Communication Format and Flow Control
When using the PE-4000B, set up the communication format and flow control in the unit's BIOS settings. (The communication format and flow control settings defined in GP-Pro EX will be ignored.)
In the BIOS, from the [Advanced] menu's [SCH3106 Second Super IO Configuration], configure [SIO2 COM* Mode] (the asterisk * represents a number 3 to 6) and [Auto Flow Control] to match your communication format. |
