Continuous serial data at 9600bps (above) is encoded as half-cycles of 8kHz (62.5µs long bit) and 16kHz
(31.25µs short bit).
Programming the i9600
In order to use all the functions embedded in the i9600, the user must be aware of the
setup/programming facility, which allow different addresses and frequency channels to be set up, and if
necessary accesses diagnostic test modes.
The i9600 is programmed through the same RS232 port that is used for sending/receiving data. An
RS232 terminal emulator (such as Aterm or HyperTerminal) is an ideal tool.
Terminal program configured with following setup:
To enter program mode, the SETUP pin must be pulled low. In this mode the radio link is disabled,
but characters sent (at 9600 baud, as normal) to the unit are echoed back on the RXD pin.
The unit will only respond to certain command strings:
ADDR0 to ADDR7 <CR>:
Address and channel numbers are stored in volatile memory. On power-up the i9600 reverts to the
default in EEPROM (as supplied this is alw
ays address 0)
SETPROGRAM <CR>:
(these commands are normally only used for factory diagnostics)
NOTONE <CR>:
LFTONE <CR>:
HFTONE <CR>:
# <CR>:
A Carriage Return ‘<CR>’ (00Dhex) should be entered after each command sequence to execute it.
Releasing the SETUP pin to high state returns the i9600 to normal operation.

These commands set up one of 8 unique addresses. An i9600 will only
communicate with a unit set to the same address.
Writes the current address and current channel into EEPROM as the
new default.
A tilda character (~, ascii 126dec) sent by the unit indicates end of
EEPROM write sequence
