Frequently Asked Questions

Q: What's the difference between CSE-B63G and CSE-H53N?
A: The CSE-B63G is a board-type module (80x45x17mm) supporting both RS-232 and RS-485, while the CSE-H53N is a standalone converter with enclosure supporting RS-232 only. Choose CSE-B63G for OEM integration and dual-interface flexibility, CSE-H53N for standalone plug-and-play applications.

Q: Can I use both RS-232 and RS-485 simultaneously?
A: No, the module has one UART that can be configured for either RS-232 or RS-485 operation. You select the interface based on your application needs.

Q: Does the module include RS-485 termination resistors?
A: The CSE-B63G includes 3.9kΩ biasing resistors but does not include 120Ω termination resistors. Add external 120Ω termination resistors at both ends of your RS-485 bus as needed.

Q: What are the built-in 3.9kΩ biasing resistors for?
A: The 3.9kΩ biasing resistors help maintain the RS-485 bus in a known state when no devices are transmitting, improving signal integrity and reducing noise sensitivity.

Q: Does the CSE-B63G support IPv6?
A: Yes! Full IPv4/IPv6 dual stack support with ICMPv6, TCPv6, and UDPv6 protocols. It's fully ready for modern IPv6 networks.

Q: What is the maximum baud rate?
A: Up to 921.6 kbps under certain conditions. Standard operation supports up to 230.4 kbps reliably for both RS-232 and RS-485.

Q: How do I configure the module?
A: Three methods: (1) ezManager via Ethernet (easiest), (2) Telnet for remote configuration, (3) AT commands via serial terminal for dynamic control. Choose the method that works best for your deployment.

Q: Can I use this in outdoor applications?
A: Yes! The module is rated for industrial temperatures (-40°C to +85°C) and includes surge protection. However, it's not waterproof—install in a weatherproof enclosure for outdoor use.

Q: What security features are included?
A: TLS v1.2 encryption, IP/MAC address filtering, and password-protected configuration. This provides enterprise-grade security for industrial control applications.

Q: What is AT Command mode?
A: AT Command mode is a patented Sollae Systems feature that allows you to control TCP/IP connections dynamically via serial AT commands. You can establish connections, change IP addresses, and configure network parameters without rebooting the device.

Q: Is the CSE-B63G module compatible with Modbus?
A: Yes, the CSE-B63G can transport Modbus RTU (serial) over TCP/IP networks, enabling Modbus TCP functionality. Configure the module in transparent mode for Modbus applications.

Q: What power supply do I need?
A: Regulated 5V DC power supply capable of at least 200mA (173mA max consumption + safety margin). The module includes reverse voltage protection.
