Spectris PARTICLE MEASURING SYSTEMS Lasair Pro 310 - MAC Address

Chapter 4 : Connections
4-20 Lasair® Pro Aerosol Particle Counter Operations Manual
For large systems, IT personnel will dictate a network mask value, and the value may be
dierent from what is shown in the table. Make sure the network mask is set as specified
by IT. All PCs, routers and instruments on a network must use exactly the same network
mask, or communication problems will arise.
Gateway Address
The gateway address is a special address used to allow communications outside of the
local network. In the telephone analogy, it allows placing long distance calls. In many (if
not most) situations, a gateway address is not required.
The default gateway address set when restoring defaults to a Particle Measuring Systems
instrument is 10.255.0.60. Enter as aaa.bbb.ccc.ddd, where each 3-digit series is a value
of 0–255. This address should be set to whatever is required by IT.
Multicast Address
The multicast address is used by Facility Net and Pharmaceutical Net to query all
instruments attached to a local network. The valid multicast address range is defined as
224.0.0.0 to 239.255.255.255. From a practical standpoint addresses in the 224.0.X.X range
should not be used as many of them are reserved for other communications.
Particle Measuring Systems assigns a factory default multicast address of 224.100.100.1 to
all instruments. This address generally does not need to be changed, but alternates may
be entered in the form of aaa.bbb.ccc.ddd, where each 3-digit series is a value of 0–255.
The exception is when sensors are integrated into a large network. In this situation, IT may
recommend an alternative multicast address to avoid network conflicts.
Enable PMS TCP
Enables the PMS TCP/IP protocol that attaches the instrument to PMS control soware.
Disabling this function prevents the use of these applications.
MAC Address
All Ethernet devices have a MAC (Media Access Control) address. This address may be
thought of as an Ethernet serial number. It is unique for all devices. If an instrument
needs to be replaced with a dierent instrument for either calibration or service, the
service technician will duplicate the old instrument’s IP address into the new instrument.
However, the MAC address of the new instrument will be unique.
