USB Commands
The USB commands available to MN4xxx
cameras are as follows:
USB_MAC_ADDRESS, USB_ISOMINEN,
USB_ISOMAXEN, USB_ISOMIN,
USB_ISOMAX, USB_PALETTE, USB_UNITS,
USB_LED, USB_NAME, USB_SERIALNUM,
USB_VIEWMODE, USB_DHCP, USB_IP_ADDRESS,
USB_NETMASK, USB_GATEWAY, USB_ALARM
This command set is sufficient setup a MN4xxx
via USB prior to placing on the IP network.
IP Addressing
IP Address Allocation
This section describes the following:
• IP address allocation and discovery for
MN4100 which doesn’t have a display
(also can be used for MN4000)
• Networks without a DHCP server will
default to an IP address which can then
be set to a static IP address
The Following methods are used for IP address
allocation:
• Auto-Find: IP discovery program returns
the IP address allocated by the DHCP
server to each AW
• Manual configuration of static IP address
• Default static IP address (192.168.1.100)
The cameras will be shipped with following IP
address allocation as default
• MN4000 ship with DHCP Enabled
(non-static address),
• MN4100 Ship with static IP address of
192.168.1.100
Ip Address Discovery (Auto-Find IP)
The units use the network DHCP server to
assign IP addresses. A discovery program is
used to return the local unit IP addresses.
For the case where there is no DHCP server
the unit will default to IP address 169.254.xx.xx,
where xx.xx is a randomly generated number.
The camera verifies this default IP address is
unique in the local network.
The auto-find will return this address.
Camera Identification (Host Name)
An auto-find is implemented using UDP
broadcast on port 46000 containing “MonitIR?”
The host name field that appears in the router
table is as follows:
• Auto-configured as Monitir_<processorU
ID>. The processorUID is a 64-bit number
• The DHCP client returns a hostname of
“MonitIR-“+(unique serial number)
• This can be used to identify any camera
in the table and will appear in the
broadcast response
• This can also be used with a unicast
address to obtain the same response
Information in the broadcast response is as
follows:
• Serial number: “M(unique serial
number)
• MAC address
• Location ID (text)
• Instrument identification
