The termination resistor jumper settings should only be selected if the transmitter is the last
device on an RS485 line longer than 200 feet (60 m).
** Or jumper external BTX to BRX and ATX to ARX (same effect as internal jumpers).
To reset communications to 9600 baud, command mode, Custom ASCII protocol, and Address 1,
place a jumper at E1 and power up the transmitter.
