Connecting the EMU

This section describes the procedure for connecting the EMU to the host system. It is possible to have up to eight EMUs connected together in a daisy chain configuration. The first EMU on the chain must be connected to the host system using the serial RS232 cable provided. The EMU ID for the first shelf in the chain must be set as ID 0 so that the system will see it as the master. All other EMUs connected on the chain will be seen by the system as slaves.

The EMUs should be daisy chained together using the EMU cable provided (3 connectors). The top connector of the EMU cable should be attached to the 3-pin connector on the EMU. The middle connector of the EMU cable should be connected to the next shelf on the chain.

To the bottom connector on the EMU cable connect the second EMU cable provided. Connect the middle connector of the second EMU cable to the third EMU on the chain. Continue this procedure until all the EMUs (up to a max. of 8) have been connected together.

Figure 3-5 shows how to connect the EMUs together.
