The LTC 5104 Series and LTC 5108 Series are automatic
sequential video switchers. The LTC 5104 Series have 4-
camera inputs and 1-monitor output; the LTC 5108 Series
have 8-camera inputs and 2-monitor outputs. All models
are microprocessor-based.

Functions
The auto-terminating BNC connectors eliminate the need
for the user to select a 75 Ohm terminated video input or
high impedance, un-terminated video input with looping
video output. The switcher sets itself correctly for either
situation. The looping video output allows another piece
of equipment to be connected to the same video line.

Features include a 16-character camera title, nonvolatile
memory back-up, on-screen status line, on-screen
configuration menus in English, French, German, and
Spanish (11 for the LTC 5104 Series and 12 for the
LTC 5108 Series), and a SMART Setup. The status line
displays the present camera number, the operation status,
and camera title. There are five operation status
notations:

•

S – skipped camera displayed

•

RUN – sequence running

•

MA – monitor armed

•

ALARM – alarm closure call-up

•

HOLD – camera held.

The Configuration Menus include Dwell Adjust, Operating
Mode (LTC 5108 Series only), Alarm Reset Mode, Alarm
Capture, Capture Time, Alarm Dwell Time, Alarm Contacts
Option, Status Line, Brightness and Background of titles,
Display Position, System Reset, and Camera Title. The
VideoSearch™ feature detects any camera inputs without
video and sets them to be skipped.
These versatile switchers provide individually or globally
adjustable camera dwell times from 1 to 64 seconds.
Automatic camera call-up can be activated by motion
detectors or remote alarm closures. Alarm contact can be
selected either normally-open or normally-closed. Alarms
override normal operating mode to home on alerted
camera. Vertical interval switching gives roll-free viewing.
An alarm output is provided to activate a VCR to record
alarms. The minimum time that an alarm will be held once
triggered (unless cleared or the alarm input is disabled)
can be set to 1 to 63 seconds. Sequencing through
multiple alarms can be set to occur at a dwell of 1 to 64
seconds.
Two modes of operation can be selected for the LTC 5108
Series switchers. The two modes only affect Monitor B;
Monitor A continuously sequences regardless of mode. In
the Sequencing Mode, Monitor B will show either an
alarm call up of a camera, a camera under a HOLD
condition or normal sequencing of cameras. In the
Blanking Mode, Monitor B will show either an alarm call-
up of a camera, a camera under a HOLD condition or a
blank screen.
Simple front panel controls insure easy operation. They
include: a dwell button for a dwell adjust menu; select
buttons to select each channel; a skip/clear button to skip
channels or to clear alarms; an alarm button to arm the
monitor (Monitor B for the LTC 5108 Series); and a run
button to initiate auto-sequencing or to select the next
camera in the sequence.
Supplied as compact desktop units, these switchers can
also be mounted with a rack-mount kit. A 609 mm (24 in.)
cable with 15-pin connectors is provided for connecting a
motion detector or remote alarm closures to the switcher.
