Ok, I got the manual off the shelf - here are the switch settings:

Switches 1 and 2 set the parity:

Switch 1 Switch 2 Parity
Off Off Odd
Off On Even
On Off Mark
On On Space

The other switches are for the other functions:

Switch # On Off
Switch 3 1 stop bit 2 stop bits
Switch 4 50 Hz 60 Hz
Switch 5 Inverse video Standard video
Switch 6* - 12v open
Switch 7* + 12v open
Switch 8 Half Duplex Full Duplex
Switch 9 DTR High Line switch controlled DTR

* - Only applies to terminals with current loop option

Hopefully this is the information you were looking for, let me know if
it helps.
