Chapter 3 VXI-MXI-2 Configuration and Installation

The VXI-MXI-2 can also drive or receive the MXIbus CLK10 signal.

Switch S7 controls whether the VXI-MXI-2 drives MXIbus CLK10

from the VXIbus CLK10 or receives MXIbus CLK10. As shown earlier

in Figure 3-5c, if W3 is configured to use the MXIbus CLK10 to

generate the VXIbus CLK10 signal, switch S7 must be configured to

receive MXIbus CLK10. This is shown again in Figure 3-7a below.

If you change the S7 setting to drive CLK10 out the MXIbus, do not set

the W3 jumper setting to receive the MXIbus CLK10; instead use the

settings shown in Figure 3-5a or 3-5b as appropriate.

Warning: Do not configure more than one MXIbus device to drive the MXIbus

CLK10. Having a second device driving MXIbus CLK10 could result in

damage to the device.

Figure 3-7 shows the configuration settings for receiving and driving

MXIbus CLK10, respectively.
