Electro-Voice | CM-1 CobraNet Module
CM-1 CobraNet Module
▪ Connect N8000 to a CobraNet digital audio network
▪ Two 100BASE-TX Ethernet interfaces for system
redundancy
▪ 48 kHz sample rate and 16-, 20-, or 24-bit wordlength
▪ EN 54-16: 2008
CobraNet is a network technology for multi-channel
transmission of digital audio data. The CM-1 is a
compact interface module for connection to a
CobraNet network allowing the simultaneous
transmission of up to 32 digital audio input signals and
32 digital audio output signals.
Additional CM-1 features:
• 100BASE-TX Ethernet Interface - 100Mbit/s fullduplex Ethernet Interface; IEEE 802.3u compatible.
• Secondary 100BASE-TX Ethernet Interface - Second
Ethernet Interface for the connection of a redundant
network to establish fault-tolerant systems.
• Four serial output ports - Internal audio output
interface for the transmission of 32 digital audio
channels with 48 kHz sample rate and 16, 20 or 24-bit
word length.
• Four serial input ports – Internal audio input interface
for receiving 32 digital audio channels with 48 kHz
sample rate and 16, 20 or 24-bit word length.
• Status LEDs - Link, Activity, Fault and CobraNet
Conductor status indication via Ethernet connectors.

Turn off the power of the unit and pull the mains plug
Remove the cover plate (N8000/P 64: 6 screws on the
sides, 3 screws on top, 4 screws on the rear; DPM
8016: 10 screws on top)
Remove the blind on the rear panel (2 screws)
Install the CM-1 module (see picture); first, secure it
with 2 screws on the rear panel (A), then with 2
screws on the bolt (B), tighten the screws
Make the following cable connections: N8000/P 64: J1 on CM-1 module with CN28 on main board 80500
(65 mm flat wire cable) (C) - J3 on CM-1 module with
CN5 on DSP-Board 80496 (190 mm flat wire cable)
(D). DPM 8016: - J1 on CM-1 module with DN12 on
main board 80506 (65 mm flat wire cable) (C) - J3 on
CM-1 module with CN11 on main board 80506 (190
mm flat wire cable) (D)
Re-install the cover plate
Plug in the mains cord and turn the unit’s power on
