Advanced Management Functions
The 516TX-A offers several management functions that can be 
easily confi gured using the COM Port (DB 9 Connector located 
on the right side of the switch).
IGMP Snooping - Internet Group Management Protocol is 
a feature that allows the 516TX-A switch to forward and fi lter 
multicast traffi c intelligently. 
VLAN - Virtual Local Area Network allows segmentation of the 
switch in order to create two or more separate local area network 
domains. 
QoS - Quality of Service provides prioritization of network traffi c
in order to provide better network service. The primary goal of 
QoS is to improve the latency of prioritized Ethernet packets 
required for ring management, real-time and other interactive 
applications. 
Trunking - Trunking (aggregation) enables multiple physical 
ports to be linked together and function as one uplink to another 
N-TRON trunking capable switch confi gured in the same manner, 
thereby increasing the bandwidth between switches. This 
confi guration can provide increased bandwidth and redundancy to 
applications requiring high levels of fault tolerant operation.
Port Mirroring - This 516TX-A function allows the traffi c on 
one port to be duplicated and sent to a designated mirror port. 
Port mirroring can be used to monitor Ethernet traffi c on the 
designated source port using the assigned mirror port.
N-View OPC Switch Monitoring (With -A or -N Option Only)
The N-TRON N-View OLE for Process Control (OPC) server 
software can be combined with popular HMI software packages 
to add network traffi c monitoring, trending and alarming to 
any application using N-TRON switches confi gured with the 
N-View option. N-TRON's N-View OPC Server collects 41 
different traffi c variables per port and 5 system level variables 
per switch. This information can provide a complete overview 
of the network load, service quality, and packet traffi c. OPC 
client software can use N-View OPC Server data to resolve 
network problems quickly and improve system reliability.
Industrial Packaging and Specifi cations
The N-TRON 516TX is designed to operate in industrial 
environments. It is housed in a rugged steel enclosure 
that can be DIN-RAIL or panel mounted, and an optional 
rackmount kit is also available. The 516TX comes standard with 
extended temperature rating, extended shock and vibration specs, 
redundant power inputs, and a high MTBF (greater than 2M hours).
Ease of Use
The N-TRON
516TX requires no setup unless the advanced
port functions are utilized. The sixteen 10/100BaseTX ports 
are auto sensing and auto configuring. Each copper port is 
automatically negotiated for maximum speed and performance 
by default. Bi-color LED's are provided to display the link 
status, link speed and activity of each port as well as power 
on/off status.
Performance
The N-TRON 516TX uses "state of the art" IEEE 
8 0 2 . 3 F a s t E t h e r n e t 1 0 / 1 0 0 B a s e T X s w i t c h i n g 
technology. This technology eliminates network collisions 
and increases network determinism. Up to 4,000 MAC 
addresses are supported enabling sophisticated and complex 
network architectures. A high speed processor and backplane 
allows wire speed capability on all ports simultaneously.
