... ESD. The surge suppression on all signals prevents damage caused by lightning or high voltage. 3.2 Power Supply The ES-R-2001B-M and ES-R-2101B-M accept a wide range of supply voltages, from 48V DC. The power input connector is a 3–pin terminal-block style connector as shown in Figure 1 below. An external switch-mode power adapter is supplied with the converter. Figure 1 3 ...

... Before applying the termination, check your cable specification for proper impedance matching. Termination is normally used in the node at each end of the bus, but nodes in the middle of the bus should not have termination enabled. The ES-R-2x01B-M converters have jumpers to allow internal termination resistors to be enabled if required ...
