Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

REPEATER USER’S GUIDE
Chapter 1. Product Overview
1.1
INTRODUCTION
The repeater contains three critical components to correct and then retransmit the
HD-SDI signal:
• Adaptive Equalizer to return the signal to its original amplitude and modulation
• Reclocker to resynchronize the signal and bring it back to its original condition
• Cable Driver to retransmit the signal with its original characteristics restored
Furthermore, the repeater design allows for unique benefits:
• Power can be transmitted from the recorder side to the camera over the coax cable.
• Up to five repeaters may be powered from the coax cable; if one or two repeaters
are used, the power may also be adequate to power the camera on the remote end.
• Five or more repeaters can be connected if power is added in the middle of the link.
• A control signal (RS485) can be transmitted from the recorder (DVR) side to the
camera over the coax cable.
• Simultaneous video signal transmission, camera control and power over a single
cable allows full re-use of legacy coax infrastructure.
1.2
REQUIREMENTS
• 75Ω coaxial cable with 75Ω BNC connectors on each end (maximum length
based on cable type – see specifications).
• HD-SDI camera or source (with or without power over coax capability).
• HD-SDI DVR or capture source (with or without power over coax capability).
• 24V DC power supply (not provided).
• 12V DC power supplies can be used if only two repeaters are used and there is no
need to power the camera over the coax (not provided).

1.3
SETUP
Each repeater supports a link of up to 200m with a data rate of 1.485 Gbps and 130m at
2.97 Gbps (depending on cable quality). Longer lengths can be supported with lower-speed
cameras; e.g., 720m for SDI cameras. Up to five repeater units can be daisy-chained
together, all powered over the coax cable by power injected to the first repeater.
Follow these steps:
1. Connect the 24V DC or 12V DC power supply (for the DVR side) and the RS485
in/out cables to the plug connector.
2. Plug the plug connector into the repeater (on the camera side or DVR side).
3. When using multiple repeaters and the RS485 uplink, connect the RS485 Out
cable to the camera (or breakout board) at the camera side.
4. When using multiple repeaters and the RS485 uplink, connect the RS485 In
cable to the DVR (or breakout board) at the DVR side.
5. Connect the 75Ω coaxial cable to the 75Ω BNC connector on the repeater.
6. If powering a camera or remote source over the coax, draw power from the VCC
and GND pins of the plug connector at the camera side.
Note 1:
2:
DS50002303B-page 10
If used, repeaters 2-5 are powered via the first repeater.
Camera control is one-way only, from the DVR to the camera.

The characteristic impedances of the coaxial cables and connectors must all match.
The EQCO-SDI-30-7502 Repeater must have 75Ω (± 3Ω) impedance. Figure 1-4
shows the difference between a 50Ω connector versus a 75Ω connector. A 75Ω coaxial
cable with 75Ω connectors must be used.

1.5
CABLE CONNECTION
When using the repeater at the DVR side, the 24V DC or 12V DC power supply can be
connected to the plug connector. The cable used for the RS485 input signal should be
connected to the RS485 pins of the plug connector. Make sure that all the cables are
connected in the right order, as shown in Figure 1-5. Insert the plug connector into the
repeater box at the DVR side.
When using the repeater at the camera side, the camera can be powered (when no more
than two repeaters are used) by connecting the power to the VCC and GND of the plug
connector. Connect the RS485 output pins to the right pins of the Mini-Combicon plug
connector as illustrated in Figure 1-6. Make sure that all the cables are connected in the
right order. Insert the plug connector into the repeater box at the camera side.
Note:
DS50002303B-page 12
The camera can be powered if only two repeaters are used in-line. It is
necessary to power the first repeater with 24V. Using more than two
repeaters will not allow sufficient power supply for powering the camera. In
this case, external power must be supplied to the camera.
