The VSI-Pro Max will overlay the characters on any composite video source. The video input can be virtually any
baseband or composite video source. The VSI-Pro Max will accept NTSC, RS-170, RS-330, CCIR, PAL or SECAM video
formats.The Video input to the VSI-Pro Max is a standard BNC connector, terminated at 75 [ohms].
After completing the interface installation as described in the separate Installation Guide for your specific cash register,
computer, radar gun or other serial device, connect the video input source to the video input BNC on the rear of the VSI-
Pro Max. The BNC video output goes out to the video system (VCR, DVR, quad, switcher, multiplexer, or monitor). This
connection is shown in Figure 4. The video output from the VSI-Pro Max is 1[V] Peak to Peak into a 75 [ohm] load. Most
monitors or televisions with direct video inputs are terminated with a 75 ohm load. If the monitor is not terminated, the
VSI-Pro Max will still output 1[V] Peak to Peak. The VSI-Pro Max will be able to drive two terminated loads without loss
of video level.
The VSI-Pro Max uses a 9-12VDC @300 [mA] UL/CSA power supply which must be plugged into the Power input on the
VSI-Pro Max’s rear Panel utilizing a DC Coax type connector.

The input video level must be between 0.5V - 2.0V Peak to Peak. If the video is lower or not
present the VL (Video Lost) LED will illuminate signifying low or no video and the VSI-Pro Max will
have a poor or no output video signal.

Power Green Signifies power is supplied to the unit
Network LED Green This LED flashes whenever data is
sent or received on the Network Port
Register Data Red This LED flashes whenever data is
received from the cash register
Video Error Red This LED illuminates with the video
level is not present or too low
FIRMWARE UPDATE ERROR: If both the “Network LED” and
the “Register LED” are ON CONTINUOUSLY, this means the
VSI-Pro Max has no firmware installed. Please refer to Section
5.10 Page 68+ for firmware update instrustions. Firmware can be
updated via the PC Programming Software or any communica-
tions program like Hyper Terminal with the PC Programming/
Firmware Cable Part # 021-158.
Temporary PC Programming Mode
When you hold in the “Up” and “Set” buttons for
longer than 3 seconds the “Network LED” and
the “Register LED” will flash together. This sig-
nifies the unit has been enabled to RS-232 at a
baud rate of 9600 so the PC Programming soft-
ware can configure the unit. Upon exit the unit will
revert to previous settings or any new settings pro-
grammed while in this mode.
