SPI Extender multiple SPI signals

[dsa-avl]

Hello everyone,

I’m planning to use some SPI Extenders from Visual Productions and had a question regarding their wiring requirements.

Is it possible to run two extended SPI signals over a single Cat5 cable, or does each SPI extender utilize all twisted pairs within the cable?

Thank you in advance for your assistance.

Best regards,

the extender only use 2 pairs on the Cat5 cable, the one on pins 4,5 and 7 and 8.
So, by doing a special wiring of the RJ45 connectors you can technically use the 2 other pairs for an other SpiExtender.
