16- OR 32-PORT 10/100 PHYSICAL LAYER ETHERNET SWITCH
7. Serial Port/LAN Port Commands
The switch may be controlled using simple ASCII character strings via the RS-232
interface or via the Ethernet TCP/IP LAN port.
7.1 Serial Port
The following information provides the parameters necessary to control the switch
using any standard serial interface:
a) Baud rate internally selected for 9600 (factory default) or 19,200 baud.
b) Transmit and receive set for 8 data bits, 1 stop bit, no parity.
Set parameters would look like this:
MODE COM
x
9600,N,8,1
7.2 LAN Port
When communicating with the switch using TCP/IP via the LAN port, you must
specify port number 3001 (as well as the IP address) when establishing the TCP/IP
connection. Some versions of HyperTerminal allow connections to IP addresses.
You may also use Telnet to send command strings to the switch (but remember to
specify 3001 as the port number). The command strings are the same regardless of
whether you are communicating via a serial port or via the LAN port.
The sequence for communicating with the switch is defined as:
a. Start sequence:
ASCII “cr”,“
/
”, “
/
” (hex 0d, 2f, 2f)
