Range is 750us to 916us (833us +/- 10%).Word TimeThe word time is calculated from the falling edge of the start bit of the wordpair (address and command byte) to the rising edge of the first stop bit, 18 bitsin total.The stop bits are not counted as part of the word as you can’t count whatdoesn’t change. So the range is 13.5ms to 16.5ms (18 x 833us +/- 10%)When in a Parameters pressing the Menu button will take you to the nextfunction.Interbyte Time Interbyte time in ms:D A L I I N T E R B Y T E T I M E1 2 . 6 m s |
