Using E5810 Web Access
Viewing and Modifying Configuration
Password
[E5810]
E5810 configuration and instrument control pages are password-
protected against changes. To change from the default password
(or any password) to a new one, enter the current (old) password in the
Configured Value
column and enter the new password in both boxes in
the
Edit Configuration
column of the
Configuring your E5810 LAN/GPIB
Gateway
page. The password is limited to 8 characters. The default
password is "E5810".
You do not need to use a password for SICL or VISA programs with the
E5810 interface. This password will not prevent unauthorized personnel
from using your E5810, but it will prevent them from easily modifying its
setup or controlling instruments attached to it. If additional security is
desired, an isolated subnet is recommended.
RS-232 Baud Rate
[9600]
Number of bits per second that are transmitted. Available baud rates for
the E5810 are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and
115200. The RS-232 baud rate is the speed of data transmission and
reception on the RS-232 interface. The baud rate value is dependent on
the peripheral device you connect to the RS-232 port. Check the
documentation for your peripheral device to set this value.
RS-232 Bits
[8] The number of bits that comprise a byte of data. Available number of bits
options are 5, 6, 7, or 8. This is the number of data bits in a character
frame in RS-232 serial data transmission. The value is dependent on
the peripheral device you connect to the RS-232 port. Check the
documentation for your peripheral device to set this value. Available
number of bits options for the E5810 are 5, 6, 7, or 8.
RS-232 Flow
Control
[NONE] Flow control is the protocol used to pace data transmission over the
RS-232 serial connection. The flow control value is dependent on the
peripheral device you connect to the RS-232 port. Check the
documentation for your peripheral device to set this value. Available flow
control mechanisms for the E5810 are NONE, XON/XOFF, RTS/CTS,
and DTR/DSR.
