- The data in a specified block No., set in item 5COMPUTER LINK OUT & SERIAL
OUTPUT on the [OBJECT TYPE I/O] menu, will be output through the computer link. (See
page 11-20.)

* When a Sharp PC is used, a write enable command (EWR) is transmitted from the IV-S20 to
the PC in the following cases.
- When the power is applied to the IV-S20
- 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 serial interface to the computer link
