Digi 90000566_H manual Table=1..8 applies to master only, Protocol=modbusrtumodbusascii

set ia

table=1..8 (applies to master only)

Defines which table is used to route messages to their destination.

This option applies only to master-attached devices.

protocol={modbusrtumodbusascii}

The protocol being used by the serial device. The serial protocol also affects the implied incoming network master on TCP and UDP ports 2101.

modbusrtu

Modbus/RTU – 8-bit binary per www.modbus-ida.org specification.

modbusasscii

Modbus/ASCII – 7-bit ASCII per www.modbus-ida.org specification.

messagetimeout=100-99999 ms (applies to master only)

When messages are received from remote clients, this option defines the time to allow the message to be answered. This includes both the queuing and slave response delays, and this should be set to slightly less than the timeout of the remote client. After this time, the Digi device assumes the remote client no longer wants a response. The range is 100 to 99999 milliseconds. The default is 2500 milliseconds.

slavetimeout=10-99999 ms (applies to slave only)

After all bytes of the message have been sent to the slave device, this is the time to wait for the first byte of a response. Note that the serial shift times are not included within this timeout. The range is 10 to 99999 milliseconds. The default is 1000 milliseconds.

chartimeout=3-99999 ms (applies to master or slave)

After a first byte is received, this is the time to wait for additional bytes to either consider the message complete or to be aborted. The default is protocol-specific, but usually 50 milliseconds.

idletimeout={0=disabled1-99000 seconds}

The device aborts a connection on the implied incoming master sockets after the remote client has been idle for this time. The time is saved in seconds, and the best use for this timeout is to speed up fault recovery. For example, many wide-area networks can suffer shutdowns without the Digi device detecting it. Using the idle timeout speeds up detection of lost TCP connections. The range is 1 to 99999 seconds. The default is 5 minutes.
