[ 26 ] Ethernet Test
[Function]
Tests the Ethernet counter communication.
QT-6600 in the reception mode becomes on standby and, then, QT-6600 in the transmitting mode
sends data.
Once the communication opens properly, the number of successful/failed communication to LCD
is displayed on the counter, which will be printed out when the test ends.
* Ethernet does not operate without setting a MAC address. Be sure to set a unique MAC address
before use.
* When testing the Ethernet counter communication without a HUB, the AutoNagotiation function
is disabled. Set the baud rate at 100base to run a test.
* If an Ethernet printer test has been performed beforehand, run all operations stating from INIT
boot-up.
< Transmitting/receiving data >
Test counter: counts up from 1 through INT Max. and returns to 1.
The test data length (CNT + DATA) is 1446 bytes in total, excluding the Ethernet header, the IP
header, the TP header, etc.
<TCP Mode>
A counter communication test by TCP protocol with an error control.
When the receiving end (command below a=2) receives the data properly, the data is checked
and returned (FBh – 01h, 00h, FFh-00h) to the transmitting end, which checks the data returned
(repeats the operations).
[Operation]
When an ID is set, perform the test with that ID. When you change the ID, run all operations
starting from INIT boot-up. The same applies to the baud rate.
Operation : b m 0 a 5 1 ST
b: Baud rate
0 Any number except for 1 (or not specified) → AutoNegotiation
1 100BASE
m: ID
<ID>
1 through 9 are valid numbers for the ID. If an invalid value is assigned, number 1 is automatically
set and IDs are converted as shown in the example below.
The upper values of the IP address are fixed at 192.168.0 and the lowest number corresponds to
the ID.
e.g. ID=1 → IP address = 192.168.0.1, ID=9 →IP address = 192.168.0.9
Note that the address is 192.168.0.10 in the receiving mode regardless of the ID. In the
transmitting mode, the data is sent to a fixed address of 192.168.0.10.
