Industrial serial-to-fiber converters SC MM

The ICF-1150 series support 2 serial ports, with a D-sub connector for RS-232 communication and a removable terminal block for RS-422 or RS-485 communication. The 3 ports (2 serial ports and one fiber port) are completely independent. When an ICF-1150 converter receives data from any one port, it will send the data out through the other 2 ports. For example, once the ICF-1150 converter receives a command from the remote master through the fiber port, it will convert the signal and send the command through the RS-232 and RS-422/485 ports at the same time. If the user is monitoring a system running on an RS-485 network, there is no need to use an additional RS-232 to RS-485 converter to connect the laptop computer’s serial port to the RS-485 bus.

Rotary Switch for Setting the Pull High/Low Resistor

The RS-485 interface supports multi-drop or daisy-chain connections, which system engineers will use to connect serial devices such as meters, RTUs, and readers together on the same bus. Since the number of serial devices on the same bus will cause the impedance of the data line to increase, the ICF-1150 allows users to tune the pull high/low resistor. Just rotate the switch to the appropriate value without removing the ICF-1150 from the DIN-rail.

RS-232/422/485 to optical fiber media converters SC SM

The TCF-142 media converter is equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces and multi-mode or single-mode fiber. TCF-142 converters are used to extend serial transmission up to 5 km (TCF-142-M with multi-mode fiber) or up to 40 km (TCF-142-S with single-mode fiber). The TCF-142 can be configured to convert either RS-232 signals, or RS-422/485 signals, but not both at the same time.

Automatic Baudrate Detection

The TCF-142 can automatically detect the serial baudrate. This is an extremely convenient feature. Even if a device’s baudrate is changed, the signal will still be transmitted through the media converter without any data loss.

Ring Operation

The TCF-142 converters can be used to connect serial devices to a fiber ring. To form the ring, connect the Tx port of one TCF-142 to the Rx port of a neighboring converter. Once the ring is set up, simply use the DIP switches to configure the TCF-142 converters for “ring mode.” When one node transmits a signal, the signal travels around the ring until it returns back to the transmitting unit, which then blocks the signal. With the TCF-142, you can set up fiber rings that have a total circumference of up to 100 km.

Automatic Data Direction Control (ADDC®)

ADDC® is a patented hardware data flow solution developed by Moxa to handle RS-485 data direction control. ADDC® senses and controls RS-485 data direction automatically, making it unnecessary to use the hand shaking signal.

Entry-Level RS-232 to RS-422/485 Converters

The Transio A52 and A53 are smart RS-232 to RS-422/485 bi-directional converters that come with all of the great technical specs that Moxa is known for. This includes data direction control built into the hardware for both the RS-422 and RS-485 interfaces, LED indicators for power and signal states, and surge protection and isolation protection. The last two features take care of some of the major problems faced by serial communication connections in industrial environments.

Serial Connection Problems in Industrial Environments

Serial communication and reliability can be adversely affected in a hazardous industrial environment. The wiring associated with serial communication devices could be surrounded by power lines, motors, or equipment that produces static electricity. If this is the case, the serial devices could be damaged by sudden surge waves produced by this type of equipment. In this situation, surge protection that uses TVSS (Transient Voltage Surge Supression) is the solution.

When two serial devices are directly connected, but separated by a long distance, the unbalanced ground voltage could cause serious damage. Unbalanced ground voltage between two serial ports forms a “ground loop,” introducing a large current between the two pieces of serial equipment. In fact, the current could be so lare as to damage the equipment beyond repair. In this situation, the solution is to use isolation protection to provide complete isolation for both communication ports.

What is Surge Protection?

Surges are high amplitude pulses that last only a few millionths of a second in duration. They can be caused by heavy-duty equipment, power lines, short circuits, or large motors. A surge suppressor has the ability to absorb the high energy instantly and effectively to prevent the connected devices from being damaged.

What is Isolation Protection?

Electrical isolation is achieved by using a photo coupler to transform an electric signal into light, and then retransform the light back into an electric signal on the other side of the isolator. In this way, the two electric circuits are completely isolated from each other.
