Steps in the correct installation of extended user memory:
1) Switch off power supply and remove the cover of the PCD2
2) Plug the additional memory chip into the "USER PROG" socket.
Ensure correct alignment (markings on the socket and the chip must match), and
ensure that all pins on the chip are inserted into the socket
3) Set the jumper next to the socket correctly:
PCD2.M110/M120 hardware version ≥ H
and PCD2.M150

Jumper
J1 (memory type)
J3 (write-protection)
J5 (memory size <= 1
Mbit or > 1 Mbit)
1) Jumper position on delivery: RAM, write-protection deactivated, memory size ≤ 1 Mbit
2) On the PCD2.M110/M120 with hardware version < H, J5 and the J2 F jumper are not present. This means
that where Flash EPROM is used with these controllers, J2 has to be attached to E and only chips up to 1
Mbit can be used for expansion
3) Write-protection only affects the chip in the USER PROG socket
4) Modify the hardware configuration in PG5 accordingly, and download the new configuration
