Remote Internet Access Setup for RTC-1000 and SB-100PRO Time Clocks

The RTC-1000 and SB-100PRO network time clocks from Icon Time Systems can be accessed securely over the internet, allowing managers to view punches, configure settings, and manage attendance from any location. This setup uses standard network connectivity and router port forwarding to make the clock reachable outside your local office network. Once configured correctly, the system operates just like accessing the clock internally — only from anywhere in the world.

Network Requirements and Initial Clock Setup

Before enabling external access, the clock must be properly connected and working inside your local network. A broadband internet connection such as cable, DSL, or fiber is required, along with a router that supports port forwarding — which most modern routers do. The time clock should be connected directly to the router using an Ethernet (CAT5 or better) cable. Once connected, confirm that you can access the clock internally by entering its local IP address into a web browser. These addresses typically begin with 192.168.x.x. If the clock’s web interface loads correctly on your internal network, it is ready for remote configuration. A static external IP address from your internet provider is optional but helpful, as it prevents the address from changing over time.

Router Port Forwarding Configuration

To allow internet traffic to reach the clock, your router must forward incoming requests to the clock’s internal IP address. Standard configuration forwards external Port 80 to the clock’s private IP using TCP protocol. This allows web browser access just like local connections. If Port 80 is unavailable or already in use, you can forward an alternate port such as 9844. When using an alternate port, it must be added to the address when connecting. For example: http://your.external.ip.address:9844 Router menus vary by manufacturer, so consult the router’s documentation or your IT provider if needed. Once forwarding is saved, the clock should be reachable from outside your network.

Connecting From Outside the Office

After port forwarding is complete, access the clock using your router’s external IP address. This address can be found by checking the router’s WAN settings or by visiting an IP lookup service from a local computer. If connection fails, common causes include active firewalls blocking traffic, incorrect IP addresses, wrong port numbers, or additional router filtering rules. Verifying each of these usually resolves access issues quickly.

Remote Access Benefits and Best Practices

Once enabled, internet access allows real-time monitoring, faster troubleshooting, and easier multi-location management without visiting the clock site. Managers can review punches, adjust settings, and oversee attendance from any connected device. For security, consider using strong router passwords, limiting forwarded ports when possible, and consulting IT professionals for complex network environments.

Operational Summary

External access for the RTC-1000 and SB-100PRO is achieved by confirming local connectivity, configuring router port forwarding, and connecting through your external IP address. When set correctly, the clock becomes fully manageable from anywhere with internet access — improving oversight, flexibility, and response time for workforce management without additional software or hardware.
