Palm Universal connector (Tungsten T1, T2, T3, etc) has RS232 signals at RS-232 compatible levels, no voltage level translator from TTL to RS232 is needed. You can connect signals from your Palm Universal connect directly to PC or other compatible serial device.
PC-Palm synchronisation cable pinout:
PALM UNI === PC DB9 Female
