2.4SETTING UP THE EVALUATION BOARD AND THE HOST PC

This section tells you how to set up the board for use with a host PC. This section assumes you won’t be using some of the advanced features of the board when you first power it up. For additional options, such as selecting 80188 evaluation mode, refer to Chapter 3, “Hardware Overview.”

1.Make sure you are in a static-free environment before removing any components from their anti-static packaging. The evaluation board is susceptible to electro-static discharge damage; such damage may cause product failure or unpredictable operation.

2.Inspect the contents of your kit. Make sure that all items are included. Check for damage that may have occurred during shipment. Contact your sales representative if any items are missing or damaged.

CAUTION: Many of the connectors on the evaluation board provide power through non- standard pins. Connecting the wrong cable or reversing the cable can damage the evaluation board and may damage the device being connected. Use extreme caution when preparing to connect cables to this product.

3.Connect the power supply. The Intel 186 EC/EB Evaluation Board operates from a 5 VDC ± 10% power supply plugged into the J2 power connector (see Figures 2-1 and 2-2). This 5 volt signal is stepped down to 3.3 volts on the board. The connector housing and contact pins provided in your kit match the power supply to the J2 connector.

To select 5 V, place a jumper on pins B and C of jumper E1. To select 3 V, place a jumper on pins A and B of jumper E1. See Figures 2-1 and 2-2 for jumper locations.

All devices on the board operate at both 3.3 volts and 5.0 volts (except the LCD display, which is hardwired to 5 volts). This option allows comparison of current consumption when running code at either voltage. Separately packaged 5 V versions of the 80C186 processor and SRAM must be installed on the board for 5 V operation.
