VS-311H - Connecting the VS-311H 11
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
Method B ( Figure 6 )
—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem
adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually
contains all nine wires for a full connection of the D-sub connector. Because the
null-modem adapter (which already includes the flow control jumpering described
in Method A above) only requires pins 2, 3 and 5 to be connected, you are free to
decide whether to connect only these 3 pins or all 9 pins.

4.5 Controlling via ETHERNET
You can connect the VS-311H via the Ethernet, using a crossover cable (see
Section 4.5.1 ) for direct connection to the PC or a straight-through cable (see
Section 4.5.2 ) for connection via a network hub or network router.
After connecting the Ethernet port, you have to install and configure your Ethernet Port. For
detailed instructions, see the “Ethernet Configuration (FC-11) guide.pdf” file in the technical
support section on our Web site: http://www.kramerelectronics.com
4.5.1 Connecting the ETHERNET Port directly to a PC (Crossover
Cable)
You can connect the Ethernet port of the VS-311H to the Ethernet port on your PC,
via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identifying the VS-311H
with the factory configured default IP address
