6.1 FAQs
Q1
. What is meant by “5 x redundant hosts”? Does it mean 5 x serial port device?
A1
. “5 x redundant host” mean the maximum number of connections is 5 redundant host PCs connect via
Ethernet to the SDS device, with 5 redundant host PCs (VCOM, TCP server, TCP client; or 4 redundant host PCs in
UDP mode.
Q2
. Can you explain the "Auto Scan" button?
A2
. When you click the “Auto Scan” button, the system will automatically scan ports 4000 to 65535, and check
which port is free. For example, if port 4000 is free, the control port number will be set to 4001.
Q3
. What is the UDP mode used for?
A3
. UDP mode is different from TCP mode; UDP does not need to establish connection for data transmission.
A UDP listening port is just for receiving data from the network. If you send data to a UDP listening port, it is used
for receiving. If you want to send data to a destination host, you can write data to the serial port, and the data
will be sent to the destination host and port.
Q4
. What is the "Disconnect" button used for?
A4
. The Disconnect button lets you manually disconnect the TCP client connection from the TCP Server.
Q5
. On initial install I get an “unsigned driver” message. What does it mean and is it OK to proceed?
A5
. When you connect a new hardware device to your computer, Windows tries to find and install a software
driver for the device. You may see a notification that a driver is unsigned.
►
Windows will alert you with a message if a driver is unsigned, was signed by a publisher that hasn't verified its
identity with a certification authority, or has been altered since it was signed and released. For example, the
message
Windows requires a digitally signed driver
displays if a driver lacks a valid digital signature, or was
altered after it was signed, can't be installed on 64-bit Windows.
