Communication Port (Data Port)
The Data Port uses either RS232/RS485 MODBUS or MODBUS TCP/
IP (for Ethernet) protocols (see Figure 3-13 on page 9 for pinout
differences). To connect the RS485 MODBUS counter to a PC requires
an adapter cable. Please contact a Lighthouse Sales Representative for
this cable.
1. Make sure that any RS485/MODBUS instrument’s communication
cable will NOT be connected to an Ethernet TCP/IP LAN.
Connecting to these networks may result in damage to the
instrument or the LAN and will void their respective warranties.
The
Ethernet version REMOTE-4PN can, of course, be conncted
to an Ethernet LAN.
2. For information on how to use the Data Port to change the
instrument settings, please refer to “Programming with MODBUS
Protocol” on page 5-1.
