic and connect the PCI-4461 parallel to the BNC 2140.

In this way i can verify the data with the same signal.

Like this:

              - BNC 2140 -- PCI 4452

              |

mic-------|

              |

              - PCI 4461

The point of  asking is that the BNC2140 is giving a 4 mA signal, and this wil also go to the PCI-4461 and i do not know if this would damage the card.

I hope somebody has some experise on this.

Greetings

Hello,

I am afraid I don't have much expertise in this but was wondering if you can connect pci 4462 to bnc 2140 directly? 

According to the BNC 2140 spec sheet, seems like the 4mA that bnc 2140 is giving off can be disabled in per-channel basis. 

And is there a T shaped cable for the connection you drew below? 

Regards,
