When a Sharp PC is used, a write enable command (EWR) is transmitted from the IV-S30 to the PC
in the following cases.
- When the power is applied to the IV-S30.
- When a write mode nonconformity error (code 10(H)) occurs after a result write command (WRG)
is transmitted (when the power is disconnected from the PC).
-When the output method is changed from the "OUT I/F (PARAL.)" to the "COMPUTER LINK."
