. SETTING PINS AND CHECK PINS
Check pins in “CHCN”
Signals of 90, 0, T1, 0V, 5V,
and PZ can be observed in this
check pins.
The location is shown below.
90 T1 5V
00VPZ
90:
Differentially amlified signal
from B and XB input signals.
0:
Differentially amplified signal
from A and XA input signals.
T1:
2.5V DC (=1/2 Vcc)
0V:
Signal ground
5V:
Power source
PZ:
Comparated digital signal
from Z and XZ input signals
.
Check pins “CHCN” is added
on PCB version 06D or later.
Location of check pins is displayed.
Setting pin “SW1”
“A” setting:
CMAL function, by checking
position data and reference
signal, is valid.
“B” setting
Above function is invalid.
Setting pin “SW2”
“A” setting:
For analog reference signal
input.
“B” setting
For digital reference signal
input.
Setting pin “SW2” is added
on PCB version 06D or later.
