MASTER PROTOCOL

AVE POS Networking Protocol

(VSI-ADD Protocol)

The AVE VSI-Pro Max, IF ECR Interface Cards and other POS Adapters export the POS data in formatted ASCII text via RS-232 directly. This data can be read by any DVR Com Port for recording as a separate data file appended to the Audio/Video file.

For multiple POS on one DVR you could use multiple RS-232 ports but this is cumbersome and the length of runs is limited.

The VSI-Pro Max in the Slave mode or the “Regcom” device connects directly to any of the AVE POS interfaces listed above or any RS-232 source. This buffered device takes the POS data and converts it to an RS-485 network.

The “Networker” connects only to the older VSI-Pro and supports the same RS-485 network. This network is terminated by a “Hydra” or a VSI-Pro Max in the Master mode which decodes the RS- 485 network and sends all the data to one RS-232 Com Port on the DVR.

The data from the Master device to the DVR Com Port has the following data format:

<ESC> ADDR {TEXT TO BE DISPLAYED}

Where ESC is 1BH; ADDR is one byte binary code. The valid address is 1 through 16.

The DVR will then read this protocol and decode the proper POS interface data to be associated with the respective camera.

Network Protocol

For advanced interfacing a DVR may directly control the RS-485 Regcom Network by implementing the full poll/select protocol. For more information on this contact the AVE factory.

The latest in the development of RS-485 networking is called the Vnetworker Protocol. This is an enhanced poll/select protocol that allows the remote master to program and control the remove VSI-Pro Max or VSI-Pro with Vnetworker device. Not only will this allow transaction logging but allow reading Alarm inputs, setting/reading/locking to T/D and full programming and register configuration remotely. Implementation of this protocol brings seemless POS /Cash Register / ATM interfacing to the AVE or 3rd party DVR suppliers. For more information on this contact the AVE factory.
