COM Express® Eval Carrier Type 6
5.12 Serial Interface
The PICMG COM.0 specification defines two optional 2-pin serial interfaces on
COM Express® connector pins A98/A99 and A101/A102 formerly used for 12V VCC
input. Both new interfaces are available directly on optional pin-header J9
and J10.
J9 and J10 allow both interfaces to be used as 2-pin RS232 interfaces COMA
and COMB with Kontron Adapter cable KAB-DSUB9-2. Please check the
documentation of your module if this interface is supported and how to
configure.
