About this guide This guide is designed to give you detailed information on how to install your C82303* interface board in a variety of Epson printers. Installation procedures vary slightly depending upon the printer model that you have. Also included, are instructions on how to adjust the settings of the C82303* interface board, as well as a general description of parallel data communication.
SETTING THE CONDITIONS The C82303* interface board has a set of DIP (Dual In-line Package) switches, and 6 jumpers. This switch and jumpers are used for selecting various interface operations. Board layout The diagram below shows the layout of the C82303* board, and the locations of the DIP switch and jumpers. Figure 1. Board layout DIP switch settings Before you install the C82303* interface, you may need to adjust some of the settings.

DATA ENTRY Table 3. Data latch timing selection Jumper J4 Function * ON Falling edge of B OFF STROBE OFF Rising edge of ON STROBE Note Either J4A or J4B jumper must be connected. Factory Setting ON OFF 1 About data entry To accommodate data entry, the C82303* interface board is equipped with a buffer that temporarily stores data before transferring it to the printer. When this buffer becomes full, any additional transmitted data cannot be accepted and is discarded.

SPECIFICATIONS SELF TEST The self test mode can be set by the DIP switch 1-3. To set, first turn off the power to the printer and then change the DIP switch setting. When the power is turned back on, the new setting automatically comes into effect. To exit from the self test, turn off the power and reset the DIP switch. The interface board first checks the RAM condition. After checking the RAM, data in the range between <3&H to <3!bH is sent to the printer and printed.
