[ 17 ] RS232C PORT batch test
[Function]
  This is the RS232C port batch test.
  The loop back test for RS232C port is performed by making the connection shown in the figure.
  The  loop  back  test  is  performed  from  COM1  to  COM  3  by  the  following  setting  by  one  time 
check.
  When performing this test, fix loop back connectors to all COM ports.

[ 18 ] Ethernet test
[Function]
  This test will check the counter-communication of Ethernet.
  Always make the receive ECR in the wait mode first and then send data from the send ECR.
  The counter of the number of successful/failed communication to the LCD is displayed after the 
communication normally starts. It is printed after the test.
 NOTE:  Please  use  the  Hub  or  the  crossing  cable  for  connection  between  the  receive  ECR  and 
the send ECR. 
* Send/receive data
[LCD]
[PRINT]
1. TCP mode
  Counter-communication test by the TCP protocol with error control
2. UDP mode
  Counter-communication test by the UDP protocol without error control
  In  both  TCP  and  UDP  modes,  when  the  receive  ECR  (a=2  below)  receives  the  data  normally, 
the  test  checks  the  received  data,  reverses  the  received  data  (FBh  -10h,  00h,  FFh-00h),  and 
sends  back  the  data  to  the  send  ECR  (a=1).    The  send  ECR  checks  the  reversed  data  (The 
same repeats hereinafter).
  Also, when the receive ECR (a=4) receives the data normally, the test checks only the received 
data. 
  The  send  ECR  (a=3)  waits  for  one  second  and  starts  sending  data  again  (the  same  repeats 
hereinafter).
[Operation]
*   Once an ID is set, make sure to perform the test using this ID. When changing the ID.
 m  0  a  5  1  ST
m: Own ID (as for the designated ID, refer to "About ID")
a:  1 → TCP send mode  2 → TCP receive mode  3 → UDP send mode
  4 → UDP receive mode
   Continue the test unless an error occurs.
  End the test manually by pressing [ESC] (end the send ECR first.).
* About ID
ID is effective in the range from 1 through 9. A value which is not in this effective range will 
be changed to 1, and converted as follows.
The upper part of the IP address is fixed as "192.168.0", and the last address is the ID.
Example: ID=1 → IP address = 192.168.0.1,  ID=9 → IP address = 192.168.0.9
The ID is always 192.168.1.10 in the receive mode. The send mode sends data to this fixed 
192.168.0.10.
← Mode display ("UDP MODE" appears for UDP mode)
*  In both TCP and UDP modes, the number of successful/failed communication is displayed. 
    Each success counts up the success counter, while each failure counts up the failure counter.
← Mode display ("UDP MODE" appears for UDP mode)
← Prints the number of successful and failed communication 
upon the end of the test

[ 19 ] MAC (Media Access Control) Address SET
[Function]
  This test will write the MAC address.
[Operation]
*   Once  an  ID  is  set,  make  sure  to  perform  the  test  using  this  ID.  When  changing  the  ID,  turn  the 
power on again.

x : Writing the address
1 : Writes the address by manually writing the MAC address
In the manual input mode, the test enters the wait mode for the input of MAC address.
The address can be inputted in 8 bit. Inputting three-digit decimal and the [ST] key deter-
mines 8 bits. Performing this operation for 48 bits (6 times) inputs a 48-bit address, and 
the sixth input of [ST] writes the address. The address inputted in the number display 
position in 8 bit is then displayed in hexadecimal. The inputted address is cleared by the 
input of [CLEAR]. The test ends without writing an address by the input of [ESC]. 
* when writing MAC address "FF8048FF9800"
After entering the manual writing mode, the above address can be written by the input 
of the following: numbers "255" + [ST] → "128" + [ST] → "072" + [ST] → "255" + [ST] 
→ "152" + [ST] → "000" + [ST] .
NOTE: When you replace the EEPROM(IC35) with new one, please input the MAC address to the 
new EEPROM by using this test.
  The MAC address is described on the Main PCB.

[ 22 ] Drawer open test
[Function]
  This test will check the drawer open function. The test ends by the judgment of the operator ei-
ther by OK or NG only when the one time check is selected.
[Operation]
  Operation :   x  n  0  9  1  ST
x:  0 = All drawers open (can be omitted), 1 = Drawer 1 open, 2 = Drawer 2 open
n:  0 = One time check (can be omitted)
  not 0 = Continuous check (To stop the test, press "ESC" key)
* When the continuous check is selected, the drawer opens every 2 seconds.
* The following "OK" or "NG" key can be used in case of one time check.
  "OK" = 1, "NG" = 9
[LCD]
  The status signal from the drawers appears in the status display position of the LCD.
  In  case  of  continuous  check  as  well  as  when  all  drawers  are  open,  the  status  appears  after  all 
the drawers open.

[ 24 ] OBR test
[Function]
  This  is  a  scanner  test.  The  test  enters  the  wait  mode  for  the  scanner  input,  and  waits  only  for 
scanner.
  The  test  determines  the  result  between  OK  and  NG  by  comparing  the  fixed  data  and  the  read 
data.
  Make sure to connect OBR (HHS-15) to COM 2.
  * The fixed barcode is as follows.

[ 25 ] MCR test
[Function]
  This is a card reader (MCR) test. The test enters the wait mode for only MCR input.
  The  test  judges  the  result  between  OK  and  NG  by  the  comparison  between  already  set  data 
and read data. 
[Operation]
