•PRODUCT OVERVIEW •
Our CN24RT &CN4RT are built in high-quality A/D and D/A converters and those converts
the Analog input-output Signal to Digital Signal and transmit the signal using UTP (CAT-5). It
contains Transmitter Box which converts the Analog Signal to Digital and Receiver Box
which convert the Digital Signal to Analog Signal.
It is available to transmit and receive the Digital Audio Signal of 40 Channel (24Channel)
simultaneously through Ethernet Network adopted CobraNet.
Also it can transmit the digital signal through UTP(CAT-5) Cable until 100 Meter in stable. In
case of over 100 Meter, you can extend the length of UTP cable easily using Ethernet Hub.
If you use our CN40RT and CN24RT in large sized sound system, you can save the cost of
analog cable and wiring. And it’s quite effective to reduce the cost in where is installed
CobraNet Network Infra.
And also, it will be helpful to solve the problems of Noise, Attenuation of Signal which come
out from Analog Cable.
Stable Function with high quality sound, No more worry about Noise
It’s solved the problem of signal diminution and noise influx problem in long distance signal
transmission and realized the clean sound environment.
Construction with only one strand of LAN using Ethernet Protocol
It’s available to transmit the signal in stable with CobraNet Program and also can be
transmitted and received Audio Signal (32Ch & 16Ch) using only one strand of UTP Cable
(CAT-5).
Built-in Hub inside and Connect easily between equipments
It’s available to connect the various equipments easily without extra Hub since our product
is built-in Hub inside and put out the link terminal on the outside.
Easy Extension using Ethernet Hub
Normally the length of CAT-5 is 100Meter, but it can be easily extended the length over
100Meter using Hub.
Economic Price
Suppose to transmit the 40Ch of signal using Analog Cables, it’s necessary lots of analog
cable and it’s not easy wiring.
Our CN40 (CN24) solve this problem completely.

•HOW TO CONNECT THE TRANSMITTER & RECEIVER (1:1) •
OUT (SEND) Part of TRANSMITTER & RECEIVER
STN40-Transmitter & STN40-Receiver are developed to transmit and receive the audio signal.
If we developed this equipment with only transmit function, it’s necessary several
equipments for transmit from Stage to Monitor Room and from Monitor Room to Stage, and
then the cost will be increased. So, we developed Digital Multi Cable STN40/24 Series with
CobraNet Program. Our STN40/24 Series is used OUT(SEND) Terminal for Signal Return and
it’s available to Receive the Signal in Transmitter.
Case of Connection for Transmitter and Receiver (1: 1 Connection)
The Group Select Switch of Option Switch should be same and No.4 Switch should be turn-
on in first equipment and turn-off in second equipment. No.5 Switch should be turn-on for
both of equipment.
Case of Connection for Transmitter and Receiver (1:N Connection)
T 1 R1
R2
The Group Select Switch of Option Switch should be same and No.4 Switch should be turn-
on in T1 and turn-off in R1, R2. No.5 Switch should be turn-off in R1 and Turn-On in R2.
In case T:R is 1:N, the value of Channel of Out (Send) Parts of R1 & R2 is exceed in 8Ch of
Receivers of T1. In this case, the first Turn-On equipment between R1 & R2 can transmit the
signal to T1. To fix this setting, Turn-On Option Switch of Equipment which to be returned to
T1, and Turn-Off the Switch of the other equipment.

Both end of cable of Transmitting and Receiving should be connected in cross.
The color of normal using cable is as above.
The recommended longest length of cable which recommended in Ethernet Protocol is 100
Meters.

SERIAL RS-232 CABLE
Please use Cable for RS-232.
No. 2,3,5 of D-SUB 9pin Male and D-SUB 9pin Female should be connected directly.
The diagram for Connection is as below.
In case there is no 9 PIN Serial Port on the PC, please buy Adaptor and install the driver.
And then the computer recognizes the Serial Port.
RECOMMENDATION OF HUB
We recommend using Switching HUB over 100MBPS.
If you use Dummy HUB instead of Switching HUB, it may be caused reducing transfer speed
and decreasing sound quality.
