The calibrator is equipped with 12 opto-isolated, digital control outputs, which may be
used to interface with devices that accept logic-level digital inputs, such as programmable
logic controllers (PLCs), data loggers, or digital relays/valve drivers.
These outputs are accessed via a 14-pin connector on the calibrator's communications and
output panel and can be activated in any of three places in the Setup>Sequence menu (see
Section 4.2.7.4 for instructions on assigning the control outputs to specific calibration
sequences or as a default method when sequences are not running).

The T-Series instruments are equipped with connectors for remote communications
interfaces.
In addition to using the appropriate cables, each type of communication method must be
configured using the Setup>Comm menu, which is presented later in this manual
(Section 3.3.11).
E
THERNET
For network or Internet communication with the instrument, connect an Ethernet cable
from Ethernet interface connector to an Ethernet port.
The calibrator firmware supports dynamic IP addressing or DHCP for remote operation via
an Ethernet connection. Although the calibrator is shipped with DHCP enabled by default,
it should be manually assigned a static IP address (Setup>Comm>Network Settings
menu, Section 3.3.11.4).

Most PLCs have internal provisions for limiting the current the
input will draw. When connecting to a unit that does not have
this feature, external resistors must be used to limit the current
through the individual transistor outputs to ≤50mA (120 Ω for
5V supply).
