SERVSWITCH™ DUO AND SERVSWITCH™ QUADRO
Keyboard- and PS/2 mouse-extension cabling:
6-pin mini-DIN male to 6-pin mini-
DIN male with all lines pinned straight through (1 to 1, 2 to 2, etc.). If the PC has a
5-pin DIN PC/AT style keyboard connector, you will need a PS/2 to PC/AT
keyboard adapter, 6-pin mini-DIN female to 5-pin DIN male (product code FA212).
You might be able to run keyboard- and mouse-extension cable, such as the
keyboard and mouse strands of our Premium KVM CPU Cables (product code
EHN408, see
Section 3.4.4
), as far as 100 ft. (30 m).
Cabling to CPUs’ RS-232 serial mouse ports:
You’ll need PS/2 extension cabling as
described above, plus an adapter with the pinning shown in Figure A-1 on the next
page (product code FA314), to connect the ServSwitch Duo’s/Quadro’s PS/2
mouse port to the RS-232 port on a PC.
As noted above, PS/2 extension cabling, such as the mouse strand of our
Premium KVM CPU Cables (see
Section 3.4.4
), should be no longer than 100 ft.
(30 m). If you’re using an adapter at the Duo/Quadro end instead of the PC end and
are running regular RS-232 cable, this cable should not be longer than 50 ft. (15 m).
A.3 Cabling from the Duo’s/Quadro’s COMM Port to a PC
The DB9 connector labeled “COMM” on the back of the ServSwitch Duo/Quadro is
an RS-232 port pinned according to a subset of TIA-574; see Figure A-2 on the next
page. It’s very similar to the DB9 serial ports on most PCs, except that it’s female.
You can connect a PC to it in order to do serial switching (see
Section 5.10
), back
up and restore the Duo’s/Quadro’s computer/user configuration (see
Section 5.19
), or upgrade the Duo’s/Quadro’s firmware (see
Section 5.20
). To do
this, use the DB9 male-to-female extension cable included with the Duo/Quadro.
If this cable is broken or misplaced, replacements are available separately as
product code EDN12H-MF. Specify the length you want when you order; the Duo/
Quadro can support DB9 extension cables as long as 50 ft. (15 m).
A.4 Cabling from the Duo/Quadro to a Duo Extender (Optional)
The remote user-station connector of the ServSwitch Duo’s user port #1 and the
ServSwitch Quadro’s user ports #1 and #3 is an RJ-45 jack. Run standard 4-pair
twisted-pair cabling from this connector to the matching connector on a
ServSwitch Duo Extender. (Do
not
attach these connectors to a LAN or a phone
network; you could damage the Duo/Quadro or Extender and possibly the
network as well.) This cabling can be anything from Category 3 to Category 5e, but
we recommend that you use straight Category 5 cable; it can be run farthest and
will produce the best results. Both shielded and unshielded Category 5 twisted pair
can be run as far as 200 m (655 ft.).
