Does TTL need to be set to 3600 for MX record? - Microsoft Community But the domain is still not getting verified I've hit the refresh button on the 'Domain Settings' page too but to no avail The only issue I'm having is that my domain host does not allow TTL values less than 14400 (4 hours) Thus I'm unable to set the TTL value specified in the instructions on the 'Domain Settings' page - 3600
digital logic - What is meant by TTL in this context? - Electrical . . . Additionally, a user might think that a high signal means "100%", and that a low signal means "0% " Depending on the specific TTL driver, this is not true because of the effective voltages The Chapter "CHANGE THE ANALOG INPUT MODULATION TRANSFER FUNCTION" on page 15 of the linked data sheet shows an example control circuit
what is it TTL which shows on ping report and the value its showing . . . If the TTL value started at, say, 128 and you see a value of 28, then there were 100 hops between the system where the packet originated and the final destination My guess is that the initial TTL for the ping packets was 255, so the first ping traversal took 200 hops and the second took 9
USART, UART, RS232, USB, SPI, I2C, TTL, etc. what are all of these and . . . Often any 5V logic is called TTL, although most circuits nowadays are built as CMOS Today there are also many circuits that work at 3 3V, which is no longer TTL With respect to the internal levels the levels on the RS-232 line are inverted, +12V corresponds to logical low and -12V corresponds to logical high, which can be confusing
