- Modbus RTU Timing
- The Modbus RTU setting causes the radio to wait for an amount of time, “gathering” data before sending out the radio link.
- With a setting of 0 (Disabled), the radio will send data out its radio link as soon as the data is received into the serial port.
- With a setting of 1, the radio will wait for a number of slots equal to 2 times the Master Packet Repeat setting before sending the received data out the radio link. For example, if Master Packet Repeat = 3, the radio will wait for 6 slots, gathering ...
- With a setting of 2 and higher, the radio will wait for a number of slots calculated by the following formula:
- (Modbus RTU Setting + Master Packet Repeat Setting + 1) x 2
- For example, in a radio where the Modbus RTU setting = 2 and the Master Packet Repeat setting = 3, the radio will wait for (2+3+1) x 2, or 12 slots.
