Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Master Connection Modes
The mode of communication used for connection to the Master is specified via the
SET
CONNECTION
Telnet command
(see page 101).
The connection mode setting options are AUTO, TCP URL, UDP URL, or NDP (default) as described below.
AUTO
– This mode utilizes TCP communication. It looks for a matching System Number and attempts to
come online with the first Master it sees with that System Number.
TCP URL
– TCP; the Master is specified via URL.
UDP URL
– UDP; the Master is specified via URL.
NDP
– UDP; this mode utilizes the NDP binding process to assign the
DXLink Fiber
unit (the physical
device) to a Master (or Virtual Master) via NetLinx Studio. Once bound, communications are conducted
via UDP.
Note:
In URL modes, the Master can use either an IP address or a DNS name.
Guidelines
UDP mode
is recommended for the following types of installations:
Small-to-medium residential and corporate installations on a single subnet
Segmented control network installations (control network is a separate switching domain and subnet from
other network equipment)
Installations with the total of NetLinx / ICSNET devices on a single Master exceeding 128
TCP mode
is recommended for installations where (a) the switching domain of the network is subject to
“
bursty
”
traffic
or heavy streaming activity (>20 Mbps consumption by streaming)
and
where (b) the total number of NetLinx / ICSNET
devices on a single Master is less than 128.
TCP vs. UDP
