Introduction and Installation
1.2.1
Operating the Gang Programmer in PC Mode
In
PC mode, the gang programmer is an interactive, menu-driven system that
facilitates programming TMS370 family devices and EPROMs. The system al-
lows you to perform any or all of the operations listed below.

Modify or add a new device to the device table
Verify any or all devices against either PC memory or the master device.
Upload any of the 16 devices.
Program the 512K master device.
Upload the master device with or without configuration data.
Enter standalone mode.

When you program in PC mode, all LEDs are turned on for a predetermined
time as part of an LED test. Then, the software checks whether a device exists
in each socket and whether it is properly installed by running a small read-write
test. If any device fails, the LED for that device blinks for a few seconds, there
are two short audible beeps, and the following error message is displayed:

If you have incorrectly inserted any device(s), you can fix them at this time. If
only empty sockets failed, you can continue the programming by pressing

of programming if there is a verification error on any other device, its LED turns
on also.

In the PC mode, the push button on the gang programmer is deactivated. The
interactive commands for this mode are discussed in Chapter 2 and 3.

Operating the Gang Programmer in Standalone Mode
In
standalone mode, the programmer works without the PC interface. You can
access the stanalone mode from the PC mode by selecting the standalone
command; when the PC is not connected to the Gang Programmer during
power-up, standalone mode is automatically selected.

After you install the master 512K EPROM device and any devices you wish to
program or verify, the procedure for starting the programmer is quite simple.
