Transparent Remote Serial Driver
The VPort 2141 provides highly customized control support for third-party serial interface devices
(other than PTZ cameras). This means that in addition to setting up a custom camera with PAN/
TILT/ ZOOM/ FOCUS commands, users may utilize this mode and introduce a customized
homepage to transmit arbitrary user-defined commands from the user side to the VPort 2141. The
third-party device connected to the serial port of the VPort 2141 will receive the same command
sent by the originator. The user only needs to attach the command in ASCII format after the special
URL. The VPort 2141 will parse the commands and translate into binary code to send out.
