Irda & Ask Diagnostics - Sharp UP-3300 Service Manual

When checking with two or more satellite machines connected,
enter the terminal No. (000 ∼ 015) and press the ENTER key
for each satellite connected. To execute, press the ENTER key
without entering the terminal No. The display is as shown
below. Do not use the same terminal No. for different machines
(master/satellite).
Data Transmission Check (Master)
Input Master Terminal Number
Input Satellite Terminal Number : xxx
xxx xxx xxx xxx xxx
Data Sequence Number
With the above setting, data transmission between the master
machine and the satellite machine is started.
2 Check content
•
Data in the following format composed of 2byte sequence No.
and 254byte AAH data are transmitted from the master
machine to the satellite machine. The master machine displays
the sequence No.
Test data format (1 packet = 256byte)
1 2 3 4 5
XX XX AA AA AA
XXXX : Sequence No. (2byte: 4digits of binary decimal numbers)
AA : Transmission data (AAH) x 254 bytes
•
The satellite machine sends back the received data to the
master machine. The satellite machine displays the received
sequence No.
•
The master machine receives the data, and checks the se-
quence No. and 256byte AAH data. In case of an error, the
master machine displays an error code and terminates the
check. If two or more satellite machines are used, the above
operation is repeated. If data transmission with all the satellite
machines are normally completed, the master machine incre-
ments the sequence No.
The above operation is repeated.

01 Command abnormality (except for during transmission)
02 No data received.
03 Received data present.
Received data remained.
04 Remote station not ready (in sending)
"NTDY" is sent back because the remote station is not ready
for reception.
05 Reception buffer full (in sending)
The controller reception buffer of the remote machine is full.
06 Resend error (in sending)
Retry over (5 times) when no response
07 Collision error (in sending)
When an collision occurred in data transmission, retry over
(16 times) at re-collision after a random time (0 ∼ 255ms).
08 Line busy time out
Transmission cannot be made by multi-station
communication to cause time out in data send wait time.
09 Reception size over (in receiving)
The reception buffer size is insufficient.
0A Hardware error
Interface abnormality (No SRN interface or abnormality in
SRN controller)
Press the Touch panel to terminate the check.
