The CDL MiniPlexer solves your sensor integration problems when you have more signals to transmit than available copper conductors. The MiniPlexer is a compact low power board set designed to transfer data from up to 8 separate RS232 channels over a single 115k baud data channel. For ROVs and other  applications where umbilical’s are used, this greatly increases the efficiency of data transfer, cuts down on umbilical cores needed, and reduces umbilical weight, size and cost. The MiniPlexer works by combining all the channel data into a single stream of compressed data packets. This means that the link itself does not have to run at excessive data rates and makes reliable transmission over several kilometres of copper umbilical achievable. MiniPlexer is available in an OEM format, unpackaged, and ready to be installed inside your own housing, with direct internal wiring to the card. It is also available pre-packaged. The subsea end is supplied in a housing with underwater connectors, power supplies and fuses. The surface end is supplied in a 2U rack with 9-pin d-type connectors and status LEDs for each channel. CDL sensors and instruments have an RS232 interface, and a comprehensive survey or inspection sensor package comprising CDL products can be run over a single copper data link.   Features: Up to 8 Channels RS232 inputs/outputs RS485, RS422 link Long range > 3km Selectable baud rates Very compact Low power Housed or OEM      Product Specification: Link Data Format                                                                                 RS485, RS232 Baud Rate                                                                                             9600 baud or 115kbaud Range (pre-emphasised RS 485 drivers)                                       >3km Input Data Format                                                                               RS232 Baud Rate                                                                                             9600 baud to 57.6 kbaud Transparent to both ASCII and pure binary data Will accept any combination of data, stop, parity Power Requirements: Power Input (d.c. with regulator)                                                       5-30 Vdc Power Input (d.c. without reg)                                                           5 Vdc Power Input (a.c.)                                                                                                100 - 240 Vac Current consumption (OEM)                                                             <5mA (@24Vdc typical) Current consumption (Housed including PSUs)                           Powers all attached sensors Power Supplies in Housing (with individual re-settable fuses)                                                                 Channel 1                              24V @ 4.2A                                                                 Channel 2, 3, 4                   24V @ 1.4A                                                                 Channel 5, 6, 7, 8                24V @ 1A Depth Rating: 3,000 metres (Standard)                                                                    (9,870 feet) 6,000 metres (Special)                                                                       (19,685 feet) Environment Temperature Range                                                                            Operating:            -30C to +55C                                                                                                                  Storage:                -55C to +65C Weights and Dimensions Dimensions (topsides 19" rack) Height                                                                                                    2U Depth                                                                                                    300mm Dimensions (OEM) Diameter of PCB                                                                                118mm Dimensions                                                                                          (3,000 metre housing)                                                 Length                                                   252mm (336 inc connectors)                                                 Diameter                                               140mm
