WebWith this in mind, terminations will be briefly discussed in their simplest form as they relate to RS-485. A terminating resistor is simply a resistor that is placed at the extreme end or ends of a cable (Figure 4). The value of the terminating resistor is ideally the same value as the characteristic impedance of the cable. Figure 4. WebNote that in the case of the serial Modbus protocol, levels 3 to 6 are not used while these are part of a communication structured on an Ethernet network. In the following articles of the “Modbus over RS485” series, the three levels used by the serial protocol will be analyzed in detail by referring to the official documentation of Modbus. In
