3.4 Connecting LAN cable
When connecting a LAN cable to NJR-T01UHD / NJR-R01UHD / NJR-CTB, avoid making a network loop.
The NJR-T01UHD and NJR-R01UHD send 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: @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
■HELP
Command list is returned as HELP command by sending only delimiter without specifying any command.
Example:
---------------- HELP (1/2) ---------------

4.4 Parameter input format
Parameter input formats are common for each setting.
If a command is input from the RS-232C port of NJR-T01UHD / NJR-R01UHD or from the LAN port using the
IP-NINJAR Configurator (Software for setting IP-NINJAR), “1” (fixed). is specified to “ch” (channel) because
only one NJR-T01UHD / NJR-R01UHD can be controlled.
If a command is input from the NJR-CTB, any channel can be specified because multiple NJR-T01UHD /
NJR-R01UHD devices that are connected over a network switch can be controlled.
Example: The command for setting mute of digital audio output
Format @SAM, device, ch, port, mute
Parameter device: Model type
1 = NJR-T01UHD, 2 = NJR-R01UHD
ch: channel
1 to 512 = Channel1 to Channel512
If a command is input from the RS-232C port of NJR-T01UHD/NJR-R01UHD or
from IP-NINJAR Configurator (Software for setting IP-NINJAR) through LAN, the
value is “1” (fixed).
