Hardware Installation

Note that, currently, port that uses MOXA Windows NT and 95/98 driver will run at the displayed speed. To be clear, when Smartio C168 Series board is configured as High Speed Spectrum, any port driven by the Moxa-provided Windows NT and 95/98 driver will display the exact working speed. For example, the displayed speed 38.4 Kbps is equal to the working speed 38.4 Kbps.

However, if the port is driven by NON Moxa-provided driver, such as standard serial driver, or Moxa drivers other than Windows NT and 95/98, such as DOS, the real working speed is equal to 8 times of the displayed speed. For example, a port, if set to Normal Speed Spectrum with 38.4 Kbps, will work at

38.4Kbps for sure; while a port, if set to High Speed Spectrum with displayed speed 38.4 Kbps, will actually work at 307.2 Kbps (38.4 Kbps¡Ñ8).

The following is the 8 times speed mapping list for quick reference purpose, particularly for DOS driver.
