how to install Black Box Async RS232 Extender over Fiber

• Power down both connected devices and ensure the extender is disconnected from any active power sources before installation.
• Connect the RS232 device to the DB25 male connector on the transmitter side using a standard DB25 RS232 cable, ensuring correct pin alignment and signal direction.
• Attach multimode fiber from the transmitter’s ST multimode port to the receiver’s ST multimode port, making sure the fiber ends are clean and seated securely in the connectors.
• Plug the autosensing power supply into a grounded 110-220 VAC outlet and connect it to the extender’s power input. Verify the power indicator is illuminated.
• Power on both ends and verify link status by testing data transmission between the RS232 devices. If needed, adjust baud rate settings to match the communicating devices for reliable communication at up to 76.8 kbps.
