7 Gently ease the chip’s pins into the socket.
Attention The notch on the chip MUST be on the same end as
the notch on the socket.
Important Series C and earlier PanelView 1200 terminals use two
PROMs as user memory. Series D and E terminals require one PROM to
achieve the same functionality. PanelView 1200 terminals prior to Series
D that have had the logic board replaced may also require only one
PROM depending on the revision of the logic board.
The PanelView 1200 terminal accepts either a 28-pin EPROM or a
32-pin EEPROM. The 32-pin socket in the terminal is large enough to
accommodate an EEPROM, as the following figure shows. If you find it
necessary to put a 28-pin EPROM into the 32-pin socket, be sure to
position the EPROM position the EPROM as far away from the notched
end of the socket as possible.
