To program an IR remote control to
transmit a signal to operate the
Mirage the codes in the table (left)
must be entered.
Note:
There is no discrete Power Off
code, the Power Toggle On/Of must
be used to set the Mirage to
standby.
Power Toggle On/Off will set the
opposite condition of the Mirage as
below.
Mirage On – Power Toggle On/Off
– Mirage set to Standby.
Mirage Off – Power Toggle On/Off
– Mirage set to On.
Command Codes via the RJ12 Connector –
NEC Protocol.
The codes in the table on page 55 are the codes that will be sent to
the Mirage via the RJ12 connector.
The voltage levels that are accepted as an input on pin 2 of the
RJ12 connector (command code from external equipment to the
Mirage) are:
HIGH + 5 VDC LOW 0 V
Important
: When the input on pin 2 of the RJ12 connector is
inactive/idle it must be held
HIGH
. If pin 2 of the RJ12 connector is
held low, all subsequent command codes via the RJ12 connector
and via the Mirage IR receiver (sent from the Mirage IR remote
control) will fail and the Mirage will be non responsive.
Pin 5 of the RJ12 connector is DC ground.
The command codes in the table below are written in the NEC
protocol format. Care must be taken when generating the command
code. The command codes are written as MSB (Most Significant
Bit), LSB (Least Significant Bit). The codes when delivered to the
Mirage must be LSB, MSB.
For the command codes in the table below to work correctly the
format of the NEC protocol must be INVERTED.

The address is 00FF (hex). An example of the ‘Power On’ command
code written in the table – Power On = 00FFD827
An example of the ‘Power On’ command code delivered to the
Mirage via the RJ12 connector – Power On = 00FF8D72 – LSB first.
