166 Features Communications 166 Com Port #2
Tx Enable Delay
0 mSec
0 2 NA 0 0 1000
• When the control is set for transmit control handshaking, the user may require a delay (in milliseconds) on Com Port #2
between the time when the transmit enable is enabled to when data is transmitted.
• Example: If the transmit enable were used as a keying device for a transmitter or modem, a “warm-up“ period may be
necessary before data can be transmitted.
• For more information, refer to the Advanced Control Features: Communications section of this manual.
167 Features Communications 167 Com Port #2
Tx Disable Delay
0 mSec
0 2 NA 0 0 1000
• When the control is set for transmit control handshaking, the user may require a delay (in milliseconds) on Com Port #2
