1.2.1
RS-232 connection to the PC
The AnyBus Download Adapter is set to RS232 mode as default from factory and no setting is required. This is the way the Download Adapter is normally used when connecting to a PC. If the AnyBus Download Adapter has been configured to another setting the RS232 can be set by selecting RS232 on the selection switch B1=1-2, the setting of B2 is irrelevant. Refer to Figure 1 for correct setting for RS-232. D-sub pin 2

2 Connecting the AnyBus module The AnyBus module can be equipped with several different types of application connectors. The Download Adapter is designed so it will fit all possible configurations.
2.1 Top-side application connector The AnyBus-S module can be mounted directly on the Download Adapter if the 34-pin application connector is mounted on the “top-side” or the “component side” of the AnyBus-S. Refer to the picture below. Note that it is important to connect the AnyBus module correctly to the adapter board to prevent damage.

Figure 3 Direct mounting wi th top-side application connector
2.2 Bottom-side application connector It is necessary to use the enclosed ribbon cable if the application connector is mounted on the solder-side of the AnyBus module. Note that is important to connect the AnyBus module and the ribbon cable correctly to the adapter board prevent damage.

3 Appendix A It is also possible to connect the Download Adapter serially via RS-422 and RS-485. This is described in chapter 3.1 and 3.2.
3.1 RS-422 To use AnyBus Download Adapter with RS422 you need to open the unit by disconnecting the base plate and select RS422/RS485 on the selection switch B1 = 2-3 and then select RS422 on the selection switch B2 = 1-2. RJ45 Pin 3

A standard cable for RS-422 consists of two twisted-pair connections, a signal ground and terminating resistors. The Download Adapter has built-in termination resistors on the send and the receive lines. When driving longer cables, additional terminations for the other end may also be required for acceptable signal quality. The RS-422 wiring is shown below.

3.2 RS-485 To use AnyBus Download Adapter with RS485 you need to open the unit by disconnecting the base plate and select RS422/RS485 on the selection switch B1 = 2-3 and then select RS485 on the selection switch B2 = 2-3. RJ45 Pin 5

A cable for RS-485 consists of a twisted-pair connection, a signal ground and terminating resistor. The built-in termination resistors are used as in RS-422. When using a longer cable, an additional termination in the other end may be required. The RS-485 wiring is shown below. No external connection for send/receive pairs is needed. When the Download Adapter is configured for RS-485 with the jumpers, the Download Adapter internally connects the RS-422 inputs to the RS-422 outputs to make a RS-485 bi-directional interface.
