Description
JP4
(SOT)
2 – 3 closed
SOT4 connected to RS232-Transceiver/SUB-D9
connector on adapter board
JP5
(SIN)
2 – 3 closed
SIN4 connected to RS232-Transceiver/SUB-D9
connector on adapter board
JP11
(URXD)
closed
URXD (receive data SIN4) connected to MAX3232
R1OUT
JP13
(UTXD)
closed
UTXD (transmit data SOT4) connected to
MAX3232 T1IN

If you want to use RS232 signals RTS or DTR to reset microcontroller by programming
software (e.g. FME-FR Programmer) please check the following table for needed jumper
setting:
