| Time to execute ATWR command (or binary equivalent) | The non-volatile memory is now double protected against data corruption. This ensures reliable non-volatile storage of all parameters. Command now takes 500ms to execute instead of the previous 100ms or less. |
| Modules contain a unique serial number accessible via AT commands. (ATSH, ATSL). | Some systems make use of the radio module serial number for system addresses or inventory purposes. |
| Field updateable firmware | The modules can be reprogrammed with new firmware using PC software provided by Digi. |
| Larger data buffers | Module can now buffer up to 1000 bytes with no need for flow control. Visit Loopback repeater and buffer sizes for more information on buffer sizes. |
