Where would you like them pulled up to?
There are no pullups as it is on the isolated side of the G540. Pulling them up to the voltage rails on the G540 would negate the optoisolation. The pull ups will need to be on whatever circuitry (breakout board etc) that the outputs are connected to.
Cheers,

When the G540's become available will it be possible to purchase it without the internal G250s? I'd like to get my hands on a set of G250s as soon as they come out but may not if I'm required to buy another set with the G540...
Also noticed on the G540 Schematic dated March 2, 2008 -- no pullup Rs on the ILQ74 for DB25 P11-P13, P15? Has this been fixed or are pullups on the PC side?
Lastly, will the parallel interface port be male or female? I've seen both on some of your prior posts.
