2.5  RS-232/422/485 Selection

COM1 to COM2 support 9-wire RS-232 and RS-485 interfaces. COM3 
to COM6 (UNO-2178A) support 4 wire RS-232 and RS-485 interfaces. 
COM A and COM B support 9-wire RS-232/422/485 interface. The sys-
tem detects RS-422 or RS-485 automatically for COM A and COM B. To 
select between RS-232 or RS-485 for COM1 - COM6, adjust JCOM1 to 
JCOM6 accordingly. For COM A and COM B the corresponding jumpers 
for RS-232/422/485 selection are JCOM A and JCOM B.
