MR8740/MR8741 is
not equipped with a
DHCP function.
There are two methods to install the instrument (MR8740/MR8741) to a network
using a DHCP server to assign IP addresses.
(1) Ask your network system administrator to provide an available IP address,
which is out of the range of the IP addresses the DHCP server leases, and
assign it as the static IP address to the instrument.
(2) Forward incoming traffic addressed to the IP address assigned by the
DHCP server via a router.
It is recommended to employ the former method (1) to assign the static IP
address to the instrument because the latter method (2) will make the setting
configuration complicated and require additional work to verify the IP address
assigned by the DHCP server.
As the figure below indicates, install the router between the DHCP server and
the instrument. Contact your dealer or Hioki representative for more information.
Router installation
WAN port: IP address is automatically assigned by a DHCP server.
LAN port : Static IP address needs to be manually assigned.
Set up port forwarding to forward incoming traffic to this instrument
when the router receives it from PC.

Connect the instrument to a PC with a LAN cable as follows.
1. Plug the LAN cable (100BASE-TX compliant) into the 100BASE-TX connector
on the rear of the instrument in the case of the MR8740 and on the front of the
instrument in the case of the MR8741.
2. Connect the above LAN cable to the PC. There are two ways to do this.
You can monitor and control the instrument from a PC by connecting the instru-
ment to a hub with LAN cable (100BASE-TX cable).
