Table 10. Internal R-Uim Pinout (J101); Table 11. External R-Uim Pinout - Motorola c18 Developer's Manual

Table 10 provides the internal R-UIM (J101) card-socket pinout.
The external R-UIM interface is wired to the interface connector. Table 11 provides the pinout for the external R-UIM interface.
It is recommended that the total trace length between the board-to-board connector pins on the c18 and the pins of the external
card holder not exceed 100 mm.
Before removing the SIM card or inserting a new one, ensure that the c18 module has been powered down. (See
!
"Turning the Unit On/Off" on page 18.) Otherwise, there is risk of damaging the card or losing data stored on the
card.
