DESCRIPTION
The LTC 5121/60, LTC 5121/50, LTC 5141/60 and
LTC 5141/50 are automatic sequential video switchers.
The LTC 5121/60 and LTC 5121/50 have 2-camera
inputs and 1-monitor output; the LTC 5141/60 and
LTC 5141/50 have 4-camera inputs and 1-monitor
output.
Bosch Security Systems | 13 February 2004
4.3
Video Inputs
The LTC 5121/60 and LTC 5121/50 both have two
video inputs labeled CAM 1 and CAM 2. The
LTC 5141/60 and LTC 5141/50 both have four video
inputs labeled CAM 1, CAM 2, CAM 3, and CAM 4.
The LTC 5141/60 and LTC 5141/50 incorporate an
auto-skip feature on CAM 3 and CAM 4. If video is
not supplied to video input 4, the unit will skip over
CAM 4 when sequencing (run mode). If video is not
supplied to video input 3, the unit will skip over
CAM 3 and CAM 4 when sequencing. When using
only 3 video inputs, use inputs CAM 1, CAM 2, and
CAM 3. When using only 2 video inputs, use inputs
CAM 1 and CAM 2.
All video inputs are 75Ω terminated.
4.4
Monitor Output
The monitor output is designed to look into a 75Ω
load. Therefore, if you loop the monitor output line
through monitors or other equipment, be sure their
terminations are set to Hi-Z. Only the last unit on the
line should have its termination set to 75Ω.
LTC 5121, LTC 5141 | Instruction Manual | Operation

OPERATION
5.1
RUN Button and Indicator
Momentary depression of the RUN button initiates
automatic sequencing known as the run mode. The
Green LED above this button will indicate the switcher
is in the run mode.
5.2
DWELL Control
This control is located on the rear panel. This
adjustment controls the rate at which the cameras are
sequenced during the run mode. Rotating the control
clockwise slows the rate of sequencing (increases the
dwell time). Rotating the control counter-clockwise
causes the switcher to sequence faster (decreases the
dwell time). The dwell time is approximately 2 seconds
when the control is turned fully counter-clockwise; full
clockwise rotation of the control provides a dwell time
of approximately 45 seconds.
5.3
Camera Buttons and Indicators
These buttons are used to call-up a camera and stop
automatic sequencing. When a camera button is
pressed, that camera will be called-up to the monitor
screen, the camera LED indicator will light, and the
RUN LED indicator will go out.
