SERVSWITCH™ WIZARD
A.3 Cabling Attached to the OPTIONS Port
The DB15 connector labeled “OPTIONS” on the back of the ServSwitch Wizard is
a proprietarily pinned port using RS-232-type signaling. You can connect any of
these devices to it:
• The Wizard’s optional Remote-Control Module (RCM, see
Section 5.2
);
• An RS-232 device for serially controlled channel switching (see
Section 5.9
);
• Another Wizard, to create a synchronized system for CPUs with multiple video
outputs (see
Section 3.3.3
); or
• A PC, in order to upgrade the Wizard’s firmware (see
Section 5.13
).
The pinout of this connector is pretty simple: Pin 9 (Signal Ground, SGND),
Pin 10 (Transmit Data, TD), and Pin 11 (Receive Data, RD) are the only pins used
for serial communication to PCs, other Wizards, and RS-232 devices. All other pins
are intended for RCM communication only and should be left unconnected;
attaching them to any other RS-232 equipment could have unpredictable and
possibly damaging effects.
The pinout for a synchronization cable is shown in Figure A-2 on the next page.
We can offer this cable as a special quote, but it’s not a stock item at the time of
this writing. The pinout for a firmware-upgrade cable (product code KV6SER) is
shown in Figure A-3.
