RS232
Converters between the serial line (COM port) and other data communication lines.
Serial RS232 port, also known as a COM port, serial line or RS-232 is one of the oldest computer interface. It can be found in many industrial and consumer devices. Until recently, the serial port is equipped with a RS232 in most desktops and on laptops.
It was originally used for modem connection - therefore contains a total of 9 signals. Most devices today, but you only need a three: RxD, TxD and GND (two lines of data and power down).
The downside is a short RS232 maximum cable length - according to only 15 meters (renewable), low noise immunity and risk of ground loops (connecting two devices powered from different potentials may be damaged or destroyed equipment).
As a 100% protection against ground loops is galvanically isolated RS232. If you find some of the drawbacks to RS232 serial port, it is appropriate to convert the heavy-duty industrial RS485 or RS422 or the now ubiquitous Ethernet (network).

TCP2RTU - MODBUS TCP to MODBUS RTU Gateway
TCP2RTU is a transparent converter of the MODBUS TCP protocol, running over Ethernet, into the MODBUS RTU protocol, running over RS232, RS485 and RS422 lines. TCP2RTU is suitable for systems where a device communicating via the MODBUS TCP protocol is the Master and devices using the MODBUS RTU protocol are of the Slave type.
Price: 152 € ex VAT
Wie232 - Wiegand interface to RS232
Wie232 converts Wiegand protocols to a format suitable for a serial port (RS232, COM port). The output of Wie232 is the number of the card read by the reader in the form of text in the ASCII format or in binary format. This enables further processing of the card number by a PC software or another system to be carried out very easily.
