responding to each side.)
STR-LSA1 have 63 links and no more links can be estab-
lished.
2 Reserve error Unable to reserve
(Note that there are two types of errors cor- (Specified device is already reserved and cannot be con-
responding to each side.) trolled.)
3 EMPTY When an empty packet has been received after establishing
a link.
(This problem occurs when the opposing playing is not in
operation, when an MD is used to select input for a CD which
is not being replayed, and when a CD is not being replayed
when recording from a CD to an MD.)
4 Invalid format This problem occurs when a signal in a separate format (i.e.,
a signal which cannot be replayed) is detected (i.e., when
recording to an MD when the channel is being used for DV
signals).
5 UNLOCK Invalid signal clock detected at a time when i.LINK IC PLL
is not locked.
(This error occurs when connected to a unit with improperly
designed output signal circuits.)
6 NO SIGNAL No input signals detected at a time when i.LINK device has
been selected.
(This error occurs when no input signals are detected after
switching from optical input to i.LINK input.)
7 NO SIGNAL No input signals detected in i.LINK mode.
(This problem occurs when the power of the opposing unit
is turned off after linking.)
8 Unable to output signal Unable to interrupt output because bus is being used to ca-
(No ISO resource found) pacity.
(This error occurs when multiple DV signals are being out-
put and the bus is too busy to generate an interrupt.)
9 LOOP A group has been created as a result of i.LINK cable con-
nections.
10 Bus reset generation Bus reset has been generation.
(This occurs when a new device has been connected or a
device has been disconnected.)
11 Bus reset generation during recording Bus reset has been generation during recording.
(This occurs when a new device has been connected or a
device has been disconnected.)
Note 1 : i.LINK messages displayed only in upper-case characters.
Note 2 : Distinctions between "No signal" and "Cannot link" messages made by C code.
Note 3 : Note that No. 9 may not always be properly detected.
Comment 1 : As before, a "Can't copy" message is displayed when it is impossible to record because of SCMS restrictions.
Comment 2 : C code C78 represents an improper connection (i.LINK connection).
Examples of causes of errors Display on next model
Unit establishing link: Cannot link
Unit being linked to: Cannot link
• When an attempt is made to establish a link from device A
(i.e., a PC) to device B, and a link cannot be established
between device A and device B because device B is al-
ready linked to another device C, "Remote" will be dis-
played on device B and a "Cannot link" message will be
displayed on device A.
• When an attempt is made to establish a link from device B
(i.e., an MD) to device C (i.e., a CD) and the CD is already
linked to another device D (e.g., an MD), a "Cannot link"
message will be displayed on device B and a "Remote"
message displayed on device C.
Unit establishing link: Cannot link
Unit being linked to: Cannot link
• When an attempt is made to establish a link from device A
(i.e., a PC) to device B, and a link cannot be established
between device A and device B because device B is al-
ready linked to another device C (e.g., device C), "Remote"
will be displayed on device B and a "Cannot link" mes-
sage will be displayed on device A.
• When an attempt is made to establish a link from device B
(i.e., an MD) to device C (i.e., a CD) and the CD is already
linked to another device D (e.g., an MD), a "Cannot link"
message will be displayed on device B and a
"Remote"message displayed on device C.

Display mode Description of C code
C78: 11 • Remote device Link.
(When i.LINK device has
been selected)
C78: 12 • Hone device Link.
(TUNER, ANALOG)
Device to which an attempt was made to establish a link is
already linked (i.e., connected) to another device.
C78: 16 • Remote device reserved
C78: 17 • Home device reserved
Device to which an attempt was made to reserve the device
has already been reserved by another device.
C78: 21 • Waiting for input
State in which link has been properly established (i.e., sig-
nals may be transmitted over bus) but no signal has yet been
sent.
C78: 22 • An attempt has been made to transmit a signal over a broad-
cast channel.
Sony DVs are designed to allow the use of 63 channels. MDs
also have the same design, and it is impossible to use the
same channel after it has already been used (i.e., the same
channel cannot be used again without the ability to obtain
channel authorization).
C78: 31 • Unable to perform clock synchronization
The remote device has been poorly designed and communi-
cations have reached the limit of stable PLL (where the PLL
is a chip used to stabilize the clock). Home device okay; fault
lies with remote device.
C78: 04 • No input signal
(Used for units able to perform i.LINK switching without
linking.)
C78: 23 •No input signal because remote device not powered on
(Used for units requiring linking for iLINK input switch-
ing.)
C78: 15 • Bus full
Number of signals being transmitted over the bus exceeds
the maximum amount of signals which may be transmitted.
C78: 03 • i.LINK failure
Displayed on all units connected.
• Bus reset
Not displayed in C code because too complicated.
C78:32 • Bus reset
Displayed only for recording unit. (C code displayed only
on MD when recording from a CD to an MD.)
