Appendix E
Installation manual to TCS5500 Appendix E ● 93
We will divide the discussion of the commands into two categories.
The first category describes the commands coming from the central
unit and going to the control panel and the second category
describes the commands coming from the central unit and going to
the control panel.
The Commands sent by the central unit and received by the control
panel:
A microphone is activated:
{‘%’}{‘1’}{‘L’}{Microphone number (3)} {CRC (4)}
A microphone is deactivated:
{‘%’}{‘1’}{‘l’}{Microphone number (3)} {CRC (4)}
A microphone goes into request:
{‘%’}{‘1’}{‘D’}{Microphone number (3)} {CRC (4)}
All microphones should be reset:
{‘%’}{‘E’}{‘00’} {CRC (4)}
Acknowledgement of the last received command transmitted by
the control panel:
{ACK}
The commands sent by the control panel and received by the
central unit:
Activate/deactivate a microphone with number … :
{‘%’}{‘1’}{‘T’}{Microphone number (3)}{CRC (4)}
Reset all microphones :
{‘%’}{‘1’}{‘R’}{CRC (4)}
Acknowledgement of the last received command transmitted by
the central unit:
{ACK}
Any other commands sent over the serial channel from the central
unit to the control panel should be ignored.
Examples
If a microphone is activated, and the microphone has the number
‘001’ then the following message is send to the control panel from
the central unit: %1L001013E. The control panel must
acknowledge this command by sending the ACK character back to
the central unit.
If the same microphone is deactivated, then the following message
is sent to the control panel from the central unit: %1l001015E. The
control panel must acknowledge this command by sending the
ACK character back to the central unit.
