ON
The COM1 and COM2 Ports Mode have to be changed by SW4 & SW5
respectively. Please refer to below figure the truth table of mode.
Switch ON/OFF type status.
Switch to “ON”, the signal voltage level will be changed to “High”.
Switch to “OFF”, the signal voltage level will be changed to “Low”.
SLEW
0 -> RS-232 to 3 Mbps or RS-485/RS-422 to 20 Mbps
1 -> Logic low input will limit driver slew rate to 250Kbps for RS-232 and RS-
485/RS-422
