3.2 LAN communication
The NJR-TW01UHD (LAN model) and NJR-RW01UHD can be controlled from IP-NINJAR Configurator or
NJR-CTB via LAN.
Make sure not to form a loop by the NJR-TW01UHD (LAN model)/NJR-RW01UHD when connecting a LAN
cable to the NJR-TW01UHD (LAN model)/NJR-RW01UHD.
The NJR-TW01UHD (LAN model)/NJR-RW01UHD constantly send broadcast packet in order to notify status.
Broadcast storm: This problem occurs when a network system is overwhelmed by continuous broadcast
traffic or the like.
Note:
The terminal software cannot be used.

3.2.1 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-TW01UHD (LAN model)/NJR-RW01UHD to PC, HUB or the like.

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:@SDT,1,1,1,10000
“,” (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:@SDT,1
@ERR,1
■Using as HELP
If only delimiter is sent, command list as the help command is returned.
Example:
---------------- HELP (1/2) ---------------

4.4 Parameter input format
Parameter input formats are common for each setting.
If a command is input from the LAN connector of the NJR-TW01UHD (LAN model) or NJR-RW01UHD using
the IP-NINJAR Configurator, “1” (fixed) is specified to “ch” (channel) because only one NJR-TW01UHD (LAN
model) or NJR-RW01UHD can be controlled.
If a command is input from the NJR-CTB, any channel can be specified because multiple NJR-W01UHD
devices that are connected over a network switch can be controlled.
Example:
Format
@SAM, device, ch, port, mute
Parameter
device: Model
1 = NJR-TW01UHD, 2 = NJR-RW01UHD
ch: Channel
1 to 512 = Channel 1 to Channel 512
If a command is input from the IP-NINJAR Configurator, “1” is set (fixed).
port: Connector
“1” fixed
mute: Audio mute
0 = Mute OFF [Default], 1 = Mute ON
