ServerBridgeX - TCP to Serial

ServerBridgeX turns your Android phone or tablet into a bridge between a TCP/IP network and serial equipment. Plug in a USB-to-serial adapter with an OTG cable, start the server, and any client on your network can talk to that equipment as if it were wired directly to it. HOW IT WORKS 1. Connect your USB-to-serial adapter with an OTG cable and grant permission. 2. Open the device configuration and set baud rate, data bits, parity and stop bits. 3. Tap the play button to start the TCP server. Your IP and port appear in the Summary tab. 4. Point your clients at that address and data starts flowing both ways. FEATURES • TCP/IP server on a configurable port. • Several USB serial devices connected at once, each with its own settings. • Per-device access control: choose which TCP clients may exchange data with each device. • Client-to-client routing: forward one client's traffic to others. • Full serial parameters: baud rate, data bits, parity and stop bits. • Summary view to monitor all traffic, Terminal view to send and receive by hand. • ASCII or hexadecimal data, with a built-in hex keyboard. • CR/LF line ending selectable straight from the input bar. • Persistent message history that survives closing the app. • Export the log to a file and share it. • Keeps running in the background through an ongoing notification, so the link is not dropped while you use other apps. • Built-in setup guide and help screen. WHO IT IS FOR Built for technicians, integrators and maintenance staff working with industrial equipment: DNP3 RTUs and masters, Modbus devices, PLCs, meters, scales, barcode readers and anything with RS-232 or RS-485 behind a USB adapter. It is especially handy when the serial equipment sits in the field and you need to reach it from a laptop or tablet over the network, without running cable. REQUIREMENTS • Android 8.0 or later. • An OTG cable and a supported USB-to-serial adapter (FTDI, Prolific, Silicon Labs, CH34x and CDC/ACM chipsets). • Client and server must be on the same network. PRIVACY Data travels only across your local network and never through an external server. No ads, no sign-up.
