Properly Installing the Programmer Hardware

1.3.2Power Connection

Connect the female end of the power cord to the PDS base unit.

The programmer can handle a power range of 105 to 265 volts AC at 47 to 440 hertz. All units are equipped with two power cords. If you are in the U.S.A., use the power cord with a male connector that can be plugged directly into a 120-V, 60-Hz power socket.

Outside the U.S.A., use the power cord with no male connector because the type of receptacle to be used is unknown. Attach the appropriate con- nector for your power receptacle. The wires are color coded as follows:

Green and Yellow = Earth

Blue = Neutral

Brown = Live

The gang programmer also requires an external power supply of 15 volts/2 amps. The connection for this external power is marked EXTERNAL POWER and is positioned near the top left corner of the programmer's socket board. Plug the the jack of the +15-volt wire into the external power socket. Connect the white-striped wire to the +15-volt terminal of the power supply and the solid black wire to the ground terminal of the power supply.

1.3.3Connection to a PC

1)Connect the end of the RS-232C cable consisting of a single 25-pin con- nector to the programmer.

2)Connect the end of the RS-232C cable consisting of two 25-pin connectors to the serial communication port of the PC. (If an IBM PC/AT is used, the 9-pin-to-25-pin converter cable provided must be used.)

1.3.4Connection to an XDS

Connect the programmer through an XDS if you want to use both the XDS Debugger and the microcontroller programmer, and if the PC has only one communication port. Or, even if you have enough communication ports but do not want to change the port number when you switch from one tool to the other, you can use this method. The programmer works as if it is connected directly to the PC.

Complete the following steps to connect the programmer through an XDS.

1)Connect port D of an XDS to the programmer by using the RS-232C cable supplied with the programmer. The male connector on the double-headed end of the cable connects to the XDS; the single-headed end connects to the programmer.
