Installing an mPCIe Mini Card
To have access to the mPCIe slot (Figure 23, pos. 16) please proceed according to the steps described:
1.
Open the device as described in the subsection 5.1 “Opening and Closing the KBox A-103” (step 1-4).
2.
Locate the mPCIe card slot and the corresponding fixing bolts (Figure 23, pos. 16).
3.
Align the notches on the mPCIe card with the notches in the mPCIe socket (J27 or J37). Insert the mPCIe card into
the slot (Figure 23, pos. 16) and rotate it down with the fixing holes of the card over the fixing bolts.
4.
Press the mPCIe card down on the side with the fixing holes and secure it with the available fastening screws.
5.
In order to close the KBox A-103, proceed in reverse order.
To install an mPCIe card into the mPCIe slot (Figure 23, pos. 16), if your KBox A-103 is
equipped with an RS422/RS485 adapter module, you have to remove the RS422/RS485
adapter module (Figure 23, pos. 14), by unscrewing the two fastening screws of the DSUB
connector COM 2 (X204, Figure 10)on the front side of the system. Retain the screws for
later use.
Replace the RS422/RS 485 adapter module, after the installation of the mPCIe card, by
screwing on the DSUB connector COM 2 to the front side with the retained screws.
