Three Epson serial interfaces are suitable for EX printers. All three offer a wide range of baud rates, a choice of 7-bit or 8-bit data, and support Current Loop operation in addition to RS-232C. They also offer a choice of other features, which are listed in Table F-2. Table F-2. Serial interface 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 EX 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 F-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 F-3.
