# Collision Avoidance parameters
Collision Avoidance : No #Use Collision Avoidance (N=No, Y=Yes)
CD Idle Time : 10 #0-32000 mSec min idle time before transmit
CD Random Time : 20 #0-32000 mSec random idle time before transmit
CD Time Before Receive : 6 #0-65535 milliseconds before receive
Configure each parameter to work with your application.
Type
Type : M #' '=Disabled, M=Master, S=Slave
This parameter defines the functionality of the secondary port on the module.
M = emulate a DNP master port
S = back-up DNP slave port to the primary port.
Any other value will disable the port.
Baud Rate
Baud Rate : 19200 #Baud rate for port 110-115200
Secondary DNP Port Baud Rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 384
(38400) , 576 (57600), 115 (115200).
RTS On
RTS On : 10 #0-65535 milliseconds before message
This value represents the number of 1 ms increments to be inserted between
asserting the RTS modem line and the actual transmission of the data.
RTS Off
RTS Off : 0 #0-65535 milliseconds after message
This value represents the number of 1 ms increments to be inserted after the last
character of data is transmitted before the RTS modem line is dropped.
Min Response Delay
Min Response Delay : 0 #0-65535 milliseconds before response sent from
slave
Minimum time between receiving a request and transmitting a response. Allows
master time to disable transmitter on an RS-485 network.
Collision Avoidance
Collision Avoidance : No #Use Collision Avoidance (N=No, Y=Yes)
This parameter defines if collision avoidance will be utilized on the primary DNP
slave port.
