It is very rugged and can be mount- ed directly on the machine. Network segments attached together with a repeater are consid- ered separate physical networks (trunk and drop lengths for each segment are determined as if the other segments are not there), but one logical network (addresses cannot be du- plicated - the scanner and configuration tools work as a single network). The repeater does not consume an address and is invisible to all the other devices on the network. The repeater does not have an EDS file. The REP-DN can be used to extend either the Trunk or the Drop lines. It can also be used to isolate power supplies on networks with multi- ple supplies. There is no limit to the number of repeaters that can be used on one network. When a message is repeated a 2 millisecond delay is

If more than four repeaters are used in series, the inter- scan delay may need to be increased. The repeater baudrate is set via rotary switch. The baudrate on each side of the repeater must be the same. Different rates would cause the slow side to be overloaded with messages from the fast side.
