4. Troubleshooting

*Full FAQ list will be released soon by mid of July, 2003. Below are key information

customers need to know using Promi-SD™.

4.1 ON/OFF of Hardware Flow control

Promi-SD101 and Promi-SD102 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-SD101/102’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.

*Starting from next version of models, Promi-SDs of version v2i and higher, will

have automatic detection feature of hardware flow control so can be used,

WITHOUT a gender changer to control CTS/RTS, for any type of

devices/equipments.

4.2 Enabling/Disabling of Response Signals

-OK, CONNECT, DISCONNECT & ERROR

Promi-SD™ will respond to users on the current status, success & failure of

connections, and error mode. Both PromiWIN™ and Terminal Programs will receive

related response signals from Promi-SD™.

In some cases, various equipment may regard these four response signals incorrectly

and react inappropriately. To avoid these possible errors, users may disable the

response signals via PromiWIN™ or AT commands at Terminal.

1) By Promi-WIN™, check OFF at Signal pane at Device Setting panel to disable 4

response signals from Promi-SD™.
