T-7713 RS-232 TCP/IP
Simple serial-to-Ethernet bridging. The T-7713 is a compact RS-232 to TCP/IP protocol converter that allows serial devices to communicate over an IP network. Perfect for connecting legacy serial equipment (fire alarm panels, access control systems, third-party controllers) to the T-7700 series IP audio system.

The T-7713 operates as a transparent serial-to-Ethernet bridge. Any data received on the RS-232 port is packetized and sent over TCP/IP to a configured host. Conversely, TCP/IP data received from the network is output on the RS-232 port. No protocol conversion or modification – just pure serial data over IP.
The T-7713 is a compact and cost-effective RS-232 to TCP/IP protocol converter that enables serial devices to communicate over an IP network. It's the perfect solution for integrating legacy equipment with modern IP-based systems like the ITC T-7700 series.
Why Use a Serial-to-Ethernet Converter? Many industrial devices – fire alarm panels, access control systems, third-party controllers – still use RS-232 serial communication. The T-7713 bridges these devices to your IP network, allowing:
Simple Plug-and-Play: The T-7713 requires no configuration for basic operation. Connect your serial device to the DB9 port, connect to your network via RJ45, and apply 12V DC power. Data flows transparently in both directions.
Fixed 9600 Baud Rate: The T-7713 operates at 9600 bps, 8-N-1 – the most common serial configuration for industrial equipment. This ensures compatibility with a wide range of devices.
Compact Wall-Mount Design: The small enclosure can be wall-mounted or simply placed near the serial device. LED indicators show power and data activity.
Reliable and Isolated: Basic isolation protects against ground loops and electrical noise common in industrial environments.
Standard DB9 male connector. Connect any serial device with RS-232.
10/100 Ethernet with RJ45. Data accessible anywhere on your network.
Common industrial baud rate. 8-N-1 format for broad compatibility.
Compact enclosure with mounting tabs. Easy installation anywhere.
| Pin | Signal | Direction |
|---|---|---|
| 2 | RXD (Receive Data) | Input to converter |
| 3 | TXD (Transmit Data) | Output from converter |
| 5 | GND (Ground) | Common |
| 1,4,6,7,8,9 | Not connected | - |
Note: Only pins 2,3,5 are used. This is a 3-wire RS-232 implementation suitable for most industrial devices.

Connect fire alarm panel RS-232 output to T-7713. T-7713 connects to network switch. T-7700 server connects to same network and opens TCP connection to T-7713 port 5000. Fire panel serial data (zone alarms, troubles) is received by T-7700 and can trigger audio messages, email alerts, or logging.
Serial Device → T-7713 → Network Switch → T-7700 Server
Example: Fire alarm panel sends "ZONE 3 ALARM" string via RS-232. T-7713 converts to TCP/IP and sends to T-7700. T-7700RP triggers "Evacuate Floor 3" message and logs event.
The T-7713 operates at a fixed baud rate of 9600 bps, 8 data bits, no parity, 1 stop bit. Ensure your serial device is configured to match these settings. Other baud rates are not supported.
Multiple T-7713 units can be used in the same system – each with its own IP address. The T-7700 server can connect to multiple converters simultaneously, allowing integration with many serial devices over the network.

Fire panel RS-232 port configured for 9600 8-N-1, sends zone alarm strings. T-7713 converts to TCP and sends to T-7700 server. T-7700RP software parses strings and triggers appropriate emergency messages. All alarms logged for compliance.
