Slew Speed Select Jumper
Adjustable Slew Rate for Minimize EMI Error. A slew rate control pin configures
driver outputs for either high data rate or slew-controlled data rates.
Slew-controlled outputs minimize the problems that caused by the reflections
and ringing on long or un-terminated cables. Logical Low input will limit driver
slew from either RS-232 to 1Mbps or RS-485 to 10Mbps.
You can use JP5 (2.54mm pitch) to select High Speed or Low Speed mode.
Auto Power ON Jumper
You can use JP6 (2.54mm pitch) to select to enable or disable the auto power on
function.

password, clear the CMOS data to reconfigure the system back to the default
values stored in the ROM BIOS.
