3.1.2 RS-232C connector specification
The NJR’s RS-232C connection is supported by a 3-position terminal block.
Insert and secure the wires from the RS-232C cable into the supplied 3-position terminal block, and then
insert the terminal block into to the mating connector on the NJR-T01SDI.
AWG28 to AWG16 conductor gauge is recommended. The recommended wire strip length is 0.28 in. (7 mm).

3.2 LAN communication
The NJR-T01SDI can be accessed and controlled through LAN communication.
Connecting a control device to the NJR-T01SDI’s LAN connector enables system control and status queries
using the IP-NINJAR Configurator (configuration software for IP-NINJAR).
For operations from the IP-NINJAR Configurator, refer to the User Guide of IP-NINJAR Configurator.
The IP-NINJAR Configurator can be downloaded from
http://www.idkav.com
Note:
When using LAN communication to control the NJR-T01SDI, the terminal software cannot be used.
3.2.1 Setup LAN communication
Follow the procedure below.
(1) Connect the control device to the LAN connector of the NJR-T01SDI through a LAN cable.
(2) Start the IP-NINJAR Configurator in the control device.
(3) Send communication command from the Maintenance page of the IP-NINJAR Configurator.
You can control the NJR-T01SDI and get the status information using communication command.

3.2.2 LAN connector specification
Pin assignment of the LAN connector is as follows.
Since Auto MDI / MDI-X that distinguishes and switches straight/cross cables automatically is supported,
extra care is not necessary to connect the NJR-T01SDI to PC, HUB or the like.

3.4 Connecting LAN cable
When connecting a LAN cable to NJR-T01SDI / NJR-CTB, avoid making a network loop.
The NJR-T01SDI sends broadcast packets periodically for the purposes of internal system management.
*A broadcast storm occurs when a network is overwhelmed by continuous broadcast traffic resulting in a
network meltdown.
During installation, it is important to avoid the creation of network loops. Contact IDK if you require assistance
with network implementation.

4 Command
4.1 Summary
A command consists of “@” (“40” in hexadecimal), 3 or 4 one-byte alphabetical characters (upper and lower
cases) followed by parameters (one-byte numbers). For some commands, multiple parameter values can be
specified. Processing is executed by sending a delimiter at the end of the command.
Example: @GIV,1,1,1
“,” (a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (return+line feed, “0D” and “0A” in hex).
■If an error occurs:
An error response is returned if an undefined command or inappropriate parameter is included.
Example: @XYZ,1
@ERR,2

4.4 Parameter input format
Parameter input formats are common for each setting.
If a command is input from the RS-232C connector of NJR-T01SDI or from the LAN connector using the
IP-NINJAR Configurator, “1” (fixed) is specified to “ch” (channel) because only one NJR-T01SDI can be
controlled.
If a command is input from the NJR-CTB, any channel can be specified because multiple NJR-T01SDI
devices that are connected over a network switch can be controlled.
Example: The command for setting mute of digital audio output
