CE-l29P

NOTES:

Some of tape recorders may not operate properly owing
to different

specification or electrical characteristies

affected by signal distortion, electrical noise, level drop-
out caused after long years of use.

• When using the tape recorder fitted with the mixing

feature, it needs to disable the mixing function for both
recording and playback_

Oepending on the

tape

recorder used, better reading

result may be attained when the red plug is unplugged
from the MIC [ack,

As it may impede proper data transfer and verification
depending on the position of the volume control, tone

control, bass control, and treble control, try to find the

optlrnum

level by varying their positions.

4. CIRCUIT DESCRIPTION

The CE-129P has two microprocessors; the P-CPU (inside

of CE-129P) by with data transfer is carried out with the
host CPU (M-CPU: inside of computer) and the prlnter

control PCU.

I

M-CPU to P-CPU data transfer method

Since there are no SEl1 and SEl2 used for the PC-1401
and

El5500,

OEVICE SElECT

is dependent on the

contents of data.

(UEVICE

SELECTJ

DOUT

(11

For OEVICE SElECT, XOUT becomes high.

(2) As the P-CPU receives a high state of XOUT, it sends

ACK to the M-CPU.

(3) As the M-CPUreceives ACK, it sends back BUSY.
(4) Oata is received to the P-CPU with a high state of

BUSY. ACl,

REMOTE ON, CPU select actions is

carried out depending on the contents of data.

(1) XOUT goes low when the print data is transferred.
(2) BUSY from the M-CPUturns high level.

(3) Upon receipt of BUSY, ACK of the P-CPU is set high

and the data is received to the P-CPU.

Since the data is transferred in bit by bit serial mode, above
steps (2) and (3) are repeated eight times to complete
transfer of one data, For instance, those steps are repeated
for 192 times (24 x 8) in order to transfer a 24 digits data.

The print commands, however, is sent out to the P-CPU at

the end of the data in a form of the code "00".
