The ZB2430 has a simple interface that allows OEM Host communications with the transceiver. Table 2 below shows
the connector pin numbers and associated functions.

Test / Sleep Int.
Test Mode – When pulled logic Low and then applying power or resetting, the
transceiver’s serial interface is forced to a 9600, 8-N-1 rate. To exit Test mode,
the transceiver must be reset or power-cycled with Test Mode pulled logic
High or disconnected
Note: Because this mode disables some modes of operation, it should not be
permanently pulled Low during normal operation.
Sleep mode interrupt - When logic Low, forces End Device to wake up from
sleep mode. When logic High, allows End Device to sleep and wake-up
according to specified poll rate. Sleep mode interrupt function available on
End Devices only.

UP_Reset
RESET – Controlled by the ZB2430 for power-on reset if left unconnected.
After a stable power-on reset, a logic Low pulse will reset the transceiver.

I
CMD/Data
When logic Low, the transceiver interprets OEM Host data as command data.
When logic High or floating, the transceiver interprets OEM Host data as trans-
mit data.

O
In Range
When logic Low, the transceiver is associated with a parent and has been
assigned a 16-bit Network Address. The Coordinator will report In Range after
selecting a clear channel to operate.

I
RTS
Request to Send – When enabled in EEPROM, the OEM Host can take this
High when it is not ready to accept data from the transceiver. NOTE: Keeping
RTS High for too long can cause data loss due to buffer overflow.
