PACKAGE CONTENTS
This package contains:
One CTMS-8RKPS Rack Mount Satellite Multiswitch
One CTMS-8RKPS Power Supply
One CTMS-8RKPS Installation Manual
PRODUCT DESCRIPTION
The CTMS-8RKPS is a professional grade rack mountable satellite multiswitch providing RHCP
and LHCP switching for up to 8 satellite receivers. Designed for commercial grade satellite
headends, the CTMS-8RKPS inputs are selected by 17V to 18V from the satellite receiver for left
hand circular polarization, and 13V to 14V for right hand circular polarization. The CTMS-8RKPS
permits satellite intermediate frequency (IF) distribution of 950 – 2150 MHz from the outputs of a
dual LNB to up to 8 satellite receivers. The unit’s quality design and engineering make the
CTMS-8RKPS an excellent choice for cost effective SMATV installation, operation and
maintenance.

INSTALLATION AND OPERATION
NOTE TO SYSTEM INSTALLER
System installer must adhere to Article 820-40 of the NEC that
provides guidelines for proper grounding and specifies that the
cable ground shall be connected to the grounding system of the
building, as close to the point of cable entry as practical.
1. UNPACKING and HANDLING
Each unit is shipped with all equipment assembled, and factory tested.
Ensure that all accessories are removed from the container before discarding packing material
2. MECHANICAL INSPECTION
Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is
clean, and no connectors are broken, damaged, or loose. If equipment appears to be damaged
or defective please contact us at 1-610-429-1511 for assistance.

4. HARDWARE CONNECTIONS
a. The CTMS-8RKPS is designed for installation in a standard 19” EIA rack.
b. Connect a 75ohm coaxial cable with F-connectors from the LHCP LNB Output to the
CTMS-8RKPS’ LHCP Input port.
c.
Connect a 75ohm coaxial cable with F-connectors from the RHCP LNB Output to the
CTMS-8RKPS’ RHCP Input port.
d. Connect a 75ohm coaxial cable with F-connectors from one of the CTMS-8RKPS’
Output ports to the input of a satellite receiver. Repeat for each satellite receiver.
e. Connect antenna using 75ohm coaxial cable with F-connectors to the CTMS-8RKPS’
Antenna Input port.
f.
Connect the power supply’s 3.5mm plug to the CTMS-8RKPS’ Power Input port. Plug
the power supply into a 120 VAC, 60Hz receptacle.
g. Each satellite receiver can select programs in either RHCP or LHCP. To select RHCP,
a 13/14 DC voltage is used. To select LHCP, a 17/18 DC voltage is used.
5. ADJUSTMENT
No adjustments to the CTMS-8RKPS can be made.
However, it is important to ensure all headend equipment including modulators, combiners,
and amplifiers are adjusted to the proper signal levels per the headend design specifications.
6. TROUBLESHOOTING
a. Ensure you are using quality multiple shielded high frequency cables with quality radial
or compression F-connectors.
b. Ensure the F-connector’s center conductor is making solid contact with the
CTMS-8RKPS Input and Output ports, the LNB connectors, and the satellite receiver
input connectors.
