3. Factory settings are correct for most installations. If you are using a terminal which
sends serial data on pin 3 of a DB25 connector or pin 2 of a DB9 connector, then set
SW2 ON and SW1 OFF. If you are using a slow baud rate (below 1200) the high
noise filter may reject opening characters as noise. Try setting SW3 ON and SW4
OFF to eliminate noise rejection or use a higher baud rate (1200 to 9600).
4. Make sure center drawer lock is unlocked. (The manual release on the right of the
drawer is always unlocked). Plug in the AC adapter to jack on rear of drawer if your
system requires one. Check everything over one more time.
