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 depend- ing 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.

The C82303* option package contains the following items:

C82303* parallel I/F board (1) FG plate

3

SETTING THE CONDITIONS DIP switch settings

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.

Before you install the C82303* interface, you may need to adjust some of the settings. When making DIP switch setting changes, it is best to use a pointed device, such as a ball-point pen or small screwdriver.

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

Caution All changes of DIP switch and jumper settings should be made with the printer power turned off. The printer checks and recognizes new settings only at the time the power is turned

About DIP switches

A set of DIP switches on the C82303* is labelled SW1. SW1 contains a number of individual toggle type switches that can be set either on or off. The individual switches are referred to by set (SW1) and number. Therefore, the switch in set SW1 marked by the small number 3 is called DIP switch 1-3.

Jumpers

The jumper is a small terminal used for connecting or discon- necting a circuit. The jumper is on when the jumper plug covers both wires of the terminal. Jumper settings can be changed by either attaching or removing the rectangular jumper plug. If the jumper is to be turned off, connect it to just one of the two terminal pins as shown in the figure below. By doing this, you can avoid losing the unused jumper plug. Figure 2. lumpers

Note 1. SLCT IN signal can be fixed LOW by setting the printer

DIP switch , jumper or SelecType function. If this signal is fixed Low, you should not connect J1. When J1 is ON, SLCT IN signal (pin No. 36 of I/F connector on the I/F board) is connected to the printer through the I/F board to enable it to be controlled by a Host computer. Sampling this signal is always carried out by the printer, therefore this function depends on the printer specification.

J2 and J3 jumpers are connected at the factory, and you should not change these setting.

DATA ENTRY Factory Setting

ON About data entry

OFF To accommodate data entry, the C82303* interface board is 1 equipped with a buffer that temporarily stores data before I

transferring it to the printer. When this buffer becomes full, any additional transmitted data cannot be accepted and is discarded.

The buffered data is transferred transparently to the printer main board every time the printer enters the READY state. A maximum of 512K bytes of data can be buffered with this board depending on its setting.

1. Data transmission: S-bit parallel

2. Synchronization: External supplied STROBE pulse

3. Handshaking: Via ACKNLG or BUSY signals

4. Logic level: TTL level

5. RAM capacity: 32K bytes

6. Connector: 57-30360 (Amphenol), 36 pin or its equivalents .

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. The print out is only 80 columns wide. Table 4. Self test mode
