3.4.8. CONNECTING THE COMMUNICATIONS PORTS
For RS-232 or RS-485 (option) communications through the analyzer’s two serial
interface ports, refer to Section 4.11 for information and connection instructions.
3.4.8.1. Connecting to a LAN or the Internet
For network or Internet communication with the analyzer, connect an Ethernet cable
from the analyzer’s rear panel Ethernet interface connector to an Ethernet port. See
Section 4.11.7 for configuration instructions.
Note
The T200H/M firmware supports dynamic IP addressing or DHCP. If your network
also supports DHCP, the analyzer will automatically configure its LAN connection
appropriately. If your network does not support DHCP, see Section 4.11.7.2 for
instructions on manually configuring the LAN connection.
3.4.8.2. Connecting to a Personal Computer (PC)
If the USB port is configured for direct communication between the analyzer and a
desktop or a laptop PC, connect a USB cable between the analyzer and the PC or laptop
USB ports, and follow the set-up instructions in Section 4.11.8. (RS-485 communication
is not available with the USB com port option).
