PSI-MODEMSHDSL/SERIAL 1.5 Interface basics 1.5.1 RS-232 The RS-232 interface is a widely used serial interface, which is defined in standards EIA232 and CCITT V.24. This interface carries out data exchange between two devices (point-to-point connection). It transmits and receives data in full duplex mode over lines of up to 15 m. The maximum transmission speed is 230.4 kbps.
Description of the SHDSL permanent line modem 1.5.2 RS-422 The RS-422 standard supports serial data transmission in full duplex mode between two devices. In the case of the RS-422 interface, data can travel distances of up to 1200 m. Transmission speeds of up to 2000 kbps are possible. The RS-422 interface is operated with at least two data channels: transmit (T) and receive (R).

PSI-MODEMSHDSL/SERIAL 1.5.3 RS-485 W2 The RS-485 W2 interface is similar to the RS-422 interface. The electrical levels and their logical assignment are identical to those of the RS-422 standard. In addition, the RS485 W2 interface offers the option of multipoint connections. In the case of a multipoint connection, all devices are addressed and identified via a single address. Only one device may transmit at any given moment, all other devices are in "listening mode".

PSI-MODEMSHDSL/SERIAL 3.6 Firmware update NOTE: The device must not be disconnected from the PC or the power supply during a firmware update as this can cause damage to the device. In order to benefit from a wider range of functions, you can download the latest firmware at www.phoenixcontact.net/catalog and transfer it to your device. To update the firmware, you must switch to online mode.
Optimization 4 Optimization 4.1 Optimizing the SHDSL data rate The cable length and cable cross section have a major influence on the SHDSL data rate. In turn, the SHDSL data rate influences the maximum possible serial data rate. The PSI-CONF configuration software calculates the expected SHDSL data rate from the cable length and cable diameter. The SHDSL data rate determined in this way is the basis for the maximum serial data rate.
PSI-MODEMSHDSL/SERIAL 4.2 Increasing immunity to interference If the SHDSL cables are subject to strong external sources of interference, you should further increase the immunity to interference of data transmission. This means that the lower the SHDSL data rate, the higher the immunity to interference. The lower the serial data rate, the lower the required SHDSL data rate and the more immune the system is to interference. Therefore, for your application, select the lowest possible serial data rate.
