4.1 ON/OFF of Hardware Flow control
Promi SD101 of version v2g & v2h are designed to use CTS/RTS for handshaking.
For equipment which is not using Hardware flow control for serial communications,
Promi SD101’s firmware should be set to turn OFF hardware flow control (CTS/RTS).
Customers may indicate preferences when ordering or turn off the handshaking by
bridging CTS and RTS (no. 7 and no. 8 lines) using a Gender changer.
Version v3a has automatic detection feature of hardware flow control, but in certain
environment such as with PC, this function may not operate well.
*Starting from Promi SD version v3b, customers may choose the usage of
hardware flow control using PromiWIN software.
