REDGUM RGCD5 Upgrade kit

Allows plug in replacement of NPC SM5813APT with NPC SM5842APT



Preparation

Turn off the RGCD5 and remove the power cord from the rear socket. Remove the 4 screws from the top cover using the Allen key supplied. Locate the NPC SM5813APT Integrated Circuit near where the digital connection wires attach to the circuit board

Removal

Remove the SM5813APT I/C by gently sliding a small screwdriver between the I/C and its socket.

The screwdriver can be inserted under most of the length of the I/C to help pull the I/C upwards. This will help release all pins evenly without stress. Once removed, put the SM5813APT I/C back in the box to return for a credit.

This photograph shows the socket on the "motherboard" now ready to accept the upgrade "daughterboard".

Replacement

The SM5842APT I/C is DIRECTIONAL and should have the ‘half-moon’ shaped symbol on the end pointing to the digital connector (same direction as shown in these photos).

Place the REDGUM RGCD5 upgrade circuit board into the 28pin socket. Make sure that all 28pins line up with the sockets, then press firmly in the center of the I/C until the "daughterboard" looks level and is evenly ‘seated’. Replace the cover and screws. Plug in the power cord, turn on and test.
