1. Reset key [RESET]
Pressing this key reactivates this unit.
2. LNK/ACT indicator [LNK/ACT] (Green)
Lights when connected to a network, and flashes
while transmitting or receiving data.
3. Status indicator [STATUS] (Red)
Continuously lights while data is written to an
internal storage medium (FlashMemory).
Flashes if there is a failure.
4. Power indicator [POWER] (Green)
Lights when power is supplied to the unit.
5. MAC address
This is the address* 1 used by the unit. Since the
relationship of each exchange location to its MAC
address is established when setting the network
attributes, keep track of this relationship for later
use.
* 1 The inherent address assigned to each network
component, expressed in 12-digit hexadecimal
notation.
6. Signal indicator [SIGNAL] (Green)
Lights when audio is input.
7. Peak indicator [PEAK] (Red)
Lights when over-input is applied to the audio input.
8. Cord clamp
Pass the power cord through this clamp to ensure
that the plug does not pull out when the unit is
mounted to a wall. (Refer to p. 11.)
9. AC inlet
Connect the supplied power cord.
Note
If there is a danger of lightning strikes, insert an
appropriate surge arrester into the power line.
10. Audio output terminal [AUDIO OUTPUT]
This terminal connects to a recording device, etc.
(Refer to p. 14.)
Max. 0 dB* 2 , 600 Ω or less, balanced
11. Contact input terminals [CNT IN]
No-voltage make contact inputs.
Short-circuit current: under 5 mA, Open-circuit
voltage: 24 V
Connect using a removable terminal plug.
(Refer to p. 14.)
12. Contact output terminals [CNT OUT]
Relay contact outputs.
Withstand voltage: 24 V DC, Control current: 2 –
500 mA
Connect using a removable terminal plug.
(Refer to p. 14.)
13. Network connection terminal [10/100M]
Connects to a 10BASE-T- or 100BASE-TX-
compatible network. (Ethernet RJ-45 jack)
14. Functional earth terminal [SIGNAL GND]
Ground this terminal.
Note: This terminal is not for protective earth.
15. Input volume control [INPUT VOLUME]
Adjusts the input signal level. Use this volume
control to adjust the signal level to below the point
where the Peak Signal Indicator begins to light.
16. Audio input terminal [AUDIO INPUT]
Connect the microphone or other sound source
equipment to this terminal.
(Refer to p. 14.)
Max. 0 dB* 2 , 2 kΩ or more, balanced
17. Time sync input terminal [TIME SYNC]
Connect the Program Timer, etc. to this terminal.
Use the removable terminal plug for connection
of this terminal.
(Refer to p. 14.)
* 2 0 dB = 1 V
