Teledyne API - Model T200H/T200M Operation Manual Operating Instructions
169
There are two methods to activate control inputs. The internal +5V available from the
“+” pin is the most convenient method (see Figure 6-18). However, to ensure that these
inputs are truly isolated, a separate, external 5 VDC power supply should be used (see
Figure 6-19).

4.15.2. REMOTE OPERATION
4.15.2.1. Terminal Operating Modes
The Model T200H/M can be remotely configured, calibrated or queried for stored data
through the serial ports. As terminals and computers use different communication
schemes, the analyzer supports two communicate modes specifically designed to
interface with these two types of devices.
Computer mode is used when the analyzer is connected to a computer with a
dedicated interface program such as APICOM. More information regarding
APICOM can be found in later in this section or on the Teledyne API website at
http://www.teledyne-api.com/software/apicom/.
Interactive mode is used with a terminal emulation programs such as
HyperTerminal or a “dumb” computer terminal. The commands that are used to
operate the analyzer in this mode are listed in Table 6-31 and in Appendix A-6.
