A.3 Jumper Settings
The MIC-3840 supports RS-232/422/485 communication modes, which can be
selected using the jumpers on the card. The corresponding chip on the card controls
the serial port's operation mode. Currently, the chip is an F81435AN, and the opera-
tion mode for each port can be controlled individually. The eight jumpers, labeled
J_COM1 through J_COM8, allow you to select the operation mode for each of the 8
ports by adjusting the jumper settings accordingly.
RS-232 mode jumper selection (Default setting):
JCOM4_2,JCOM5_2, JCOM6_2,JCOM7_2, JCOM8_2. The pin indicated
by the
