NTI SERIMUX SERIES CONSOLE SWITCH
2
• Number of ports: 9, 17, 25 or 33 RS232 ports;
• Connectors: RJ45 male
• Data: asynchronous, 5, 6, 7, or 8 bits per character,
• Parity: even, odd, or none
• Stop Bits: 1, 1 , 2, or 2 bits
• Flow Control: Xon/Xoff, RTS/CTS, Both, or None
• Baud Rate: 50 bps to 128,000 bps
device equipment that can transmit and/or receive data using RS232 interface
inactivity when a port is not receiving data from the device connected to it
terminal program a terminal emulation program- computer program that communicates via RS232 interface
(i.e. HyperTerminal)
"dumb" terminal Serial terminal device or CPU terminal program that emulates a serial terminal
timeout time period of inactivity after which a port will be disconnected (the inter-port connection will be broken)
Baud rate serial device or port receiver and transmitter speed; measured in "bps" (bits per second)
Flow control a method to temporarily stop and restart serial data transfer (flow). It can be
- Hardware (out-band)- usually using the RTS and CTS physical handshaking signals;
- Software (in-band)- using special characters, usually named Xon and Xoff, inserted
in data being transferred;
- Both
Disconnect sequence 1 or 3 char sequence inserted in the serial data flow, to disconnect the user from the
attached serial device and to return to the initial user menu.
