- 54 -
Jumper Wire Settings
S1, S2 : These enable/disable HOLD (Pin 6). HOLD is active High, so the jumper wire should be connected to
S2 (HOLD = low) for normal use. When using HOLD, connect the jumper wire to S1 (HOLD = High).
(For the initial setting, the jumper wire is connected to S2.)
S3, S4 : These enable/disable TLOAD (Pin 13). Connect the jumper wire to S4 (TLOAD = High) for normal use.
When using TLOAD, connect the jumper wire to S3 (TLOAD = Low). (For the initial setting, the jumper
wire is connected to S4.)
S5, S6 : These enable/disable CS (Pin 14). Connect the jumper wire to S6 (CS = High) for normal use. When
using Power Save, connect the jumper wire to S5 (CS = Low). (For the initial setting, the jumper wire
is connected to S6.)
Supplied Program
This PWB has a control program that facilitates evaluation of the CXA3266Q. Operation methods and
precautions are as follows.
1. Compatible personal computers
Use an IBM PC/AT or compatible machine equipped with a 25-pin D-SUB parallel port (printer port). Also,
operating systems which support the program are MS-DOS 5.0 or newer and MS-Windows 3.1 or newer.
(When using Windows, start the program from the DOS window.)
2. Connection of the supplied cable
Connect the supplied cable to the parallel port of the personal computer and the DBUS1 connector of the
CXA3266Q-PWB.
3. Connect the power cable and supply power to the CXA3266Q-PWB.
4. Start the program
(1) Boot the personal computer and then shift to the directory containing the program.
(2) Set MS-DOS to US mode.
→ US Return or Enter
(3) Input the program name.
→ CXA3266Q Return or Enter → Move to the program screen.
