Digi XBee Application NoteMigration from XBee/XBee-PRO ZB (S2/S2B) to XBee/XBee-PRO ZB (S2C)This guide will assist you with migrating from the XBee/XBee-PRO ZB (S2/S2B) to the XBee/XBee-PRO ZB(S2C) Through-Hole modules. Even though these XBee modules are similar in function, there are somedifferences that you need to keep in mind. The S2/S2B used the Ember EM250 microprocessor tocontrol the ZigBee Protocol. The XBee/XBee-PRO ZB (S2C) module uses the Ember EM357; this newmicroprocessor contains much more memory allowing for more flexibility. The footprint of theXBee/XBee-PRO ZB (S2C) Though-Hole is identical to the XBee/XBee-PRO ZB (S2/S2B) and is fully overthe-air (OTA) compatible. A key change with the XBee/XBee-PRO ZB (S2C) is that six firmware images(Coordinator AT, Coordinator API, Router AT, Router API, End Device AT, and End Device API) arecombined into a single firmware load.Migration ConsiderationsXBee ZigBee (S2) to XBee ZigBee (S2C) Through-Hole ConsiderationsConsiderationsXBee ZB (S2)XBee ZB (S2C) THCommentsIndoor/Urban RangeOutdoor RF line-of-sightRangeup to 133 ft.

The XBee/XBee-PRO ZB(S2C) modules combine these six function sets into a single firmware image. The table below shows youwhich settings to enable on the XBee/XBee-PRO ZB (S2C) modules to match the function set you wereusing on the XBee/XBee-PRO ZB (S2/S2B) modules.XBee/XBee-PRO ZB (S2/S2B) Function SetXBee/XBee-PRO ZB (S2C) Firmware SettingsZigBee Router ATDefault SettingsZigBee Router APISet AP (API Enable) API enabled [1]ZigBee Coordinator ATSet CE (Coordinator Enable) Enabled [1]ZigBee Coordinator APISet CE (Coordinator Enable) Enabled [1]Set AP (API Enable) API enabled [1]ZigBee End Device ATSet SM (Sleep Mode) Cyclic Sleep [4]ZigBee End Device APISet SM (Sleep Mode) Cyclic Sleep [4]Set AP (API Enable) API enabled [1]6
What’s NewThe XBee/XBee-PRO ZB (S2C) introduces some new features and commands such as: An alternative serial port is available using SPI slave mode operationSix firmware images (Coordinator AT, Coordinator API, Router AT, Router API, End Device AT,and End Device API) are combined into a single firmwareo ATCE command (1-enables/0-disables) Coordinator modeo ATSM command (0 is Router/Coordinator, nonzero is sleeping End Device)o Note that Coordinator mode cannot be enabled is SM is nonzero and you can’t set anonzero SM if CE is nonzeroFragmentation is now available in both API mode and transparent modeP3 (DOUT), P4 (DIN), D8 (SleepRq), and D9 (On-Sleep) are now available for I/O samplingBoth pull-up and pull-down resistors can now be applied to pins configured for inputsATVL command added for long version informationATDO command added for configuring device optionsATAS command added for Active ScanSelf-addressed Tx Status messages return a status code of 0x23ATDO has HIGH RAM CONCENTRATOR and NO ACK IO SAMPLING options addedBinding and Multicasting transmissions are supportedAT&X command added to clear binding and group tablesAdded Tx options 0x04 (indirect addressing) and 0x08 (multicast addressing)A 5 second break will reset the XBee. Then it will boot with default baud settings into commandmode.BD range increased from 0-7 to 0-0x0A, and nonstandard baud rates are permitted, but notguaranteedNI, DN, ND string parameters support upper and lower caseTxOption 0x01 disables retries and route repair. RxOption 0x01 indicates the transmitterdisabled retries.FR returns 0x00 modem status code instead of 0x01DC10 - verbose joining mode optionSelf-addressed fragmentable messages now return the self-addressed Tx Status code (0x23)instead of simply success (0x00)Three command characters (" ") typed rapidly will shift the device from API mode to ATcommand modeATCN will shift the device from AT command mode to API mode7
