Teledyne API – Model T700 Dynamic Dilution Calibrator Communications Setup and Operation
181
5.3. RS-485 (OPTION)
The COM2 port of the instrument’s rear panel is set up for RS-232 communication but
can be reconfigured for RS-485 communication. Contact Customer Service. If this
option was elected at the time of purchase, the rear panel was preconfigured at the
factory. Choosing this option disallows use of the USB port.
5.4. REMOTE ACCESS VIA THE ETHERNET
Via the Ethernet interface, the calibrator can be connected to any standard 10BaseT or
100BaseT Ethernet network via low-cost network hubs, switches or routers. The
interface operates as a standard TCP/IP device on port 3000. This allows a remote
computer to connect through the Internet to the calibrator using APICOM, terminal
emulators or other programs.
Under the SETUP>MORE>COMM menu the INET submenu is used to manage and
configure the Ethernet interface with your LAN or Internet Server(s). The calibrator is
shipped with DHCP enabled by default. This allows the instrument to be connected to a
network or router with a DHCP server (Section 5.4.1), but for a permanent Ethernet
connection, configure the instrument with a static IP a
ddress (Section 5.4.1.1).
The Ethernet LEDs located on the connector
indicate the Ethernet connection status.

5.4.1. CONFIGURING THE ETHERNET INTERFACE USING DHCP
The Ethernet feature for your T700 uses Dynamic Host Configuration Protocol (DHCP)
to configure its interface with your LAN automatically. This requires your network
servers also be running DHCP. The calibrator will do this the first time you turn the
instrument on after it has been physically connected to your network. Once the
instrument is connected and turned on, it will appear as an active device on your
network without any extra set up steps or lengthy procedures.
Note
Check the INET settings the first time you power up your calibrator after it has
been physically connected to the LAN/Internet to ensure that the DHCP has
successfully downloaded the appropriate information from your network
server(s).
