[import] What is Level 2 Non-Packet Modulation ?

>>Message imported from previous forum - Category:Trio Data Radios<<

This is a re-posting from the obsoleted (October 2018) "Schneider Electric Telemetry & SCADA" forum.




The E Series licensed radios have a modulation type called 2 level Non Packet mode. This type is chosen under one of two circumstances.

1) The user wishes to communicate using SEL Mirrored Bits protocol. This mode reduces latency to a minimum. (approximately 7ms)

2) The user wishes to use the radio to communicate with MDS 4710B radios. (only the 4710B is supported, no other, but this is a very common type)

Certain features are disabled in this mode:
- Port B
- No Flow Control mode (Hardware Handshaking required)
- Over the air diagnostics (local diagnostics does work)
- Repeat and Translate functions (Store & Forward can be done if an external loopback plug is used)
- 128 bit AES Encryption
- Remote programming
- Collision Avoidance
- Transmit Auto on Data (must use RTS)
