Lighthouse REMOTE 3104P, 5104P Operating Manual

Please note that only one "communication port" may be used at
one time. Attempting to simultaneously connect the instrument
to multiple interfaces, such as Ethernet AND RS485 or USB and
Ethernet or all three, will fail. The instrument must be powered
OFF before changing from one interface to another, such as from
USB to Ethernet.
Ethernet Communications
WARNING:
Connect
the Ethernet port ONLY
to an Ethernet LAN.
The Ethernet RJ45 connector provides Ethernet connectivity, over
which the 3104P or 5104P uses the MODBUS over TCP/IP
communication protocol. Communicating with either instrument on an
Ethernet LAN requires a PC or server running a MODBUS
communication package, such as LMS Express, Express RT/RT+ or
LMSNet connected to same LAN. Both must be configured to use the
same IP address range, subnet and default gateway. It is strongly
advised that the 3104P or 5104P be assigned a static IP so its address
does not change and software programs monitoring its data will not
lose contact with it due to a DHCP change. Contact the local IT or
Network Admin staff for clarification and IP assignment or Lighthouse
Technical Support for more information.
Both can be connected directly to a PC computer Ethernet port by using
a cross-over cable for testing and configuration purposes. The R3104P
or 5104P must use a ’standard’ straight-through cable to attach to an
Ethernet hub or switch.
RS-485 Communications
WARNING:
This
instrument will be
damaged and its
warranty voided if the
design of the RS-485 port
is defeated to allow daisy
chaining. The port is
designed for a star
configuration, only,
where the instrument is
the termination of a
single cable run between
it and a PC or hub.
The RS-485 port uses MODBUS ASCII for long distance multi-point
RS-485. RS-232 via USB serial communication is provided for quick
simple cable connections from a single unit to a standard PC USB
COM port.
The RS-485 MODBUS protocol is provided for industrial applications
with multiple devices on the same bus. The RS-485 port allows for
easy connection using standard CAT 5 cable commonly used for office
LANs. Connecting the counter via RS-485 requires an RS-485 hub or
switch and Cat5 cables; the LWS RS-485 converter kit may be used to
connect to a PC RS-232 COM port.
