3 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.
4 INSTALLATION
4.1 Power
LTC 5121/60 and LTC 5141/60 models operate
from 120VAC, 50/60Hz power. LTC 5121/50 and
LTC 5141/50 models operate from 220-240VAC,
50/60Hz power. The model number and operating
voltage are shown on the label located on the bottom
of the unit. These units are supplied with ground
power cords; grounding should not be defeated.
4.2 Mounting
These switchers are supplied as desk-top units. For rack
mounting, the LTC 9101/00 rack-mount kit is available.
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 75
Ω
terminated.
4.4 Monitor Output
The monitor output is designed to look into a 75
Ω
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 75
Ω
.
