2.5 RS232 CONNECTIONS
The Chameleon256 Routing Switcher can be controlled by its optional front
panel keypad controller, by Knox remote controllers, or by external RS232 devices
via the three 9-pin connectors on the rear panel. To use an external driver connect
a source of RS232 serial data to one or more of the three DB9 connectors marked P1,
P2, and P3. The Chameleon256 Routing Switchers are wired as data terminals; that
is, data out of the Chameleon256 is on pin 2, data in is on pin 3, and pin 5 is ground
(common).
A direct connection (pin-to-pin) from a PC-compatible serial port normally
works well; select 9600 baud, 8 bits, no parity, one or two stop bits, and no flow
control, for best compatibility.
When a second chassis (usually audio) is to be linked to the first (usually
video) it is customary to connect the controller to one of the top two RS232 input
connectors (P1 or P2) on the first chassis, wired normally. Then connect a cable
from the bottom input connector (P3) on the first chassis to one of the top two
input connectors on the second chassis wired as follows: first chassis pin 2 to
second chassis pin 3, pin 5 on the first to pin 5 on the second. A third chassis
should be connected to the bottom connector (P3) of the second chassis.
2.6 INITIALIZING THE FRONT PANEL CONTROLLER
On power-up, the front-panel LCD display will indicate which Knox routing
switcher the Keypad Controller has been set up to operate. The Chameleon256
uses the Cham256 setting. If the controller is not set for the Chameleon256, push
the STORE key, then 93. The display will prompt you for the type of routing switcher
you are controlling. Enter 5 for the Chameleon256, then push ENTER (use 1 for the
RS4x4, 2 for the RS8x8, 3 for the RS16x16, or 4 for the Chameleon64).
If the front panel controller is being used for the first time, or in the event of a
complete memory loss, there will be nonsense characters in the current crosspoint
pattern map. To reinitialize these patterns, push the STORE key, then 94. Enter 1
then push the ENTER key to reinitialize, or push 0 and ENTER to quit.
CAUTION -- reinitializing erases all of your stored patterns!
