[Factory setting: Even, 1 stopbit ]
Interframe Space 3.5-25 chars The minimum interframe space between two MODBUS RTU mes‐
sages in sequence (specied as 3.5 characters) is congurable.
Range: 3.5 – 25 character times.

Response timeout 0-25.5 sec. Max. response time.
Used in time critical applications, where low cycle times are re‐
quired. If the response is not ready within the Response timeout,
an exception code 6 (Busy acknowledge) is returned and the re‐
quest must be send again.
[Factory setting: 10.0 ]

without overwhelming its receiver.
