If the I m done indication was sent early the application might then do it s subsequently action too early Another possibility is that the application is using the timing of the I m done message to determine the baud rate For example if the serial port was using external clocking the application might not know what baud rate was being used so it would send a message and see how long it took The early delivery of I m done could screw up its calculation There are many other communication protocols in which time periods are counted from the point that message has been delivered Any time you change the timing of the I m done indication you run the risk if interfering with such protocols What Should Use There are various way to configure Tx Ack Advance Following is a discussion of some possibilities None If you re using a baud rate of 9600 or less you probably don t have a problem The 1 millisecond delay will not significantly affect your throughput and you can select this option This option is also a good choice if you are running an application in which throughput is not an issue or one in which guaranteeing 100 correct operation is important enough that you d prefer not to risk having problems Auto The Auto setting uses that calculation described above when internal clocking is used and sets the Tx Ack Advance to None when external clocking is used this is because the host does

20. it were sent early could arrive at the host a significant amount ahead of time As a result the application might use the I m done signal as an indication that the remote end is ready leading to various kinds of trouble 20 7 1 f TX ACK Advance Data flushing Sometimes an application will issue a transmit flush command to the adapter to get rid of extra data For example let s say an application sends AAAA to the adapter and then once it s received the I m done indication sends BBBB Now let s say that sometime after sending BBBB the application decides to cancel whatever part of the BBBB has yet to leave the serial port and sends a transmit flush command to the adapter If the adapter had been lying about being done sending AAAA it might still not be done and the flush could purge the transmit FIFO of some of the A s which is not what the application was expecting in addition to the B s Timing In some applications the receipt of the I m done indication is used as a timing reference point For example an application could send a data stream like this COMIMIAND 3 ssciestesGeresasecepertatortvepeccauneatiniveiertiseut The extra periods following COMMAND would be just used to establish a timing interval the application would know that once the serial port said I m done the receiver would have had at least 64 character times to process COMMAND
21. n t know the baud rate when the clocking is supplied externally Experiment If you re using a baud rate above 9600 you can simply try increasing the Tx Ack Advance setting and see whether it improves performance Qin which case great causes problems in which case don t use it or doesn t make any difference in which case it doesn t matter what you do 21 7 1 f TX ACK Advance Calculate If you know that your application will not run into trouble with flow control or data flushing you know what baud rate it uses and youd like to adjust the Tx Ack Advance to most closely approximate the timing of a built in port you can calculate the value yourself using this formula Integer baud totalBitsPerCharacter 1000 0 5 This will result in the host receiving the transmit complete message at approximately the same time the last character has actually been transmitted Note the total bits per character include the start bit the stop bit s the parity bit if any and the data bits So an 8 bit character with one stop bit and no parity has a total of 10 bits 2 Year Limited Warranty TRIPP LITE warrants its products to be free from defects in materials and workmanship for a period of two 2 years from the date of initial purchase TRIPP LITE s obligation under this warranty is limited to repairing or replacing at its sole option any such defective products To obtain service under this warranty you mu
