ER-04RP
11. Test function (SWI-7: ON)
To execute the test function, first turn power off, set the switch SW1-7
to ON, and then turn power on. The operation initiates the execution
of the test as set by SW1-2, SWI -3, and SW1-4.
11-1. ROM/RAM test (SW1-2:ON,
SWI-3:ON,
SW-I -4:ON)
A sum check of the ROM and a read-after-write test on a particular
area of the RAM are performed.
The RAM is tested with respect to the comman~data buffer area.
80H bit shift pattern is used as the write data.
(8oH + 40H + 20H ...... OIH + 80H)
After the test is mmpleted, the following printout is produc~.
The sum data and the version of the ROM are printed out.

The RAM size varies according to the destination.
The RAM size is checked upon power-on to automatically set 8KB or
32KB whichever used.
The RAM size type is printed starting on the 13th column on the RAM
test result print line.
After the printing is completed, the buffer area is initialized.
For the RAM verify test, 64 bytes of object codes on the ROM is
transferred to a particular area on the RAM.
11-2. Host terminal emulation mode (SWI-2:OFF,
SWI-3:ON, SW1-4:ON)
The SW3 status is read, and with the read value as the receiving
station address, a printout commantidata
packet is created and
transferred to the remote station. At this time, the transmitting station
address remains as previously set.

One packet is carried on one line, and a flag is set on the final packet.
If a transmit error status is returned from the SRN interface, the data
will be re-transmitted. If the transmission failed at the third try, the
status returned from the SRN interface will be printed out to terminate
the test.

3 seconds.
11-3. RAM verify (SWI-2:ON, SWI-3:OFF, SW1-4:ON)
At the end of 7-1. ROM/RAM test, the copy data in the verify area is
compared with the original ROM data, and the result is printed out.

11-5. Printout test (SW1-2:ON, SWI-3:ON,
SW1"4:OFF)
All internal character codes are printed in a black matrix pattern one
at a time. After that, a pattial cut is performed, and the same contents
as the first ones are printed out in red.
The above cycle of operation is repeated endlessly.
The program can be terminated only by turning power off.
11-6. SRN flag continuous transmission
(SW1-2:OFF, SW1- 3:ON, SW1-4:OFF)
The
SRN interface is reset, and the flag pattern continuous transmis-
sion diagnostic (diagnostic 3) is carried out. NO printout operation is
performed in this test.
The program can be terminated only by turning power off.
11-7. SRN packet continuous transmission
(SW1-2:ON, SW1-3:OFF, SW1-4:OFF)
The SRN interface is reset, and the packet continuous transmission
diagnostic (diagnostic 4) is carried out. No printout operation is per-
formed in this test.
The program can be terminated only by turning power off.
