8.4. XBee ZNet 2.5 Custom Bootloader
This figure show s the orientation of the insight port header.
Table 8‐011.
XBee ZNet 2.5 modules use a modified version of Ember’s boot loader. This bootloader version
supports a custom entry mechanism that uses module pins DIN (pin 3), DTR / SLEEP_RQ (pin 9),
and RTS (pin 16). To invoke the boot loader, do the following:
1. Set DTR / SLEEP_RQ low (TTL 0V) and RTS high.
2. Send a serial break to the DIN pin and power cycle or reset the module.
3. When the module powers up, DTR / SLEEP_RQ and DIN should be low (TTL 0V) and RTS should
be high.
4. Terminate the serial break and send a carriage return at 115200bps to the module.
5. If successful, the module will send the Ember boot loader menu out the DOUT pin at
115200bps.
6. Commands can be sent to the boot loader at 115200bps.
Note: Hardware flow control should be disabled when entering and communicating with the
EM250 bootloader.
