Identifying a serial interface board All Epson interfaces have the EPSON name printed on them. If the board has an identification code printed on it, it will be a four digit number beginning with an eight. The number should be one of the numbers in Table E-3. If the board has no identification code, or if you are unsure whether the number you have located is the correct code, check the number of DIP switches' on the board against Table E-3. Table E-3.

X-on/X-off protocol is a system in which the printer transmits a code
to the computer to indicate that it cannot accept more data, and a
second code when it is once more ready.
The loopback self test mode allows direct testing of the functions of
the interface without connecting a computer; line monitor mode is
rather like the FX data dump mode.
Identifying a serial interface board
All Epson interfaces have the EPSON name printed on them. If the
board has an identification code printed on it, it will be a four digit
number beginning with an eight. The number should be one of the
numbers in Table E-3.
If the board has no identification code, or if you are unsure whether
the number you have located is the correct code, check the number of
DIP switches’ on the board against Table E-3.

Installing an Interface
Before installing an interface, you must remove the printer’s cover.
