Rack-type serial device servers USR-N668
Serial port switching among RS232/RS485/RS422
New and industrial design which saves the port space of device, prevent from ash and collision and promote the safety while operating.
Works at RS232 port by default. Please adjust the dial code to corresponding position when you use RS485/422 serial port.
Every serial port can choose mode freely, don't worry about unified mode for all serial ports.
Interfaces of serial device servers USR-N668
8 serial ports
Hardware protection
EFT:Electrical fast pulse train
Ensure that the equipment hardware is not damaged
when the instantaneous large current (such as lightning
strike, power switch, etc.) occurs in the circuit
Power-4KV
net port-2KV
Electrostatic protection ESD
Prevent electrostatic damage to equipment
( ex body static electricity, dust static electricity,
(such as lightning strike, power switch, etc.)
electric power application environmental arc）
Air: ±15KV
Contact: ±8KV
Watchdog
Hardware watchdog design,
never crash in 24 hours
Work mode
TCP Server
Serial server devices USR-N668 listen on the setting port and wait for a TCP client connection.
The data which the serial ports sent out transparently transmit to all connected client via serial device USR-N668.
TCP client mode
Serial device servers USR-N668 initiate a TCP lint to the set IP address. If the connection fails, N668 will keep
trying to reconnect until it succeeds. Once the link is successful, the data will be transparently transmitted
between PC and serial device in bi-directional.
UDP mode
Serial server devices USR-N668 sent the data to designated IP /Port. If the connection fails,
USR-N668 will keep trying to reconnect until it succeeds. Meanwhile, USR-N668 listen the port and forward
all data received to serial device.
httpsD Client
Support serial data transmitted to designed server in httpsD way
Special function
The clock to proofread
RTC(real-time clock, no network required)+NTP(net time)
It can still provide accurate time positioning for the system
whether in the networking environment or not
More Function
VPN+Diagnosis of network + Timing task +DDNS+Modbus TCP to RTU
Remote monitoring and remote firmware upgrade
Remote monitoring can check the running status of field equipment
