For any other baud rates calculate when (at what length) termination resistors are required. This is calculated by dividing the
length L by the ratio between the new baud rate and 19200 or (x/19200) where x is the new baud rate.
( 19200
⁄
)
For example, if new baud rate is 9600
1000
(9600 19200
⁄
)
=
1000
0.5
= 2000
Use termination resistors when cables are longer than 2000 ft.
For example, if new baud rate is 38400
1000
(38400 19200
⁄
)
=
1000
2
= 500
Use termination resistors when cables are longer than 500 ft.
NOTE: Other manufacturers may have different recommendations on wire length and EOL resistor usage.
