Cisco Codec Pro G2 CS-CPRO-NR-K9 – No-Radio Standalone Codec

Product Overview

Facilities that prohibit wireless radios in meeting spaces specify the Cisco Codec Pro G2 as CS-CPRO-NR-K9. The non-radio version omits the Wi-Fi 6 / 6E radio while keeping the full wired feature set of the second-generation Pro codec: five HDMI 2.0 inputs, three HDMI 2.0 outputs, four phantom-powered Euroblock microphone inputs, a multi-gigabit IP peripheral port and eight IEEE 802.3bt PoE ports sharing a 120 W budget. That makes it the practical choice for SCIFs, defence sites, RF-restricted clinical areas and any organisation whose security policy bars unmanaged radios from a room system. Codec Pro G2 is a current product with no Cisco end-of-sale bulletin.

Product Description

Removing the radio changes how the room is cabled rather than what it can do. Every peripheral on a CS-CPRO-NR-K9 build reaches the codec over copper: eight PoE / PoE+ / PoE++ ports carry digital microphones, Room Navigators and IP cameras within a 120 W budget, a multi-gigabit port up to 10 Gb carries video over IP, and the RJ-45 LAN port handles call signalling. For a secure facility this is an advantage during accreditation, because the room's entire communication path is physically inspectable.

What a no-radio unit gives up is the wireless convenience layer. Wireless content sharing that depends on the radio is not available on a non-radio codec, so a room design should plan wired presentation paths: five HDMI 2.0 inputs at up to 3840 x 2160 at 30 fps with 5120 x 2160 at 30 fps on HDMI 1 to 4, HDCP 2.3 on HDMI 4, a USB-C DisplayPort Alt-mode input to 5120 x 2160 at 30 fps, and USB-C passthrough at 5 Gbps with 15 W power delivery that hands a guest laptop the room camera, microphones and speakers over one cable.

Audio integration is unchanged. Four 48V phantom-powered 3.5 mm Euroblock inputs rated to a maximum 18 dBu take ceiling arrays or gooseneck microphones, two balanced line-level Euroblock outputs at up to 8 dBu feed an external amplifier or DSP, and AES67 runs in and out across the PoE ports at eight streams of eight channels. Rooms with existing conference audio systems can therefore keep their DSP and use the codec as the conferencing endpoint only.

Display output is three HDMI 2.0 ports with CEC 2.0, HDMI 1 reaching 7680 x 4320 at 30 fps and 3840 x 2160 at 60 fps with HDCP 2.3. The 16.9 x 2.6 x 9.9 in., 6.2 lb chassis mounts on a wall, on rack ears or free-standing, and a 4-pin Euroblock GPIO port supplies 12V at up to 0.7 A for door interlocks, screen lifts and partition sensors. Cisco requires RoomOS 26.5 or later and lists registration to Webex, Microsoft Teams Rooms, Zoom for Cisco Rooms, Cisco Expressway and Cisco Unified CM v15 SU4 or later. See large room solutions and video conference systems for surrounding room components. Cisco has not published a standalone Codec Pro G2 data sheet: every specification quoted here is drawn from the Cisco Room Kit Pro G2 data sheet, which is where Cisco documents the codec.

Key Features

• No-radio hardware for restricted sites — The Wi-Fi radio is absent on this version, which is what secure facilities, SCIFs and RF-restricted clinical or defence spaces require from a room codec.
• Eight PoE++ ports with a 120 W budget — The codec powers and connects up to eight IEEE 802.3bt devices such as digital microphones, Room Navigators and IP cameras directly, removing most local power supplies from the rack.
• 10 Gb IP peripheral port — A dedicated multi-gigabit port carries video over IP, letting cameras and peripherals reach the codec over structured cabling instead of long HDMI runs.
• Five HDMI 2.0 inputs with 5K and HDCP 2.3 — HDMI 1 to 4 accept 5120 x 2160 at 30 fps and HDMI 4 handles HDCP 2.3, so protected sources and ultra-wide laptops connect without an external scaler.
• 8K-capable HDMI output — HDMI 1 supports 7680 x 4320 at 30 fps as well as 4K60, so the codec can drive very high resolution displays in premium rooms.
• GPIO Euroblock control port — A 4-pin GPIO providing 12V at up to 0.7 A with an open-drain output sinking up to 1 A lets the codec trigger or be triggered by room control, partition sensors and screen lifts.
• USB-C passthrough with 15 W power delivery — One USB-C cable gives a guest laptop the room camera, microphones and speakers plus charging, covering BYOD without a separate switching appliance.
• AES67 in and out over the PoE ports — Eight streams of eight channels inbound and up to four outbound digital streams let the codec join an existing AES67 audio network.
• Nine-camera independent control — Cisco states up to nine cameras can be controlled independently, which covers divisible rooms and lecture capture from a single codec.

Typical Applications

• Government space — a codec with no wireless radio meets facility policies that bar unmanaged RF emitters from meeting rooms.
• Boardroom — a wired executive room keeps every peripheral path physically inspectable while still driving three displays.
• Large conference room — five HDMI inputs and up to five video-over-IP streams support multi-camera front-of-room builds on copper only.
• Training room — PoE++ digital microphones and independent control of up to nine cameras cover instructional spaces without wireless links.
• Commercial meeting space — organisations with RF-restricted floors can standardise on the same codec used elsewhere in the estate.

Technical Specifications

Frequently Asked Questions

What exactly is removed on the non-radio version?

Cisco states that the Wi-Fi 802.11a/b/g/n/ac/ax (Wi-Fi 6 / 6E) radio is not present on non-radio versions. Wired connectivity is unchanged, so the LAN port, the multi-gigabit IP peripheral port and the eight PoE / PoE+ / PoE++ ports all operate normally.

How many displays can this codec drive?

Three HDMI 2.0 outputs with CEC 2.0. HDMI 1 reaches 7680 x 4320 at 30 fps and 3840 x 2160 at 60 fps with HDCP 2.3, HDMI 2 reaches 3840 x 2160 at 60 fps with HDCP 2.3, and HDMI 3 reaches 3840 x 2160 at 60 fps.

What microphone options does it support?

Four 48V phantom-powered 3.5 mm Euroblock analog inputs rated to a maximum 18 dBu, embedded audio on five HDMI inputs, one USB-C and one USB-A audio input, and eight PoE / PoE+ / PoE++ Ethernet ports carrying digital microphones or AES67 at eight streams of eight channels.

Does it need separate power supplies for room peripherals?

In most builds, no. Eight IEEE 802.3bt PoE / PoE+ / PoE++ ports share a 120 W total budget for digital microphones, Room Navigators and IP cameras, and a separate multi-gigabit port up to 10 Gb serves IP peripherals.

Can it integrate with a third-party room control system?

The codec provides a 4-pin 3.5 mm Euroblock GPIO port supplying 12V +/-5% at up to 0.7 A with an open-drain output sinking up to 1 A, which is the documented hardware control interface. Cisco does not publish a third-party control-system driver list for this codec, so confirm driver availability with your control-system vendor.

How is it mounted, and what are the dimensions?

Cisco lists wall, rack-ear and free-standing mounting for a chassis measuring 16.9 in. (43.4 cm) wide, 2.6 in. (6.6 cm) high and 9.9 in. (25.2 cm) deep, weighing 6.2 lb (2.8 kg). Cisco publishes no rack-unit figure for the G2 chassis.

What cameras does Cisco document with Codec Pro G2?

Cisco documents the Cisco Quad Camera, the Cisco Room Vision PTZ Camera and the Cisco 4K Desk Camera over USB-A, and states that up to nine cameras can be controlled independently.
