Coxmate SR 

The Coxmate range of electronics assistants for coxes brings the benefits of current electronics technology to rowing. The Coxmate SR is the mid range of the Coxmate family. It’s main functions are a rechargeable audio amplifier, stop watch/timer, stroke rate display and stroke count.

The SR has a long list of other functions, including:-  A backlit display for those dark Winter mornings, a metronome function providing an audible pulse at a preselected stroke rate, the recording and recall of stroke rate and interval times,  increased battery capacity, and a sophisticated battery management system to provide indication of available battery charge and maximise battery life. Connector is fitted for external radio receiver to be plugged in , enabling coach to talk directly to crew.

The Coxmate range is offered with speakers, cable harness’, stroke/seat sensors, microphone and charger. The speakers, stroke/seat sensor and cable harness are compatible with the Nielsen Kellerman Cox-Box™ and Cox-Vox™ units. An SR unit can be plugged directly into an existing Nielsen Kellerman cable harness.

 The following Coxmate kits and components are available:

• SR-Kit: SR control unit with charger, microphone, carry case, mounting plate, silicon grease and manual.

• *CH4-SR/SC-Mod-kit: Cable harness for four with connectors for 2  speakers and stroke/seat sensor.

• *CH8-SR/SC-Mod-kit: Cable harness for eight with connectors for 4 speakers, stroke/seat sensor and section connectors.

  * The 'modular' harness/speaker systems are recommended. Conventional systems are also available

The Coxmate designs are a result of a lengthy and intensive study into the needs of rowing, and how existing systems can be improved. Some of the features are listed below:

• Large capacity NiMH rechargeable battery storage.

• Sophisticated battery management with indication of charge level. Charger turns off when fully charged- avoids degrading batteries by overcharging.

• Increased audio power, reducing distortion, increasing efficiency and increasing battery operating time.

• Automatic power down if speakers are not connected – avoids accidental flattening of batteries.

• Automatic retention of volume setting when turned off/on.

• Large versatile 2 x 16 digit alpha numeric display with backlight. Backlight can be turned on/off.

• Fully featured stop watch/timer.

• Short circuit protection of speaker output.

• Customer replacement of rechargeable batteries.

• A permanent connection of microphone to control box – removing problems associated with unreliable connection.

• Coxmate harness accommodates up to 4 speakers – providing even sound volume through boat, and enabling Cox to communicate with crew but not the competing crew alongside.

• Improved cable harness design:

• All connectors are fitted with strain relief to protect against damage during connection/disconnection.

• All cables are double insulated to provide additional mechanical protection.

• All copper wires are tinned to reduce corrosion potential.

• All connectors are fitted with clear visual markers to assist in aligning of two halves during connection.

• Main harness connector and section connectors have retentive caps, to protect connector when control unit is disconnected.

• The Coxmate units are supplied with a special mounting plate. This can be permanently mounted in boat or strapped to Cox’s arm or leg with Velcro™. The control unit is easily attached/detached to/from this plate.

• Mute button: Will suppress audio if held down.
