Page 3: Preceding Procedure
Preceding Procedure There are two ways for the PET-7H24M module getting the power. One is through Ethernet by a PoE switch; the other is as usual through wiring by an external power. POE Power Supply Connect PC to the Ethernet port via the PoE switch. - Page 4 External Power Supply Connect PC and PET-7H24M to the Ethernet Switch. Connect the power supply to the switch and PET-7H24M. (The external power supply should be in the range of +12 VDC to 48 VDC) Network Settings The factory default settings for the PET-7H24M network are as follows:...

Page 7: Introduction To Acquisition And Trigger Mode
Introduction to Acquisition and Trigger Mode PET-7H24M Data Acquisition and Trigger Mode Description Two data acquisition methods and multiple trigger modes provide high-speed acquisition of input values of the AI channel. The figure below shows the corresponding effective operating frequency range for the acquisition and trigger modes. - Page 8 A/D Trigger Mode 1. Software A/D Data Acquisition Mode The A/D acquisition parameters are configured via a command from the Host PC. The continuous A/D acquisition or the acquisition of N data samples begins after the command is triggered. 2. Analog Input Analog Input Trigger is triggered when the voltage signal of the specified analog input channel is higher or lower than a certain voltage setting.
