1. Before you begin

Re-terminations should be performed by a competent technician.
We cannot guarantee or warrant any repairs made by any employee outside of our business,

including other unaffiliated service centres.
It is possible to cause further damage to systems, consequential damage caused by poor

worksmanship will not be covered and the warranty will be considered void. This document is
intended as a guide for customers wishing to re-terminate the reels, however we cannot accept
responsibility for any damages resulting from poor application of our guide.

Due to continuous development of our product details may change. We only offer this guide to
support those customers who agree to assume responsibility for maintaining their own product.
We can offer training and support packages for customers on how to perform this competently.
Enquire with Sales or Service.

Before any re-termination ensure the system is disconnected from the power supply and

mains to ensure safe working. The cameras can become hot, do not look directly into
the camera due to the bright lights, they may cause temporary blindness or longer-term issues.

Potentially hazardous current and voltage sources contained within system when live.

Gloves and other appropriate PPE are strongly advised based on your risk assessment
due to various mechanical, hygienic, electronic and other hazards. If the system is being re­terminated in a clean area ensure it has been suitably cleaned for the purpose.

Before you attempt any re-termination it is worth checking the video settings are correct for your
reel. For each different length of reel a different amplifier is used to boost the video signal. If this
is set incorrectly it will give a poor signal that may be misinterpreted as a cable fault.

You will need a colour copy of this guide due to colour coded wires and information.
Be aware of and take precautions against ESD. It is advised as part of your risk assessment you

consider the MSDS sheets available online from the 3rd party products required for some repair
operations. Consider PPE as part of this review.

Warning
Use extreme caution when using tools or industrial products or preparations.
When using the junior hacksaw, avoid inhaling or ingesting the glass fibre dust. Consider PPE.
When using the epoxy potting compound, avoid contact with skin.

Slide back the shroud nut and carefully secure
the connector in a vice.

Using a 2mm – 3mm screw-driver or similar,
carefully prise out the circlip that secures the
slip-ring PCB. One end of the circlip is tapered
to facilitate this.

Using a craft knife or similar, lift out the slip­ring PCB and remove the mini-Molex®
connector from the back of the PCB.

3. Slipring Replacement – All Versions

There are two types of slipring PCB, they are not interchangeable and should never be mixed.
Poor video quality will result.

The 10/RP2809-4 ROD-END slipring PCB is at the end of the ROD and has a 6-way connector.

Kit Contains: Rod termination Slipring PCB, O-ring, Circlip

The SONDE-END Slipring PCB goes at the end of the SONDE, it has a different PCB and a 4-way
connector to prevent accidental use (the PCB is visually similar - beware).

Order: 09/RP2816ZBD-V0 (PCB), 04/XVH62S02 (circlip), 07/B01204016 (o-ring).

Plug the mini-Molex connector into the rear of the new slip-ring PCB then push the wires and the
PCB down into the connector being careful not to squash or damage any wires.

Secure the PCB in position with the new circlip, ensuring the circlip is properly seated in its
groove.
Remove the old O-ring. Lightly grease the new O-ring with PTFE grease and fit to the connector.
