7.4. RS-485 CONFIGURATION OF COM2
As delivered from the factory, COM2 is configured for RS-232 communications. This port can be re-configured
for operation as a non-isolated, half-duplex RS-485 port. To configure the instrument for RS-485 communication,
please contact the factory. (Using COM2 for RS-485 communications disables the optional USB com port).
7.5. REMOTE ACCESS VIA THE ETHERNET
The calibrator can be connected to any standard 10Base-T or 100Base-T 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, but for a permanent Ethernet
connection, configure the instrument with a static IP address (Section 7.5.1.1).
