USB-2527 User's Guide Installing the USB-2527

Using C40FF-x cables to obtain 40-pin female connectors

In this example, a C40FF-x cable is connected to three of the 40-pin headers (J5, J7, and J8). The result is three

female 40-pin connectors that together have the same signal connectivity as the SCSI connector.

Figure 1. Three C40FF-x cables connected to J5, J7, and J8 40-pin connectors

In all scenarios, a USB cable (MCC p/n CA-USB2.0) is used to connect the USB-2527 to a USB port on the

host PC.

Four-channel TC terminal pin out (TB7)

You can use the TB7 terminal block to connect up to four thermocouples. The first TC channel uses ACH0

(analog channel 0) for its positive (+) lead, and ACH8 for its negative (-) lead. The second TC channel uses

ACH1 and ACH9, and so on, as indicated in Figure 2.
