adnRs232OutSigChanges
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnRs232OutSigChanges
OID (numeric): 1.3.6.1.4.1.637.3.1.4.10.33.2.1.4
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times the output signal has changed from 'on' to 'off' or from 'off' to 'on'. 'NoSuchInstance' is returned in case of the HBCEU board.
What is adnRs232OutSigChanges?
This counter increments each time an output signal driven by the board transitions between on and off states. Network engineers monitor this to detect if the board is cycling control signals too frequently—excessive transitions can indicate software bugs, race conditions, or communication protocol errors. If "Request To Send" (RTS) is toggling 100 times per second, the board's serial port driver is malfunctioning and needs firmware patches or driver fixes.
