CODE DESCRIPTION
11 The serial EEPROM memory device failed to acknowledge that it received
data from the processor.
12 The serial EEPROM memory device did not retain a binary data pattern of
01010101.
13 The serial EEPROM memory device did not retain a binary data pattern of
10101010.
14 The serial EEPROM memory device did not contain a correct data pattern at
a particular memory location.
16 A firmware download operation was aborted due to a communications
problem with the host computer or with the serial EEPROM memory device.
The cellular connection may have been disrupted, the host computer may
have experienced problems, or the data that was received was corrupt. The
serial EEPROM memory device may be defective.
18 A segment of FLASH memory could not be fully erased.
19 A segment of FLASH memory could not be programmed correctly.
21 The DCM-200 has been configured to place a CSD call, but there is no
phone number programmed into the unit.
22 The cellular radio will not accept the PIN number. Either the wrong number
was programmed into the DCM-200, or into the SIM card.
31 Problem initializing for a PPP (point-to-point) connection. This error may
indicate a problem with the DCM-200’s operating program. It does not
indicate a problem with the cellular service.
32 Could not negotiate a PPP (point-to-point) connection with the cellular
service. The system may be down or congested. There may have been
data errors that caused the process to abort, possibly due to marginal signal
strength or interference.
33 Could not negotiate a TCP connection to the destination server. This error
is often caused if the destination server is not running (listening) or the
number of server channels has reached a maximum and there are no
channels available. Otherwise the cellular system may be down or
congested. There may have been data errors that caused the process to
abort, possibly due to marginal signal strength or interference.
34 A TCP packet was sent to the server but was not acknowledged as being
received.
35 A TCP packet was received from the server that contained errors or that
was not intended for the DCM-200.
41 The cellular radio could not register itself with the cellular service, either
home or roaming. Signal strength may be too low to establish a connection.
The SIM card may be defective or contain incorrect information.
42 The cellular radio could not detect a cellular service signal. The DCM-200’s
frequency setting may be incorrect for this location or for this service
provider. The distance from the tower may be too great or there is
interference from a nearby building or electrical equipment.
