Loop Back Check

Printer Print Check

1) Loop Back Check
1 Check
A LOOPBACK test on the built-in printer (UP-T80BP) interface
(logic channel 7 of RS232) is performed and the result is dis-
played. The test itself is the same as that for the RS232. The
difference in test specifications is as follows: The loopback signals
are for ER-DR, RS-CS, TXD-RXD only and the following LOOP-
BACK-Connectors are required.
CD
RD
SD
ER
GND
DR
RS

3-14. EFT (ER-02EF) Diagnostics

1) Procedure

1 Select "EFT Diag" in the DIAG MAIN MENU.
2 Power off.
3 The EFT starts up automatically by setting the whole 8-pin DIP
switch SW1 to OFF and then turning the main power switch ON.

2) Test

When powering up the EFT, the loop-back test of EFT CN's ER-DR,
ER-CI, and RS-CS is performed automatically.
Check the switch by turning on switch 1 to 8 of SW1 one by one.
Then, perform the sum check test of EFT ROM and the write/read
check of RAM.
Perform the same test as JOB300 for address 0000H, 0001H, 0002H,
0004H, 0008H, 0010H, 0020H, 0040H, 0080H, 0100H, 0200H,
0400H, 0800H, 1000H, 2000H, and 4000H of RAM.
