Intruduction The MD-45 is used to convert between RS-422/485 and RS-232/V.24 signals.This device is often used in multidrop applications connected to a PC or PLC. In 2-wire half duplex applications (RS-485) the direction of the bus can be controlled by data which means that the converter turns the bus depending on the data sent on the bus. This makes it possible to use the unit with equipment that has no handshaking signals.The maximum transmission rate possible is 115.2 kbit/s. 1234 R+ R- T+ T- 56789 T+ T- R+ R- CHANNEL 3 CHANNEL 4 LD-01 DC PWR RD TD DCD2 DCD3 DCD4 CHANNEL 2 POWER 123456789 R+ R- T+ T- T+ T- R+ R- CHANNEL 3 CHANNEL 4 LD-01 DC PWR RD TD DCD2 DCD3 DCD4 CHANNEL 2 POWER 123456789 R+ R- T+ T- T+ T- R+ R- CHANNEL 3 LD-01 DC PWR RD TD DCD2 DCD3 DCD4 CHANNEL 2 POWER 6157-2213 3 https://manual-hub.com/ 2.

Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap), before the lid on top of the modem is removed. ! W arning! Do not open connected equipment. Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections. NOTE! The change of DIP-switch settings are valid only after a power on. If configured by any other method during normal operation, this new configuration override the DIP-switch settings. However, after a new power on the DIP-switch settings have precedence. 6157-2213 https://manual-hub.com/ 11 Selection of data rate ON S1 1 2 34 56 78 Data rate 1 200 Turning time 780 µs ON S1 1 2 34 56 78 2 400 410 µs ON S1 1 2 34 56 78 4 800 220 µs ON S1 1 2 34 56 78 9 600 130 µs ON S1 1 2 34 56 78 19 200 48 µs ON S1 1 2 34 56 78 38 400 34 µs ON S1 1 2 34 56 78 57 600 22 µs ON S1 1 2 34 56 78 115 200 11 µs Data or RTS-control ON S1 Data control 1 2 34 56 78 ON S1 RTS-control 1 2 34 56 78 ON S1 Transmitter 1 2 3 4 5 6 7 8 always active Factory settings ON S1 1 2 34 56 78 ON S2 1234 S1: 8 not used 12 Selection of bits ON S1 9 1 2 34 56 78 ON S1 10 1 2 34 56 78 ON S1 11 1 2 34 56 78 ON S1 12 1 2 34 56 78 2/4-wire transmission ON S1 2-wire 1 2 34 56 78 ON S1 1 2 34 56 78 4-wire Termination with fail-safe * ON S2 Terminated (4-wire) 1234 ON S2 Terminated (2-wire) 1234 ON S2 No termination 1234 * The fail-safe function forces the signal state of the receiver to OFF when the connected transmitter is in tri-state (transmitter inactive).

If there is more data on TD before the turning time is ended the transmitter stays active for additional one character. In RTS-control mode the transmitter is activated by the RTS-signal. In this mode the switches for data rate and number of bits has no effect.The LED indicators is controlled by the data signals.The active termination secures that the signal level at the receiver is in off-state (>0.2 Volts) when there is no data transmission. Full duplex is only possible if RS-422 is used. 7.1 Block diagram V.24/RS-232 3 TD 7 RTS 8 CTS TD LED RTS LED CTS LED 6 DSR RD 2 5 SG +5V RD LED MCU S1:6 0VA +5VA 0VA V.11/RS-422 RS-485 3A 4B S2:4 S2:3 +5VB Bus termination 0VB +5VB Bus termination 0VB S2:2 S2:1 1 A' 2 B' 0VB 5 Shield Power F1 Insulated power supply supply +5VB 0VB 6157-2213 https://manual-hub.com/ 13 7.2 Line connection 4-wire MD-45 1 Receiver A' 2 B' 3 Transmitter A 4 B Shield *) 5 Twisted pairs RS-422/485 equipment 2-wire MD-45 RS-422/485 equipment A Transmitter B A' Receiver B' Twisted pairs 3 Transmitter/ A/A' Receiver 4 B/B' A/A' Transmitter/ B/B' Receiver Shield *) 5 *) If shielded cable is used, connect the shield only at one end to avoid ground currents. 7.3 H ints RS-422/485 was designed for multidrop applications. When a system is installed it should form a bus structure (see diagrams). Star shaped networks should never be created, there are other Westermo products designed to work in star net applications. To get a correct installation according to the RS-422/485 specification it´s very important that the line is terminated at the correct points. The recommendation is to terminate the receiver on the master unit and the final bus slave unit. See diagrams for details of how this is done with RS-485 (2-wire) and RS-422 (4-wire). The line transmitter used in the MD-45 is activated by data received on the RS-232 interface, unlike conventional converters that rely on a control signal (e.g. RTS). If any problems do occur on set up of the MD-45, the LED's will be helpful. · PWR: · RD: · CTS: · RTS: · TD: The unit has power. Data received on the RS-422/485 interface. Follows RTS.
