1. Important Safety Information
This manual uses the following signal words:
Before installing or servicing
- Installation should be performed by a qualified installer or electrician in accordance with the National Electrical Code (NEC), the Canadian Electrical Code (CEC) where applicable, and all local codes.
- Power the RGB7 only from a 24 V AC transformer. A listed Class 2 transformer is recommended. Do not connect the timer to 120/240 V AC or to a DC supply.
- Verify the harness pinout against Section 3 before plugging in. Connecting a harness wired for a different timer model can damage the timer and connected equipment.
- Car wash bays are wet locations. Mount the timer so the faceplate seals against the wall or panel, route wiring so water drains away from the connector, and do not mount the timer where it can be directly sprayed by a wand.
- Do not open the timer housing, modify the circuit board or install unapproved firmware. There are no user-serviceable parts inside other than the replaceable faceplate. Modifications void the warranty and may void the user's authority to operate the equipment (see Section 12).
- Do not use the timer if the housing, faceplate, connector or cable is damaged.
2. Product Overview
The RGB7 is a coin, bill and card bay timer with a full-color LED display. It replaces a Dixmor LED 7 using the same 10-position, 3.96 mm Molex connector and pinout, so in most bays it plugs into the existing harness with no rewiring. Settings are made from a phone, tablet or computer through the timer's built-in setup page. Normal timer operation does not need an internet connection. When connected to Wi-Fi, the timer can also be managed through your account at POGOWash.com.

4. Setup Mode and the Setup Button
All settings are made through a setup page served by the timer itself. When setup mode is on, the timer creates its own Wi-Fi network. You don't need internet access or an app.
Opening the setup page
- With the timer powered for at least 5 seconds, press the setup button once through the access hole on the back of the timer. Use a non-conductive tool such as a plastic stylus.
- A single red dot in the bottom-right corner of the display shows that setup mode is on.
- On your phone, tablet or laptop, join the Wi-Fi network named
POGO-Wash-XXXX.XXXXis unique to your timer, so write it on the record page at the front of this manual. - The setup page usually opens by itself. If it doesn't, open a web browser and go to
http://192.168.4.1. - Make your changes and save. The timer applies saved settings right away.
Setup mode turns off on its own after about 10 minutes without activity on the setup page, as long as no wash is running. The timer restarts and returns to normal operation. Press the setup button again if you need more time.
Setup button functions
| Action | Result |
|---|---|
| Press once | Turns on setup mode. |
| Press 3 times within 5 seconds | Clears the coin/bill wash that's running and returns the timer to its greeting. |
| Hold for 5 seconds | The display shows a factory-reset countdown. Release the button now to cancel. |
| Hold for 10 seconds | Factory reset. All settings, including Wi-Fi and passwords, go back to factory defaults and the timer restarts. |
The button is ignored for the first 5 seconds after power-up, to prevent accidental presses during startup.
You can explore the setup page before installing at pogowash.com/setupPreview. Once your timer is connected to Wi-Fi and linked to your account, the same settings can also be changed remotely from your POGOWash.com dashboard.
5. Settings Guide
The setup page groups settings as follows. Settings may be added or renamed in firmware updates.

Online settings
Wi-Fi, remote activation, revenue logging and firmware update settings are described in Section 6.
6. Wi-Fi and POGOWash.com
Wi-Fi is optional. Without it, the timer works as a standalone timer using the settings saved on it.
Connecting to Wi-Fi
- Open the setup page (Section 4) and find WiFi Settings.
- Turn on Enable Wifi and enter your network name and password exactly. Both are case-sensitive. The network name must be used only on 2.4 GHz. Many routers broadcast 2.4 GHz and 5 GHz under the same name, and the timer can't connect reliably to those networks. If yours does, give the 2.4 GHz band its own name in your router settings (for example, add "-2G" to the end) or set up a separate 2.4 GHz guest network, and enter that name here.
- Save. While setup mode is on, the bottom-left dot on the display shows Wi-Fi status: green when connected to Wi-Fi, red when not. A second green dot next to it means the timer is also connected to the POGOWash server.
Leave the WebSocket Server settings at their defaults unless POGO Engineering support asks you to change them.
Adding the timer to your account
Sign in or create an account at www.pogowash.com. Go to Devices > Add Device and enter the serial number found on your timer.
