Real-time images cannot be viewed. This is a snapshot camera. Regarding the serial terminal being used, if the data logger is a PakBus CR510 or CR10X, then the interface is not RS-232; the interface is CS I/O, which is a 5 V system. This interface is also addressable, meaning that more than one device can use the terminal at the same time. If a CR1000 or CR3000 is used, both 9-pin connectors and all four COM terminals can be used to acquire images.
