4. Device Installation and Operation
In order to install the device connect the Router-E to a suitable power supply with the positive supply
in the centre of the plug.
The embedded ETRX2 is in factory default state therefore it will join the first best network which
allows joining. This network can then be used to configure the Router-E over the air as required by
the individual application.
For most applications the default settings will be sufficient and the router can be deployed straight
out of the box with no additional configuration.
Firmware changes and upgrades
The firmware which is loaded onto the integrated ETRX2 Module can be upgraded over the air or via
the serial port, which is accessible using PCB pads after removing the cover.
Please note that level conversion circuitry is required in order to connect the Router-E to a
PC’s serial Port.
In addition to this, access to the SIF programming interface is possible by removing the cover of the
Router-E. You can also use this interface for custom firmware development and real time
debugging of your custom firmware.
Finally with the event of EmberZNet3.x it is now possible to download the Ember EZSP (Ember
ZigBee® Serial Protocol) as described in section 6 of the EM260 manual to the Router-E. In case
you require an Router-E with pre-loaded EZSP firmware please contact
zigbeesupport@telegesis.com.
6. Schematics
The schematic of the Router-E is shown on the next page for reference.
It is identical to the schematic of the ETRX2AP, with the only exception that IC3 is not mounted.
LED1 and the beeper are future options, which are not fitted either. The serial port including the
handshaking lines as well as the reset and A/D2 lines can be accessed via labelled pads.
X2 is the SIF connector, which allows programming and custom firmware development and real time
debugging in conjunction with the Ember InSight Adaptors and the accompanying development
toolchain.
