Rear panel
⑬ ㉒ ⑭ ⑮ ⑯ ⑱ ⑰ ⑲ ⑳ ㉑
* The serial number label is located on the top panel.
NOTICE • Refer also to the instruction manuals supplied with the
external devices.
• Be careful NOT to connect the Ethernet cable from your
network device to the CU LINK terminal or DU CHAIN
terminal. This can cause damage to the connected device.
⑬
NETWORK terminal
• RJ-45
• Use for connecting to a local area network when controlling
from an external device via the Web Remote Control or IP
remote function (

⑭ CU LINK A/B terminals, DU CHAIN C/D terminals
• RJ-45
• Use for cascading multiple CUs (
➤
page 36).
You can also configure these terminals as DU/IU/INT
terminals (

page 27)
⑮ DU CHAIN A/B terminals
• RJ-45
• Use for connecting DUs/IUs/INTs. You can daisy-chain
multiple DUs/IUs/INTs as well as ring multiple DUs/IUs/
INTs using the A/B terminals
• By cascade-connecting multiple CUs, up to 300 DUs/
IUs/INTs can be connected (with a maximum of 6
INTs). (

⑱ Analog input (unbalanced) terminals: INPUT (AUX)
• RCA
⑲ Analog input (balanced) terminals: INPUT (MIC/LINE
1-2)
• Euroblock
• Pin arrangement: “+” Hot (supports phantom power)/
“–” Cold (supports phantom power)/“G” GND
• The input type can be switched between MIC and LINE
(

⑳
Analog input (balanced) terminal:
INPUT (INTERPRETATION RETURN 1-2)
• Euroblock
• Pin arrangement: “+” Hot/“–” Cold/“G” GND
• Inputs audio signals from simultaneous interpretation system
㉑ Ground screw
Since the supplied AC power cord has a three-pronged plug, as
long as your AC power wall outlet is grounded properly, the CU
will also be grounded properly.
㉒ AC Inlet (AC IN)
Connect the supplied AC power cord.
NOTICE • Do not plug in the AC power cord until all other
connections have been completed.
• Be sure that the CU is securely grounded to a single
ground point. Grounding to multiple ground points can
cause ground loops, resulting in noise generation such as
a humming noise.
