Caution
Signals other than RS-232C are also output by the UW/UX series balances
through the RS-232C/AUX connector. If these signal lines are incorrectly
connected, damage may occur to the personal computer or balance. Cor-
rectly connect an appropriate cable for communication between the bal-
ance and personal computer.
Some types of personal computers may not operate normally when con-
nected with the optional RS-232C cable according to the diagram.
