NOTE: the above Mesa Smart Serial (Mesa SS) RJ45 wiring is for the STMBL side, the pinout is not directly mapped/compatible with Mesa's convention! This also means that you can only follow the wire color / pin # convention of either the Mesa or the STMBL, not both. The following is the pinout expected by the Mesa card:
+
NOTE: the STMBL drives do not actually use the VCC/GND connections, they just end up driving differential transceivers (with non-differential signals). The STMBL expects to have a common logic ground with the Mesa card.
