Changing the GPIB-232CT-A EPROM (DC Version)
Refer to Figure 4 and complete the following steps to change the GPIB-232CT-A
EPROM.
1.
Turn the printed wiring board (H) so that the underside is facing upwards.
2.
Use the scribe to remove the old EPROM (O) by carefully prying it out of the
EPROM socket (P). Be careful not to put too much force on the EPROM
socket (P) which might cause it to crack.
3.
Notice that the EPROM (O) and the EPROM socket (P) are each keyed in one
corner so that you can only insert the EPROM (O) in one orientation.
Remove the new EPROM from the antistatic bag. Align the new EPROM
(O) correctly with the EPROM socket (P).
4.
Press firmly to ensure that the EPROM (O) is secure in the EPROM socket
(P).
5.
Store the old or original EPROM in the antistatic bag for future use.
