2.7.3 Small Connector Conversion Adapter for the E1
A small connector conversion adapter for the E1 (R0E000010CKZ11) is separately available from
Renesas for user system boards which are too small to mount the 14-pin connector that is the standard
connector for the E1, E2 and E2 Lite. By using the adapter, you can reduce the area taken up by the
connector mounted on your system.
However, when you use the small connector conversion adapter for the E1, be aware that the pin
assignments of the connector differ from those of the standard interface connector for the E1, E2 and E2
Lite. The pin assignments on the 14-pin connector when the small connector conversion adapter for the
E1 is used are shown in Table 2-4.
The small connector conversion adapter for the E1 can also be used with the E2 and E2 Lite.
