Mastering Geotab
★ Geotab Products · Technical Information
The IOX-BUZZ shows its status only by sound: it has no lights and repeats every GO device beep at up to 75 dBA. This page plays the documented sounds, explains them, and covers specs, mounting and install checks.
There is nothing to watch on this module. The IOX-BUZZ is a loud external speaker for the GO device, with no LEDs documented, and every sound it makes copies a beep the GO device is already playing. Which beeps play, and when, comes from the feedback settings and rules in MyGeotab. Tap any button below to see it and hear what it means.
🔊 The IOX-BUZZ has no lights. It speaks only in beeps. Turn your sound on.
Easy way to remember it: Buzz means a rule fired. MyGeotab sets the rhythm. Quiet means no alert, or feedback is switched off.
Tap a button to see it
Each button plays the sound on the IOX-BUZZ above, says out loud what it means, and tells you what to do.
| Sound | Meaning | What to do |
|---|---|---|
| Steady beeping while driving fast | Speed indicator: the vehicle is over the set speed, and it stops only below the lower off speed | Slow down |
| One brief beep at speed | Speed warning mode, which swaps steady beeping for a short one | Ease off the throttle |
| Beeping while parked and running | Idle limit passed; three minutes unless the office changed it | Shut the engine off |
| Short beep groups, such as three | A MyGeotab rule with beep feedback fired | Ask the office which rule plays that pattern |
| Six rapid beeps at power-up (GO9 family) | The GO device detected power | Nothing; normal at install |
| Silence | No alert, feedback off, or buzzer disabled for that GO device | Have our technicians check settings if alerts are expected |
Geotab publishes no beep codes of the buzzer's own and no exact timings for feedback beeps, so the player's rhythms are approximate.
Drivers simply listen. When the vehicle passes the set speed, idles too long or breaks a rule with beep feedback, the IOX-BUZZ repeats the GO device's beep loud enough to cut through road noise. Nothing on it needs pressing or resetting.
The office controls everything it says. Speed beeps use an on speed and a lower off speed, idle beeping uses a minutes setting, and rules pick their own beep feedback. One master setting disables the GO device's buzzer completely, which silences the IOX-BUZZ as well, so check it first when a truck goes quiet.
It needs no vehicle harness. The buzzer takes power and CAN data from the IOX expansion port on any GO7 or newer device, and passes both on through its female socket to the next module. Notes for planning:
| Item | Value |
|---|---|
| Indicators | None; sound only |
| Loudness | 75 dBA measured at 30 cm |
| Power | 12 V / 24 V nominal; 40 mA typical, 100 mA max, 0.4 mA sleep |
| Chain | CAN at 500 kbps; male mini-USB Type-B in, female out |
| Size and weight | 2205 mm overall; 60 x 16 mm at the widest; 96 g |
| Housing | PC+ABS clamshell with two mounting holes |
| Temperature | -40 to +85 °C |
| Works with | GO7 and newer devices and variants |
Sit in the driver's seat with the engine running and the blower on, and make sure the power-up or troubleshooting beeps are plainly audible from there. Confirm the buzzer is fastened through its holes rather than hanging on the lead, and that nothing will rattle against it. Look at the shunt: gone if another module follows, present and zip tied if the buzzer ends the chain. Before handing back the keys, confirm in the device settings that the master buzzer setting is not disabled, otherwise the new hardware will never make a sound.
Buzz means a rule fired, and MyGeotab sets the rhythm. The buzzer has no beep codes of its own; it repeats whatever the GO device plays, only louder and closer to the driver.
Either the speed beeps were never switched on for that vehicle, or the master buzzer setting for the GO device is disabled, which stops driver feedback of every kind. Our technicians check the device settings and the rules together.
Yes, if the fleet wants audible alerts. Geotab states that GO RUGGED units need the IOX-BUZZ before beep mode is available, so without one those devices stay quiet.
If drivers say they never hear their alerts, our technicians can relocate or add the buzzer, test it from the driver's seat and confirm the feedback settings while on site. To book that visit, dial 803-513-1009 or open Get a Quote.
