+Contains an Atheros INT6400A1G.
+
 Pro:
 * Routes the SLAC traffic from RF port to Ethernet, using the original software (INT6000-MAC-4-4-4405-00-4497-20101201-FINAL-B)
 and unchanged parametrization.
 * Works as CentralCoordinator. This means, it sends out "coordinator packets" which enables the connected car to send out the first SLAC message.
+* Works on the PEV side with original software and original parametrization.
 
 Contra:
 * Does not support the read-out of the configuration using the github.com/qca/open-plc-utils.
-* Seems not to be able to send SLAC messages on the RF port.

+Is discussed here: https://openinverter.org/forum/viewtopic.php?p=57003#p57003
+It uses an Atheros AR6400-AC30.
+
+Todo: To be tested...

+The open-plc-utils report the version MAC-QCA7500-2.8.0.30-01-20190707-CS.
 
+Contra:
+- Even with the modified configuration for pev (according to https://openinverter.org/forum/viewtopic.php?p=55120#p55120), the QCA7500 does not send SLAC parameter requests. This means: Cannot be used as pev.

+they write: A Charge Control Module is located under the front passenger seat. It converts the PLC communication from the external charging post into CAN that can be understood by the rest of the car. 
+But: Under the passenger seat, there is the seat control unit:  Hyundai Ioniq Steuergerät Sitz 88196G2200. No other control unit found there.

+there is the discussion, that the PCB is nearly the same between Kona and Ioniq.
+
+In
+https://openinverter.org/forum/viewtopic.php?p=20110#p20110 there is the Kona wiring diagram with pinout.
+
+And for the Ioniq: https://openinverter.org/forum/viewtopic.php?p=20118#p20118. The CP of the CCM connects via a green wire to connector P111.8 (male).
+Also CP is pin7 of the OBC, with a green wire links to pin11 of P52.
+
+In https://openinverter.org/forum/viewtopic.php?p=20132#p20132 there is a foto which shows the unit under the DRIVER seat, below the left guiding rail, screwed on the floor pan.
