Re: Boss 5 RS-232 wiring

Nathan, see if this helps. It is a post I saved from alt.machines.cnc.


Here is the info you need.
1. Only connect to the local interface.
2. The connector you need is by AMP and comes in three parts as
follows
Plug 206434-1
3xPins 66570-3 (Get some spares ;-)
Clamp 182658-1
3. Connect as follows
AMP 25D
6--------------2
7--------------7
8--------------3
(Depending on your software you might need to link the hardware
handshake at
the 25D end)
(ie link 4 to 5 and link 6 to 8 to 20)
4. On Bridgeport Series 1 CNC it is necessary to remove the connector
labelled K-10 on the ERS card to enable the RS-232 compatible
interface.
5. Baud rate is set by one of two pcb mounted rotary switches (SW1 is
for
the local interface)
(Some were set with switches located in the ERS(RRS) card but I
haven't
seen one of these.)
0 = 110
1 = 150
2 = 300
3 = 2400
4 = 1200
5 = 1800
6 = 4800
7 = 9600
8 = 2400 again!
9 = 600
6. Set your PC to match the following
8 Data Bits
2 Stop Bits
No parity
7. Before you transfer in any data clear and reset the control
Put the control in edit mode
Send data in the following sequence
Control Q (Decimal 17)
Send the program one line at a time with CR at the end of each line,
you may also need to add a few Nulls at the end of each line
7/13/2002 http://groups.google.com/groups?
q=bridgeport+boss&start=90&hl=en&lr=&ie=UTF -8&selm=a4t80u%24ick%
241%...
depending on
the Baud rate you selected 4 @ 1200 or 16 @ 9600.
CR
CR (Terminates INPUT mode)
Control Z (Decimal 26) (closes memory and data loaded)
8. Put the control in edit mode
Send the following two characters
L (Decimal 76)
CR (Decimal 13)
The control will the list the program to the PC
Control Z (Decimal 26) (closes memory)
If you want to fully understand whats going on with the transfer
sessions
its a good idea to use a terminal mode and have a play with the
commands.
Things to note are that if the control has data in the memory it
starts in
edit mode and will send
BOSS 5.0 <CR> <LF>

>EDIT <CR> <LF>

*
you can then send the following commands
K <CR><LF> (Kills the text buffer area)
I <CR><LF> (Sets the system in input mode)
L <CR><LF> (Lists the text buffer area)
Control Z (Terminates Edit mode)
If the control memory is empty when you enter edit mode it will send
BOSS 5.0 <CR><LF>

>INPUT <CR><LF>

you can then send program data with Nulls or
<CR><CR> (Terminates input mode goes back to edit mode)
I hope that helps

Here is some info on commands. Most were determined imperically on my
BOSS6 so it may not be the same on your BOSS5.

Edit mode is entered by setting the mode select knob to "setup",
setting the "edit/remote" knob to "edit", and pressing it. If program
memory is empty, the control prints the following and enters input
mode:

BOSS 6.0

>INPUT

If program memory is not empty, the control prints the following and
enters edit mode:

BOSS 6.0

>EDIT

*

The following commands are available in edit, modify, and input modes:
<CR> When in input mode:
At end of line: enters block.
On blank line: exits input mode.
In edit and modify mode:
At end of line: enters command.
In modify mode:
On blank line: advances current block.
<ctl-Z> Exits and returns control to the operator
panel.

The following commands are available in edit and modify mode:

I Enter input mode. Insertion point is before
current block.
K Clears program memory and enters input mode.
L Lists entire program memory.
T Enters modify mode. Resets current block to
the first block.

The following commands are available in modify mode:
B Exits modify mode.
D Deletes current block.
N<#> Sets current block forward/backward <#>
blocks. <#> can be positive
or negative.
P<#> Prints <#> blocks. Does not change the
current block.
