Chapter 4 VXI-MXI-2/B Configuration and Installation
© National Instruments Corporation 4-11 VXI-MXI-2 User Manual
The VXI-MXI-2/B can also drive or receive the MXIbus CLK10
signal. Switch S1 controls whether the VXI-MXI-2/B drives MXIbus
CLK10 from the VXIbus CLK10 or receives MXIbus CLK10. As
shown earlier in Figure 4-5c, if W1 is configured to use the MXIbus
CLK10 to generate the VXIbus CLK10 signal, switch S1 must be
configured to receive MXIbus CLK10. This is shown again in
Figure 4-7a below.
If you change the S1 setting to drive CLK10 out the MXIbus, do not set
the W1 jumper setting to receive the MXIbus CLK10; instead use the
settings shown in Figure 4-5a or 4-5b 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 4-7 shows the configuration settings for receiving and driving
MXIbus CLK10, respectively.
a. Receive CLK10 from MXIbus (Default) b. Drive MXIbus CLK10 from VXIbus CLK10
