Appendix A: Utility Mode 113
D-Command Test Pages
The Test pages let you test various mechanical and electronic
components of the unit.
To display the Test Setup page:
„
From the Utility Setup page, press the Soft Key (Main Unit)
or the encoder Select switch (Fader Module) that corresponds
to “Test.”
The Test Setup page has five top level test modes:
• Ethernet: Ethernet Test Page
• LED: Switch and LED Test Pages
• Display: Display Test Page
• Fader: Fader Test Page
• Rotary: Rotary Encoder Test Page
To enter a test mode on the Test Setup page:
„
Press the Soft Key (Main Unit) or the encoder Select switch
(Fader Module) that corresponds to the test mode name.
To exit the Test Setup page:
„
Press the Soft Key (Main Unit) or encoder Select switch
(Fader Module) that corresponds to “Escape.”
Ethernet Test Page
There are three test levels for Ethernet communication on
D-Command: Internal, Mendec, and External. These tests can
assist Digidesign Technical Support should you ever experi-
ence difficulty with Ethernet communication between
D-Command and Pro Tools.
Each test sends data packets through that unit’s Ethernet sys-
tem. The Transmit (Xmit) and Receive (Recv) values for each
test show the number of packets sent and received in the test,
and the “Error” and “Retry” fields show percentage error in
the transmission and receiving process. An error rate of 1 per-
cent or less generally indicates acceptable performance. (In
normal operation, errors are retried and no data loss occurs.)
To display the Ethernet Test page:
1
Put the unit you want to test into Utility mode. Fader Mod-
ules must be put into Utility mode independently. (See “Enter-
ing Utility Mode on a Fader Module” on page 111.)
2
From the Test Setup page, press the Soft Key (Main Unit) or
encoder Select switch (Fader Module) that corresponds to
“Ethrnt.”
To exit the Ethernet Test page:
„
Press the Soft Key (Main Unit) or encoder Select switch
(Fader Module) that corresponds to “Escape.”
Internal
The Internal test verifies the first stage of Ethernet communi-
cation by sending data packets through the unit’s Ethernet
link chip.
To perform the Internal Ethernet test:
1
From the Ethernet Test page, press the Soft Key (Main Unit)
or the encoder Select switch (Fader Module) that corresponds
to “Clear” to clear any values in the unit’s test data page.
2
Press the Soft Key (Main Unit) or the encoder Select switch
(Fader Module) that corresponds to “Intrnl.”
To exit the Internal Ethernet test:
„
Press the flashing Soft Key (Main Unit) or encoder Select
switch (Fader Module).
Mendec
The Mendec (Manchester Encoder/Decoder) test verifies the
second stage of Ethernet communication by sending data
packets through the unit’s Ethernet encoder and decoder.
To perform the Mendec Ethernet test:
1
From the Ethernet Test page, press the Soft Key (Main Unit)
or the encoder Select switch (Fader Module) that corresponds
to “Clear” to clear any values in the unit’s test data page.
2
Press the Soft Key (Main Unit) or the encoder Select switch
(Fader Module) that corresponds to “Mendec.”
To exit the Mendec Ethernet test:
„
Press the flashing Soft Key (Main Unit) or encoder Select
switch (Fader Module).
External
The External test verifies the third stage of Ethernet commu-
nication by sending data packets out of the unit’s external
Ethernet port and back into the unit using the Ethernet loop-
back connector (provided with the D-Command Main Unit).
To perform the External Ethernet test:
1
If Pro Tools is running, quit Pro Tools.
2
Disconnect the unit from the Ethernet network.
3
Plug the Ethernet Loopback connector into the unit’s Ether-
net port.
4
From the Ethernet Test page, press the Soft Key (Main Unit)
or the encoder Select switch (Fader Module) that corresponds
to “Clear” to clear any values in the unit’s test data page.
5
Press the Soft Key (Main Unit) or the encoder Select switch
(Fader Module) that corresponds to “Extrnl.”
