RS-485 Configuration Guide

Termination Resistors

RS-485 networks require 120Ω termination resistors at both ends of the bus:

• Enable termination on the first and last devices only via web interface
• Disable termination on all middle devices
• Software-configurable (no hardware jumpers required)
• Improper termination causes communication errors

Wiring Best Practices

• Use twisted pair cable (Cat5e or better, or dedicated RS-485 cable)
• Keep total bus length under 4,000 feet (1,200m)
• Use daisy-chain topology (not star)
• Avoid stubs longer than 1 meter
• Maintain proper grounding to prevent ground loops
• Use shielded cable in electrically noisy environments

Pin Assignment for RS-485

• Pin 1: TRXD- (Data-)
• Pin 2: TRXD+ (Data+)
• Pin 5: GND (Ground)

Multi-Drop Addressing

For RS-485 networks with multiple devices:

• Each device needs a unique address (configured in serial device)
• sLAN/all-PoE acts as transparent bridge (no addressing required)
• Use Modbus RTU, Profibus, or other multi-drop protocols
• Configure appropriate timeout values for polling applications

PoE Deployment Guide

PoE Switch Requirements

The sLAN/all-PoE requires an IEEE 802.3af compliant PoE source:

• PoE Standard: IEEE 802.3af (PoE, not PoE+)
• Power Class: Class 0 (0.44W to 12.95W)
• Actual Consumption: 0.6W (operating & standby)
• Voltage: 48V DC nominal

Compatible PoE Sources

Managed PoE Switches:

• Enterprise-grade switches with per-port PoE management
• Remote power cycling capability
• Power monitoring and budgeting
• VLAN and QoS support

Unmanaged PoE Switches:

• Simple plug-and-play operation
• Lower cost for small deployments
• No configuration required

PoE Injectors (Midspan):

• Single-port PoE injectors for non-PoE switches
• Multi-port injectors for multiple devices
• Ideal for adding PoE to existing infrastructure

Cable Requirements

• Cable Type: Cat5e or better (Cat6, Cat6a recommended)
• Maximum Length: 100 meters (328 feet) per IEEE 802.3af standard
• Shielding: Use shielded cable in electrically noisy environments
• Quality: Use quality cables to ensure reliable PoE delivery

Temperature Considerations

PoE Mode Operating Range: -20°C to 70°C (-4°F to 158°F)

• Most industrial environments fall within this range
• For extreme cold (< -20°C), use Micro-USB power instead
• For extreme heat (> 70°C), use Micro-USB power instead
• PoE mode provides adequate range for most applications

USB Mode Operating Range: -40°C to 85°C (-40°F to 185°F)

• Extended range for extreme environments
• Use when PoE temperature limits are exceeded
• Requires separate power adapter

Frequently Asked Questions

Q: What's the difference between the sLAN/all-PoE and the sLAN/All?
A: The sLAN/all-PoE includes Power over Ethernet (IEEE 802.3af) capability, allowing it to be powered directly from a PoE switch. The V2.0 model requires external 5V DC power. The PoE model is also slightly larger (102.5mm vs 72mm length) to accommodate PoE circuitry. Both models have identical serial and network capabilities.

Q: Do I need a PoE switch, or can I use a PoE injector?
A: Either works! You can use a PoE-enabled network switch or a PoE injector (IEEE 802.3af). PoE injectors are ideal for adding PoE capability to existing non-PoE switches.

Q: Can I use regular (non-PoE) Ethernet and power it via Micro-USB?
A: Yes! The sLAN/all-PoE has dual power options. You can use PoE for clean installations or Micro-USB (5V DC) when PoE isn't available. This provides maximum deployment flexibility.

Q: What's the operating temperature range when using PoE?
A: When powered by PoE, the operating temperature range is -20°C to 70°C (-4°F to 158°F). When powered by Micro-USB, the range extends to -40°C to 85°C (-40°F to 185°F).

Q: How much power does the sLAN/all-PoE consume?
A: Very little! PoE mode consumes only 0.6W (operating & standby). USB mode consumes 1.0W operating, 0.9W standby, with a maximum of 1.2W. This makes it extremely energy-efficient.

Q: How do I switch between RS-232, RS-422, and RS-485 modes?
A: All configuration is done through software via the web interface or SGConfig utility. Simply select the desired interface type in the Serial Settings page and reboot the device. No hardware jumpers required.

Q: What's the maximum number of devices on an RS-485 network?
A: The sLAN/all-PoE supports up to 32 devices per RS-485 bus. For larger networks, use RS-485 repeaters.

Q: Can I configure the device via web browser on a 10Mbps network?
A: No, web configuration requires a 100Mbps network connection. For 10Mbps networks, use the SGConfig utility instead, which works with both 10Mbps and 100Mbps connections.

Q: What operating systems are supported?
A: The device works with any OS that supports TCP/IP (Windows, Linux, macOS, Unix, etc.). The COM Port Redirector and SGConfig utilities require Windows 7 or above, but the web interface works in any modern browser.

Q: How do I reset the device to factory defaults?
A: Press and hold the RST button on the rear panel for more than 3 seconds. The device will reset to factory default settings (IP: 192.168.0.223, ID: slan, Password: 99999999).

Q: Can I use straight or crossover Ethernet cables?
A: Either! The sLAN/all-PoE supports Auto-MDIX, which automatically detects and adapts to both cable types.

Q: What is the default IP address?
A: The default IP address is 192.168.0.223 with subnet mask 255.255.255.0 and gateway 192.168.0.254.
