DTR Startup Mode (DS) setting
|Top Previous Next|
Description (see setting description format info here)
This setting defines the startup voltage of the DTR pin. By default, DTR is LOW* on startup. By changing this setting, you can have DTR set to HIGH* on startup.
DTR Startup Mode is irrelevant when the DTR Mode (DT) setting is 1 (connection status).
* HIGH and LOW states are described with respect to the serial ports of DS100R, DS100B, DS203. For EM100, EM120, EM200, EM203(A) the signaling is exactly opposite.
