What is USB MultiPort?

USB is a complex word of “Universal”, meaning all peripheral devices use the same connector,

and “Serial”, meaning devices are connected as a daisy chain through serial transmission. USB

is an interface suggesting a solution to inconvenience and inefficiency caused by slow speed and limited device connection of existing external ports(serial or parallel). Compared to external ports that were only used to connect devices such as modems, printers and scanners, USB is powerful in that it connects all types of basic peripheral devices that were each connected via different types. Also, when a new device is plugged, it’s auto-detected without any rebooting or setup process, enabling 127 connections maximum. Installation is handy since PnP is perfectly supported. No extra equipment is needed since most of the main-board chipsets include the USB controller. USB cable type supported is type A, which can utilize the USB port of the PC or the USB hub. This product obtains power from USB, and this makes the product powerful since no external power supply is required.

Multi-4U/8U under V1.5

Multi-4U/8U under V1.5 can work with USB power only, so does not need external adapter. It can supply +5V or +12V when the device needs. This feature is useful when small devices such as cash box, bar-code reader and printer are connected to PC POS system. +5V or +12V

adapter don’t affect the operation of USB MultiPort because this part is separated from serial

communication part. This voltage is supplied through 9th pin of DB9 connector.

 Event on Surprise Removal  : The Event On Surprise Removal option is generally left unselected. If an application

sets SERIAL_EV_EVENT2 (refer Windows DDK) in it is event bitmask and this feature is enabled, the device driver will signal this event on surprise removal.

 Set RTS on Close: Selecting the Set RTS on Close option will set the RTS signal on

closing the port.

 Disable Modem Control at Startup: This option is used to control the modem control

signals DTR and RTS at startup. In normal operation, the modem control signals at startup follow the behavior of the legacy port. However, due to timing differences between a legacy COM port and a virtual COM port, a "spike" on one of these signals in the legacy port can appear as an assertion of the signal in the virtual COM port.

 Devices that monitor these signals can enter the wrong state after an unplug-replug

cycle on USB. Note that if \ the "Serial Enumerator" option in the property page is selected, then the enumeration sequence causes the modem control signals to change at startup. So if it is necessary to select "Disable Modem Ctrl At Startup", then it is likely that "Serial Enumerator" should be unchecked in the property page.

 Don’t adjust these parameters if you can use the device normally. If not, please
