JP1 -

VME Control This jumper sets the Master or Slave function of the board on the VME bus.

Note: Single-node D20 systems are always set to Master.

JP2 -

VME Address JP2 is a group of four jumpers that set the VME bus address of the board. The

address should reflect the board location in a D200 CCU chassis.

Example:The board with address 1 will be the lead node, with nodes 2

through 8 positioned to the right of the lead node.

Note: Single-node D20s are set to address 0 (all jumpers IN).

JP3-1 and

JP3-2

RTC Options

These two jumpers determine the Real-Time Clock (RTC) source for each

D20 ME board in a CCU:

• Single-node D20s and the first, or lead, node of a D200 both use an internal

clock.

• Non-lead nodes of a D200 synchronize the clocks to the clock of the lead node.

Introduction to Downloading Flash Code

Introduction Before you can put a D20ME module into service, it must have a firmware

application code loaded into memory.

All D20 ME boards use Flash memory to store the application code.

Serial

Download You can load the Flash code file serially into the memory of the D20 ME via

the 68K Monitor using most types of Windows communication software,

such as HyperTerminal.

Table: Identify

the D20 ME

Type

The D20 ME module type is determined by the version of BootROM

installed, which identifies how the module will be used. Because the

download method depends on which BootROM is installed, you need to

determine the type of D20 ME module before downloading the Flash code.

Note: The /xx in the Label column is the software revision number.

Module Type BootROM Label

D20 ME D20 Base SBU0000/xx

D20 ME CCU SBU0001/xx

Prerequisites

for Code

Download

You need the following items to successfully load a Flash code file into a D20

ME module:

• Windows PC with HyperTerminal (or equivalent) communication software

loaded.

• The code file, in the Motorola S-record format, located on a local hard drive. If

the file is located on a network or floppy drive, the download may be

significantly slower.

− This file is typically named: down.shx

• A WESMAINT cable for connecting the PC to the D20 ME WESMAINT serial

port.

• The D20 ME card:

− with the hardware option jumpers set

− installed in a D20 or D200 chassis and ready to power-up.

Upgrading

From D20M or

1 MB Flash

D20 ME?

Code files for previous D20M modules are created in a binary format, usually

called PROM.BIN files.

• If you are upgrading a device running a D20M to use a D20 ME, you must

convert the binary code file to a down.shx format before you can download it to

Flash memory.

• You must also use Config Pro to adjust the device’s Device Properties so that

the new processor will run the converted code file.

If you are upgrading from a D20 ME with 1 MB Flash (Part # 526-2003), you

must modify the Device Properties of the new configuration in ConfigPro to

use the existing code file.

For more information on upgrading from earlier versions, refer to the D20

ME Processor Module Installation and Operations Guide.

Procedure:

Setup To set up the equipment for downloading code files to the D20 ME:

Step Action

Configure and Connect PC to D20 ME

1 Connect a WESMAINT cable from the PC’s COM port to the D20

ME’s front panel WESMAINT serial port.

2 Start Windows’ HyperTerminal communication software on the

PC, and configure it as follows:

− 9600 Bps

− 8 bit

− no parity

− VT100 emulation

− Xon/Xoff flow control enabled

Identify the D20 ME Type

3 If you already know the D20 ME BootROM “type”, proceed to:

• Code Download – D20 ME - D20 Base or

• Code Download – D20 ME - CCU.

Restart the D20 ME (power off-on cycle) and watch the monitor.

If the first line of output text is: The D20 ME type is:

P149-0, D20 ME BootROM D20 Base

Code Download – D20 ME - D20 Base

Procedure:

D20 ME - D20

Base

The following steps demonstrate the serial download of a Flash code file to a

D20 Base type of D20 ME module using the 68K Monitor.

Step Action

D20 ME - D20 Base Code Download

1 Restart the D20 ME, again.

2 As soon as messages display on the monitor, press the ESCAPE key

within 5 seconds.

Result: A message displays, asking if you wish to mark the

configuration as “bad”.

3 To proceed with the download, type y.

5 Type sp to suspend all processes running on the D20 ME.

6 Type erase to clear the Flash. This will take several seconds.

Result: Flash Erased is displayed when completed.

Optional Step 1: To speed-up communication to shorten download time

7 Type Baud 38400 and press ENTER (speeds up to 230.4 Kbps, or

lower speeds may be chosen based on ambient EMI, cable length,

PC limits etc.)

8 Configure the HyperTerminal to communicate at the same speed,

and reconnect to the 68K Monitor.

9 If the communication software you are using does not have a

“progress indicator’, you can enable echo to display the code file

on the monitor as it is transferred.

The echo option can be usually found in the Communication

Settings or Properties of the communication program.

Note: Enabling echo may slow the transfer speed.
