Black Box SW723A-R4 ユーザーズマニュアル

If a CPU’s keyboard port is PC/AT compatible, its mouse port is an RS-232
serial type, and its video port is a VGA, SVGA, XGA, or compatible type with an
HD15 connector, first choose your CPU Adapter Cable:

• If your video resolution is not higher than 1024 x 768 pixels, and if the

CPU is within 20 ft. (6.1 m) of the Switch, you can use the standard (non-
coaxial) cable with the product code EHN048.

• If your video resolution is higher than 1024 x 768, or if the CPU is farther

than 20 ft. (6.1 m) from the Switch, you should use the coaxial cable with
the product code EHN282, including the adapters that come with it.

If you use the EHN048, hook it up to the ServSwitch and the CPU this way, as
shown in Figure 8 on the next page:

• Plug the cable’s DB25 

connector into one of the Switch’s numbered

CPU ports.

• Plug the cable’s DB9 

connector into the CPU’s mouse port.

• Plug the cable’s 5-pin DIN

connector into the CPU’s keyboard port.

• Plug the cable’s HD15 

connector into the CPU’s video port.

If you use the EHN282, hook it up to the ServSwitch and the CPU this way, as
shown in Figure 9 on the next page:

• Plug the cable’s DB25 

connector into one of the Switch’s numbered

CPU ports.

• Plug the cable’s 6-pin mini-DIN

connector with the “MOUSE” label on

it into the 6-pin mini-DIN end of the included mouse adapter. Then plug
the DB9 end of the adapter into the CPU’s mouse port.

• Plug the cable’s unlabeled 6-pin mini-DIN

connector into the 6-pin

mini-DIN end of the included keyboard adapter. Then plug the 5-pin DIN
end of the adapter into the CPU’s keyboard port.

• Plug the cable’s HD15 

connector into the CPU’s video port.
