Subject: TDT Question From: Larry Feth <feth.1@xxxxxxxx> Date: Wed, 9 Aug 2006 14:25:00 -0400Apparently the TDT User Group is no longer active, so I will ask my question here. Does anyone have software for programming the TDT System II programmable attenuators (PA-4) using the serial port? I asked at TDT and was told that no one who works there now knows how to do it. The instructions in the manual are less than straightforward. Thanks Larry Feth
