NI USB-8451 communication with another USB-8451 (SPI/I2C)

[Yaamamoto]

Hi guys

I have question about communication between two cards. In one topic I found that the card does not support the slave mode, but the last post there is from the year 2013, so if anything has changed since then ?? and if it still does not support the slave mode, how can I start the communication between 2 masters ?

Thank you for answers

The USB-8452 can be a slave I2C device.  But neither of the 845x devices and be a SPI slave.
