Single Instrument Connected to a PC
•
For connection to a PC RS232 port, the instrument can be a Laureate meter with an
RS232 interface board (ordering option 1) and Laureate RS232 interface cable CBL01.
The instrument can also be a Laureate LT transmitter whose data output has been
jumpered for RS232 and use RS232 interface cable CBL04. The PC must be set to the
appropriate COM port and instrument address (the default address is 1).
•
For connection to a PC USB port, the instrument can be a Laureate meter with a USB
interface board (ordering option 5) and use USB interface cable CBL05. The PC must
be set to the USB selected COM port and instrument address (the default address is 1).
•
For connection to a PC Ethernet port, the instrument can be a Laureate meter with
an Ethernet interface board (ordering option 7) or a Laureate LTE transmitter. A stan-
dard Ethernet cable with RJ45 connectors can then be used to connect the Ethernet
jack of the meter to the Ethernet jack of the PC. If the PC is turned after the instrument
by 30 seconds or more, the Ethernet Node in the instrument will act as a DHCP server
and establish communications with no need to use Laurel’s Node Manager Software.
Multiple Instruments Connected to a PC
•
For connection to a PC USB port, a first Laureate meter with an RS485 interface
board (ordering option 2) can be connected to the PC using Laurel’s CBL06 USB-to-
RS485 Adapter Cable, which supports half-duplex RS485 communications. An addi-
tional 30 Laureate meters with an RS485 interface board (ordering option 2) can then
be daisy chained to the first meter using Laurel’s CBL03 RS485 Data Cable for Meters.
Daisy chaining of meters without a hub uses two RJ11 jacks wired in parallel on each
RS485 interface board.
