Troubleshooting
Main Menu Option 4.
Advanced Configuration Screen
Selecting (4) from the Main Menu will display the following:
The EtherPath has a built-in buffer to store data. Most of these settings affect the operation of the buffer
and how data is buffered and transmitted over the Ethernet. The default values should normally be
satisfactory, but they may be "tuned" for optimum operation.
Note
: Options 5, 6, and 7 apply to
Client Mode
only, and have no effect in
Server Mode
.
1. Transmit Timer
When in Timer Mode:
The time period for which data will be stored in the buffer before being sent.
Allowable values range from 1ms to 10,000ms (10 seconds). A commonly used value is 20 msec.
Note: Setting any port's timer to less than 20 ms may cause the performance of other serial ports to be less
than optimal.
When in Idle Timeout Mode:
The time period this unit's port must be idle (after receiving a character)
before sending a block of data via the Ethenet. This is used to keep incoming blocks of data intact. It is
useful for some protocols such as Modbus RTU. Its setting depends upon the port speed, and should be
several character times.. Allowable values range from 1ms to 10,000msec (10 seconds). A typical value for
a 9.6 Kbps port is about 3 msec.
M. Timer Mode
When set to 0
, the timer is a free-running clock and if there is data in the buffer, an IP packet is transmitted
every TIMER msec.
