POS Configuration
When the POS device transmits ASCII data, the NVR can record without any interface devices. (ex.,
AVE device – VSSI Pro) However if the POS device is sending data other than ASCII protocol, it is
recommended to use the AVE interface device.
For example, the AVE’s VSSI –PRO device is point to point, (ASCII standard protocol) but if the user
would like to use multiple POS with the NVR, it is needed to use AVE’s VSI –PRO Max (VSI-ADD)
interface. Further details, please refer to the VSI-Pro Max Networking as below and AVE’s manual.
For connection of POS/ATM device to the NVR, the user must supply a USB to RS232 converter cable
as like the image below. Depending on the USB to RS232 converter cable manufacturers, some
converters may not be compatible with the NVR due to their difference in converter chip specification.
It is strongly recommended to test the compatibility (connection) of USB to RS-232 converter with the
NVR.
