3-5
STOP <1/2> - Set the serial port stop bits
SUBNET <ip address> - Set IP subnet mask for this unit
TRAN - Place this unit's serial port in transparent mode
VER - Print the software version information for this unit
VOCODER <number> - Select the voice compression method (1-5)
WHAT - Print a description of this unit's settings
BOOST <0/1> - Select either no boost (0) or +20 dB boost (1) on audio input
RXDELAY <0-9999> - Set the received audio delay in milliseconds
TXDELAY <0-9999> - Set the transmitted audio delay in milliseconds
VSENSE <0/1/2> - set the VOX/VMR sensitivity to low (0), medium (1), or high (2)
3.3.3
Setting Unit IP Address
The first thing you should do is to set the IP address of the unit. The NXU-2A comes from the
factory with a default IP address set to 192.168.1.200. Set the address by typing:
MYIP <IP address>
Where <IP address> is the IP address of the unit in dotted quad notation. All configuration
commands are entered by a carriage return. In this example, if your desired IP address is
192.168.1.1 you would type MYIP 192.168.1.1 and press ENTER
3.3.4
Setting Unit Subnet Mask and Gateway Address
Now set your subnet mask using the SUBNET command. If you are using a gateway, set the
gateway address (the address of your router) using the GATEIP command. If on a LAN with no
gateway, leave the gateway address set at the default address 0.0.0.0.
3.3.5
Using DHCP to Assign IP Parameters
If you have a DHCP server on your network, you may configure the NXU-2A to obtain its IP
address, subnet mask, and gateway address via DHCP. Setting the NXU-2A IP address to
0.0.0.0 will cause it to attempt to contact a DHCP server on power-up. NOTE: Using DHCP is
not recommended for NXU-2A Server units since the IP address assigned by the DHCP server
is not generally known and is subject to change. If DHCP is to be used, it should only be used
on client NXU-2A units.
3.3.6
Setting VoIP Port (Optional)
The port used by the NXU-2A for receiving audio from the network which defaults to 1221.
Under normal circumstances, this should not be changed. The default value may be changed, if
necessary, by using the PORT command. Type PORT <port number> and press ENTER to
select a new VoIP port. The port number must range from 1 to 65535 and be different from the
command port.
