This operation mode supports up to 5 simultaneous connections, so that multiple hosts can collect data from the
same serial device at the same time.
Service Mode : Virtual COM Mode
This option enables the Serial Port in the Converter to act and be controlled as PC’s COM port for Windows.
One PC can have as many as COM ports on the network without the limitation of PC’s physical slots. The
Virtual COM ports on the network can also be shared by multiple hosts.
Service Mode : TCP Client Mode
When Serial to Wi-Fi converter is configured as TCP Client, it allows the connected serial device to initiate the
TCP connection to remote host software when needed. When connected, the data is transmitted bi-directionally
and till the data transmission is finished, the TCP connection will be closed by TCP Client. The connect-on-
demand TCP Client operation helps the host computer to manage high number of remote devices that exceeds
the maximum simultaneous TCP connections allowed. Serial to Wi-Fi converter supports up to 5 simultaneous
TCP Client connections for redundant system considerations
Notification
Port status can be notified to administrator by email, SNMP trap, or System Log.
Several events of notification include :
DCD changed: When DCD (Data Carrier Detect) signal changes, indicating the modem connection status has
changed, the event will be triggered.
RI changed: When RI (Ring Indicator) signal changes, indicating the incoming of a call, the event will be
triggered.
DSR changed: When DSR (Data Set Ready) signal changes, indicating that the data communication equipment
is powered off, the event will be triggered.
CTS changed: When CTS (Clear To Send) signal changes, indicating that the transmission between computer
and DCE can proceed.
Port connected: In TCP Server Mode, when the device accepts an incoming TCP connection, this event will be
trigger. In TCP Client Mode, when the device has connected to the remote host, this event will be trigger. In
Virtual COM Mode, when Virtual COM is ready to use, this event will be trigger.
Port disconnected: In TCP Server/Client Mode, when the device looses the TCP link, this event will be trigger.
In Virtual COM Mode, When Virtual COM is not available, this event will be trigger.
To enable activate the notification, specify the event type and the notification methods.
The details of SNMP trap Server, Email SMTP server, or Log server IP should be configured first properly in
device “Configuration” “Management”.
VCOM List
You can monitor the COM port status from the “VCOM” function. The monitored items can also be defined by
the “Select Monitor Items” icon. The COM ports must be configured first before monitoring the status.
DSTool offers 5 Setup Wizards to help you manage Serial Wi-Fi Converter devices as a group.
