Master Protocol (Vsi-Add) - AVE VSI-Pro Max Operation Manual

APPENDIX M 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.
