Page 2: Operation
Introduction The MiniPlex-41USB is a four-channel NMEA multiplexer, enabling the connection of multiple NMEA- 0183 instruments to each other and a computer. Available are four NMEA inputs (listener-ports), two NMEA outputs (talker-ports) and one USB port for connection with a computer. Specifications: Supply voltage: from USB bus or... - Page 3 Connections NMEA Listener Ports The MiniPlex-41USB has four listener ports, ‘ In 1’ to ‘ In 4’ . Each listener port should be connected to one instrument only. These inputs are galvanically isolated from the multiplexer, as specified in the NMEA-0183 standard. Connect the ‘...

USB Port The MiniPlex-41USB can be connected directly with the USB port of a computer or a USB hub with the supplied cable. The first time the MiniPlex-41USB is connected, the computer will detect new hardware and ask for a driver disk. Insert the driver disk into the diskdrive and click OK. Follow the directions on the screen to complete the installation. -

Screenshot of MPX-Config Serial Port Before being able to configure the MiniPlex-41USB, select the COM port to which the multiplexer is connected. The virtual port created by the driver is marked with ‘ (vcp)’ . When selecting the baudrate, either choose 4800 (factory default) of choose ‘... - Page 6 NMEA Out2, the total throughput is limited by the speed of NMEA Out2, which is fixed to 4800 baud. Even when the USB port is set to 38400 baud, the throughput will be 480 characters per second, the same as on NMEA Out2. Auto mode: When Auto mode is selected, the multiplexer automatically switches between Hub- and Server mode, depending on the presence of computer generated data.
- Page 7 Indicators The MiniPlex-41USB has two LED’ s. The green LED indicates the reception of valid NMEA data on the listener ports or the USB port. The LED only blinks on valid NMEA sentences that start with a ‘ $’ or ‘ !’ and end with a LF character, thus indicating a proper connection and polarity of the connected instrument.

- Page 9 $PSMDxx Start of a proprietary command. Dictated by the NMEA standard. SMD: ShipModul manufacturer’ s mnemonic. Two- or three-character command code. For ease of manual configuration, the commands issued to the multiplexer do not require a checksum. Sentences output by the multiplexer always contain a checksum. Sentences output by the multiplexer always contain a checksum, denoted with *hh in the descriptions below.
- Page 10 CFQ – Request current configuration This sentence requests the current configuration settings from the multiplexer. $PSMDCFQ<CR><LF> The multiplexer responds with a CF sentence. OV – Overflow In case of a buffer overflow (blinking red LED on the multiplexer), an overflow sentence is output, to indicate on which input buffer the overflow occurred.
