Maximum Intercharacter Delay (MD) setting

Top  Previous  Next

 

Description (see setting description format info here)

 

Function:Defines the maximum time gap between two consecutive characters recorded into the serial-to-Ethernet buffer, exceeding which will trigger a break condition

 

Set (S) command format:SMDddd, where ddd is the time gap in the 0-255 range (0-2550 ms), value of 0 deactivates break condition generation on time gaps

 

Get (G) command format:GMD

 

Init (I) command effect:Initialized unconditionally, through network command, serial command, or quick initialization

 

Post-initialization value:1 (10 ms)

 

Change takes effect:After reboot or exiting the serial programming mode

 

Overriding parameter:---

 

Relevance conditions:---

 

First introduced:Earlier than "baseline" V3.14/V3.51

Details

 

Maximum Intercharacter Delay defines the maximum time gap between two consecutive characters recorded into the serial-to-Ethernet buffer, exceeding which will trigger a break condition. Break conditions are related to routing the data in the serial-to-Ethernet direction. See serial-to-Ethernet data routing for more information.

 

Intercharacter delay can be set in 10 ms increments. Delay tracking is disabled when Maximum Intercharacter Delay is set to 0.

 

Intercharacter delay is not counted when the Flow Control (FC) setting is 1 (enabled) and the DS is holding the RTS line in the LOW* state thus indicating to the attached serial device that the DS is not ready to receive the data. This is done to prevent the DS from generating the break conditions on time gaps caused by the DS itself.

 

* 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.