Online features
| Feature | Description |
|---|---|
| Remote Activation | Start a wash from your dashboard, for example to assist a customer or wash down the bay. Set a Remote Activation Password on the timer and enter the same password on POGOWash.com. The timer ignores remote starts that don't include the correct password. Choose a strong password and don't reuse it elsewhere. |
| Revenue Logging | Sends coin, bill and card pulse records to your account for revenue reports and coin-vault cleanout tracking. |
| Wash codes | Lets customers redeem prepaid wash codes on connected timers. |
| Automatic Firmware Updates | Lets the timer download approved firmware from POGO Engineering. Set Allowed Update Time to a time when the wash is normally closed. A timer won't update during a wash. Updates can also be started from your dashboard. |
7. How the Timer Operates
Count-down (coin and bill)
Each coin or bill pulse adds value and time. When the inserted amount reaches Cost to Start, the timed-load output turns on and the display counts down. Customers can add money at any time to add time. The horn warns when time is low, if enabled. When time runs out the output turns off, and if Allow Restart is on, the customer has the restart window to add more money.
Count-up (card)
When a card reader starts a transaction, the display shows the verifying and approved messages, then the timed-load output turns on and the display counts up time or amount spent. When the card transaction ends, the output turns off and the charge is based on elapsed time, but never less than the Minimum Card Charge.
Power interruption
With Power Loss Detection on, a count-down wash that was running when power failed resumes with its remaining time once power returns. Settings are always kept through a power loss.
8. Commissioning Checklist
Complete these checks before returning the bay to customers:
- The display lights up and shows your greeting.
- Pricing, time per pulse and Cost to Start are correct for your posted prices.
- A real coin and bill each add the expected amount and time.
- The pump or valve turns on when the wash starts and off when time runs out.
- The horn sounds at the warning time, if used.
- The card reader starts and ends a count-up wash and charges correctly, if used.
- If online: the timer appears on your POGOWash.com dashboard and test pulses appear in revenue logging.
- Fill in the record page at the front of this manual.
The setup page also includes service tools for testing the LEDs, horn, timed load and simulated inputs.
9. Care and Maintenance
- Clean the faceplate with a soft cloth, water and mild dish soap. Rinse with clean water.
- Do not use solvents, ammonia-based glass cleaners, tire or wheel cleaners, acid or high-pH chemicals, or abrasive pads on the faceplate. These can cloud or crack polycarbonate.
- Do not aim a high-pressure wand at the timer.
- Check the connector and harness once a year for corrosion or loose pins.
- Replacement faceplates are available from POGO Engineering. A scratched or damaged faceplate can be replaced in the field without replacing the timer.
10. Troubleshooting
| Problem | Possible cause | What to do |
|---|---|---|
| Display stays dark | No 24 V AC, connector not fully seated, or wrong harness pinout | Measure 24 V AC between pins 6 and 7 at the harness. Reseat the connector. Compare the harness with the pinout in Section 3. |
| Setup network doesn't appear | Button pressed within 5 seconds of power-up, or setup mode timed out | Wait 5 seconds after power-up and press the button again. Look for the red dot in the bottom-right corner. |
| Setup page doesn't open | Phone switched back to mobile data or another network | Stay connected to POGO-Wash-XXXX and go to http://192.168.4.1. Turning off mobile data temporarily can help. |
| Coins or bills don't register | Wiring, acceptor pulse settings, or value set to 0 | Check pins 1, 2 and 8 and the acceptor's pulse output. Check the Coin/Bill Value settings. |
| Money registers but the bay doesn't start | Cost to Start not reached, or timed-load wiring | Check Cost to Start. Check pin 10 and the contactor or relay coil. |
| Horn doesn't sound | Horn off, warning time set to 0, or wiring | Check the horn settings and pins 4 and 5. |
| Won't connect to Wi-Fi | 5 GHz network, a network name shared by 2.4 GHz and 5 GHz, wrong password, or weak signal | Use a network name that's only on 2.4 GHz (see Section 6) and re-enter the name and password. Improve the signal with an access point or extender near the bay. |
| Not showing on the dashboard | Not linked to your account, or server connection down | Confirm both status dots are green in setup mode, then follow Section 6 to link the timer. |
| "Tampering" message | Magnet detected near the timer | Inspect the bay for tampering devices. Turn the detection off only if a nearby fixture causes false alarms. |
| Settings lost | Setup button held 10 seconds (factory reset) | Reconfigure the timer. Press the button briefly when entering setup. |
11. Factory Reset
A factory reset erases all settings, including pricing, messages, the Wi-Fi network and the remote activation password.
- With the timer powered for at least 5 seconds, press and hold the setup button.
- After 5 seconds the display shows a reset countdown. Release now to cancel.
- Keep holding until 10 seconds have passed. The timer resets and restarts.
- Reconfigure the timer (Sections 4 to 6) and repeat the commissioning checklist.
If you sell or transfer the timer, do a factory reset first and remove it from your POGOWash.com account.
