CONNECTING THE VSSI-PRO
VSSI-Pro VIDEO SERIAL ATM INTERFACE
INTRODUCTION
The VSSI-Pro is designed for controlling loss and fraud at the ATM terminal. When connected between an ATM and a
recording device such as a VCR or DVR it monitors the data stream, overlaying the ATM’s transaction data onto the
video picture to get a complete picture of every transaction. The data can also be discretely sent to a remotely
located serial printer. The video input can be virtually any baseband or composite video source. The VSSI-Pro will
accept NTSC, RS-170, RS-330, CCIR, PAL, or SECAM video formats.
With its powerful Exceptions feature, the VSSI-Pro can provide on-screen alerts for whatever transactions you
program as an exception, making these exceptions easy to review on the recorded video. The programmed
exceptions can also be used to trigger an alarming devices such as VCR’s, DVR’s, Quads, Enunciators, LED’s or
other alarming devices, or a PC to record only the exception, or to the send data to another serial device such as a
serial printer. The VSSI-Pro can also be programmed to save the exceptions in buffered memory so can then be
viewed and printed at any time.
The VSSI-Pro handles all ATM communication formats worldwide with its unique auto-configuration program. It
features Auto-Poll Select Address Setup and Auto-Network Configuring, 2 programmable Alarm Outputs, and Card
Reader Contact Input.
CONNECTING THE VSSI-PRO
The most typical VSSI-Pro connection is between the ATM’s modem and the ATM’s SDLC, BISYNC, or ASSYNC
network. This is done using the AVE Triport ATM 2CH cable. The triport has male and female DB-25 connectors back-to-
back which connect to the ATM modem and the ATM network. From the side of the back-to-back DB-25 connectors
extends a cable with a DB-9 male connector which plugs into the VSSI-Pro rear port labeled “RS-232”.
The triport connection can be made while the ATM is on-line as long as you do so within 3 seconds and no one is doing
a transaction. If you take longer than this the ATM may go off-line, but if this happens, wait approximately 5 minutes and
the ATM will return on-line automatically.

Prolonged periods of time with the ATM disconnected from the network will require a
service technician to bring the ATM back on-line.
