Note: *Before enabling the termination resistor, ensure that the device is located at the end of the
interface line.
Function
The RS485 circuit is enabled on UART1. The
UART1 MODEM interface and the Socket
Modem interface are disabled.
The RS485 circuit is disabled on UART1.
Function
The Termination Resistor for RS485_1 is IN.
The Termination Resistor for RS485_1 is OUT.
Jumper J16
The J16 jumper connection controls the selection of the RS485 circuit.
However, UART1 MODEM interface and the socket modem interface are
disabled if the RS485 circuit is enabled. When the shunt is placed, the
RS485 circuit is enabled. See Table 20.
Jumper J17
The J17 jumper connection controls the selection of the RS485 termina-
tion resistor circuit. When the shunt is placed, the RS485 termination
resistor circuit is enabled. See Table 21.
