5. Multiple 8-Relay Addon EMO-R8

Multiple 8-Relay Addon EMO-R8

  • B

    Hi,,

    I have a UniPi 1.1 with 2 x 8-Relay Addon EMO-R8 attached to it.
    In the /etc/evok.conf i've uncommented the extension example below. That didn't work directly, but after reading this: viewtopic.php?f=9&t=123#p307 I've got it working with 1 extension now.

    But now, I've added the params for the second extension, but I cant seem to get those working. Both the extensions are switching together.

    I guess it's a buss address thing, but i don't have any info about those. How should it be then? I've seen this video on youtube: https://www.youtube.com/watch?v=ouRjLepp2SM so I think you guys can help me quickly with this.
    Sharing the evok.conf file in that video would also be nice to have as a refference.

    I'm trying:

    [MCP_3]
i2cbus = 1
address = 0x22

[RELAY_17]
mcp = 3
pin = 7 

etc.. etc..

    Have you switched the address pins on the second extension module to 0x22 according to the table between relay and power connector?

    No I didn't. Where can I find this table? And what should that configuration be then?

    Found it..

    First extension at 0x21 (bus 1) -> address pin: A0=1, A1=0 , A2=0
    Second extension at 0x22 (bus 1) -> address pin: A0=0, A1=1 , A2=0

    But still the table for reference would be nice..
