Operation
Model 1120 with an asterisk, and the user has to know what thermocouple type the asterisk
represents. In the Model 1140A, any thermocouple type can be designated as the “asterisk”
thermocouple type.
The Model 1120 Remote Emulation mode will work over all interfaces offered for the
Model 1140A, although this mode was created for customers who were using Model 1120’s and
desired to upgrade to the Model 1140A without rewriting remote code for their calibration and
production systems. Nearly all of these customers were using the GPIB interface.
When the Model 1120 Remote Emulation option is installed and enabled, standby mode is
unavailable.
Changing the active interface
To change the active interface from the REMOTE menu, highlight ACTIVE INTERFACE, press
ENTER, highlight the desired interface to activate, and again press ENTER.
USB Setup
No setup is needed in the Model 1140A to use the USB interface. If using LabVIEW, the
Model 1140A is a USB Test & Measurement Class (USBTMC) device.
GPIB Setup
The only setup necessary for GPIB use is setting the address. To set the address of the GPIB
interface, whether it is active or not, highlight GPIB SETUP and press ENTER. Then, using the
encoder or the arrow keys, enter a valid address (0 to 30) and again press ENTER.
Ethernet Setup
DHCP Enabled
Enable DHCP (Dynamic Host Configuration Protocol) to allow adding the Model 1140A to a
network with little interaction required. To enable it, highlight ETHERNET SETUP and press
ENTER. Then using the arrow keys or the encoder, select ENABLE and press ENTER. When DHCP
is enabled, the IP ADDRESS, NETMASK, GATEWAY, and NAMESERVER are set by a DHCP server
on the network.
When DHCP is enabled, the user simply may give the Model 1140A a HOST NAME, which can be
blank, and the TELNET PORT number.
Host Name
The HOST NAME is the unique name by which the device is known on the network. To create or
change it, highlight HOST NAME and press ENTER. Create any name from 0 to 15 characters
using the keypad, arrow keys, and the ENCODER. Names can include numbers and letters. No
blanks or symbols are allowed. To remove a character, place the cursor under the character to be
removed and press the +/− key. When finished, press ENTER.
Telnet Port
The default setting for the TELNET PORT (Telecommunication Network) is 23. Valid port
numbers are any between 0 and 65535. To change it, highlight TELNET PORT and press ENTER.
Although the arrow keys and the ENCODER can be used to change the port, use the keypad to
4-19
