TTL serial on GLC24064?

Is the serial connection on the power connector of the
GLC24064 TTL level or regular RS-232 levels? Is there somewhere
on this display where I can hook up a TTL level serial
connection?
Thanks!

You read the manual?
The GLK12232-SM has a TTL mode I think, so definately worth looking
Did read the manual -- it's unclear...

The only mention in the manual of a TTL mode says "see below" and
below is the section on how to use RS-232 via the power connector.
However, I think I'm getting non-TTL signals from the power
connector so I need some clarification...
Thanks,

if you are looking the RS232 chip, and look straight down, there will be two solder jumpers. One is soldered the other isn't, switch them. The bottom left corner of the RS232 chip there is two more solder jumpers like that, unsolder one and solder the other one.
TTL works - yay!
