9. Quick Start Guide
Please follow the steps:
1. Install IRT_VMS if the thermal camera is with other networking equipments, and
IRT_TAS_AT can be installed on a single thermal camera for temperature
measurement and analysis. The software may have version updates. Please refer to
the actual version. It is recommended that the computer configuration for installing
the software meet the following conditions: i5-9500T and above CPU, 8G and above
memory, 64-bit win10 system, and supporting Gigabit network.
2. Connect the thermal camera, power supply and computer.
3. Set the computer configurations according to the software instructions for
IRT_VMS_User Manual or IRT_TAS_AT_User Manual.
4. Double-click the client icon, enter the correct user name and password, and click
login to start the client.
5. Select the IP on the client homepage, and add the module number you want to
preview to the PC preview interface. If the thermal camera is successfully connected,
you can start imaging and monitoring with the thermal camera.
6. The 232 transmission between the computer and the thermal camera can be
realized through the RS232 interface on the cable.
7. The 485 transmission between the thermal camera and the PT can be realized
through the RS485 interface on the cable to contron the PT.
8. The ALARMIN interface on the cable can be used to manually input signals to
trigger the alarm.

9. The I/O alarm output of the thermal camera can be realized through the
ALARMOUT interface on the cable. Non-alarm information remains high, and
becomes low when there is alarm information. After the alarm disappears, it will
continue to be maintained for 30 seconds and then return to high level.
