Error Descriptions
Daedalus Lock Manual Spectrospin AG 95
LOCK ErrorOnLCB
Error 4 This is displayed if the CPU, Keyboard or X32 ignore an
error that is detected by the Lock and sent to the CPU.
LOCK Error_Startchar
Error 30 The lock application software is a INTEL Hex file. If the
starting character of any line in this file violates the format
specifications downloading will stop immediately.
To restart the download, reset the BSMS and clear the LOCK
Errormessage #11.(The lock uses only the booteprom, no
valid application software in its program memory).
LOCK FFAError
Error 143 Appears if the DSP FFA is not correctly completed within a
certain time period.
Possible Causes:
- Signal ADC_CONV (L-RX) is not available
- ADC (IC9) on the lock receiver is defect.
LOCK GainBusError
Error 130 Displayed if RF Gain could not be loaded. The
microprocessor on the lock controller board loads the D/A
converter in the Lock Receiver (IC10) via a serial Bus during
a Gain-setting. The microprocessor reads the digital Gain
value back in and compares it with the transmitted value. If
the values are not the same a Gain Bus Error is generated. WR

LOCK HF Power Supply Failure
Error 157 All analog power supplies (LOCK_P15V, LOCK_N15V,
LOCK_P5V and LOCK_N5V) are checked by the
Microcontroller. The supplies are multiplied by a individual
factor and added to a common signal L-RX, IC18).
Possible Causes:
- One or several Supplies missing.
- Some Power Supplies do not fulfil their specifications. MUX L-RX (IC19) Pin

LOCK HWTesterIsOff
Error 50 Function is only available in Hardware Testmode.
LOCK HWTesterIsOn
Error 51 System is not available as the Hardware Testmode is active.
Switch to the normal Mode with ‘Reset’.
LOCK ModeBusError
Error 134 Appears if the Mode could not be loaded. The microprocessor
on the LCB loads the transmitter shift register (IC27) via a
serial Bus using a Mode change (e.g. FFA and Normal Lock
Mode). The mode settings are read into the microprocessor
again and compared with the transmitted values. If the values
differ, a Mode Bus Error is generated. WR

STATUS_DATAR
LOCK No Communication with
DSP
Error 149 This error appears, if the DSP does not clear its host interface
receive registers. Normally, this registers are released after a
read cycle by the DSP semiconductor
Possible Causes:
- Protocol Failure at the Host Bus.
- Control Signals for Host Bus are not generated correctly. LCB:
