Gang Programmer Overview and Description

alone mode; it is ignored in PC mode. The red LED built into this switch is marked TMS370 power on and indicates that power is being supplied to the sockets on the gang programmer.

Do not insert or remove devices from the programmer while the red TMS370 power on LED is lit!

The main body of the gang programmer consists of 16 sockets whose type and arrangement are dependent on the type of gang programmer top you have. Below each socket is a red LED, which is used to indicate a failure of the device in the socket immediately above the LED. These sockets are mounted on base sockets to allow easy replacement if a socket is damaged.

The rocker switch on the top center of the gang programmer board is used to select program or verify when used in standalone mode; it is ignored in PC mode. The red LED just above this switch is lit when the switch is in the pro- gram position.

There are two green LEDs on the left top of the gang programmer. The top LED is marked PDS power on and indicates that the base unit is turned on. The low- er LED is marked external power on and is used to indicate that the external +15V is properly connected to the programmer top. The external power jack is located on the upper left side of the programmer top.

Typically, this programmer is used in PC mode to program initial units. Howev- er, you can use the 28-pin DIP socket at the top center of the programmer to program a 27C512 EPROM as a master device. As the master device is pro- grammed, a checksum is calculated and added to the configuration informa- tion stored in the master device. This allows the programmer to verify that the master device has not become corrupted before it is used to program addition- al units. Once programmed, this master contains all of the configuration data as well as the code to be programmed into the mocrcontrollers. Now, the gang programmer with the master device can be moved to a production environ- ment where you can easily program parts without the use of a personal com- puter; this is called standalone mode.
