[e-mail]
Restore Factory Settings
The factory sengs can be restored with the following instrucon: “SET RESTORE ON<CR>”. The Concept1 will
reply with “Please Cycle Power!<CR>”, the output will be muted and the display will show “RESET”. The user must
power o and power on the amplier. During power on, the factory sengs will be restored.
Standby
The amplier can be set in Standby mode with the (oponal) IR remote control or with the SET STANDBY ON
instrucon. Leaving Standby mode can also be done with IR remote controller or the SET STANDBY OFF instrucon.
If an RS-232 instrucon is given when the amplier is in Standby mode or during power on and the amplier is not
ready, it will answer with “STANDBY ON”. Please wait unl the amplier is operaonal.
Power down
During power down, all sengs are stored in the memory of Concept1. Aer this, a string “POWER DOWN!<CR>”
will be send. Depending on how much variables that need to be stored, possible, there is not enough me to send
this complete string.
Errors
The following error strings may be sent by Concept1:
ERROR: Command Unknown!<CR> : Wrong spelling of command or command started with Back Space
character.
ERROR: Unknown Aribute! <CR> : Wrong spelling of aribute.
ERROR: No Header! <CR> : When HEADER is on and ECHO is o, each instrucon must be started
with header. See “RS-232 Sengs”.
ERROR: Unknown Instrucon! <CR> : A command was used with an aribute that does not support this. E.g.
SET SERIAL 0001<CR>
ERROR: Value Invalid! <CR> : A value was out of range or illegal.
ERROR: Zone Invalid! <CR> : No valid zone was specied. Valid zone names are ZONE1 and ZONE2,
without space between ZONE and its number.
ERROR: AMPLIFIER PROTECT! <CR> : See user manual (or appendix)
ERROR: OVER TEMPERATURE! <CR> : See user manual
Appendix
The instrucons SET IPGAIN … and SET SOURCENAME … will write a value to the internal memory of the Concept1.
When these instrucons are given, please wait for the reply or put a delay of at least 100ms aer this instrucon.
The ampliers with Hardware Version number ACPT 1V04 could possible send “ERROR: AMPLIFIER PROTECT!<CR>”
when they are powered o. This is because the sense circuit of the amplier reacts very fast. This doesn’t mean
there is something wrong with the amplier.
