The 1747-DPS2 RS-232/DF1 Port Splitter by Allen-Bradley is an electronic device which divides the splintering capability of a single RS-232/DF1 Duplex communication port into 2 separate ports with a side-by-side connection capability between two external devices. It has a DC power supply with a supply rating of 100 milliAmps at 24V DC and it provides circuit voltage isolation. The 1747-DPS2 connects to a controller through the 9-pin male D-shell communication port and when a connection is established it automatically adjusts the Transfer rate (Baud rate) to 19.2 Kbps or 38.4 Kbps with respect to the controller’s baud rate and eventually matches the controller’s BCC/Cyclic Redundancy Check sum(CRC). A transmitted message initiated from the controller is received at a rate of 19.2 Kbps via the 9-pin male D-shell Network port but unlike in the 1747-DPS1, the 1747-DPS2’s D-shell port can be configured for a wider communication with a DH-485, DF1 full-duplex, or a DF1 modem network.
The 1747-DPS2 is a unique device that offers complete isolation between communication ports, and thus requires no internal isolation, and it uses it 9-pin male D-shell, PROG/HMI port with a communication rate of 19.2 Kbps for direct connection to an Allen Bradley Programming Station or HMI devices (PanelView, PanelView Plus, and VersaView). The 1747-DPS2 has an operating temperature range of 0-60 0C at a non-condensing 5-95% relative humidity range and is designated T5 North America temperature code. It weighs 168g (0.37lb) and has dimensions of 101mm x 35mm x 70mm (3.98in x 1.38in x 2.75in).
