Non-standard Baudrates
Moxa’s UART ASIC, supports most non-standard baudrates in the range 50 bps to 921.6 Kbps. In fact,
supported baudrates are much denser towards the lower values. For example, no baudrates are supported
between the integers 5320 and 5323, but 49 baudrates are supported between the integers 387 and 388. Of
course this is the way it should be, since serial devices that require using non-standard baudrates generally use
slower baudrates.
Before using a serial device that requires using a non-standard baudrate, you must first check that the DA-683
supports a baudrate within the tolerance specified by the serial device manufacturer.
Use the following formula to calculate which baudrates are supported by the DA-683:
(A) Baudrate = 921600/(N+M/8) bps, for N = 1, 2, …, 18431, M = 0, 1, 2, …, 7
or
(B) Baudrate = 8 x 921600/K bps, for K = 8, 9, …, 147456
1-6
