User manual - METER SRT-457
rESP
- this parameter defines minimal (additional) delay between the Modbus message
and the answer of the device (received and sent via RS-485 interface). This
additional delay allows the device to work with poor RS-converters which do not
works properly on baud rates higher than 19200. This parameter can be set to one
of values:
Std
- answer as quick as possible, no additional delay
10c
20c
50c
100c
200c
- answer delayed of 10, 20, 50, 100 of 200 chars respectively, where
one character time depends on selected baud rate
In the most cases parameter
rESP
should be set to
Std
(no additional delay).
Unfortunately for some third party RS-converters
rESP
should be adjusted
experimentally. Table 7.1 contains most frequently used values.
