Question: Can I continue to use my tape reader?
Yes, our installation adapts to the machines
standard reader input so normally you can easily re-attach the reader or
switch back to the reader via an A/B Switch. It is possible to use
the tape reader as an input device to the PC via the AMI, so you can read
your tapes into your computer for later download to the CNC, but this is fairly
difficult to get right.
Question: How long can the host cable be?
4,000 ft in RS422 mode. In RS232 mode the distance is determined by the
type of wire and baud rate. The RS232 EIA standard specifies only 50 ft of
cable at 20,000 baud, but allows doubling of the length for each halving
of the baud rate. 100 ft at 9600 and 200 ft at 4800, and 400 ft at 2400 is
well within specification.
Question: What machines do you have support for?
See our control
chart. We have interfaces for HUNDREDS of machines, and we would be
very surprised if you have one we have not interfaced.
Question: Can the AMI drip-feed?
Yes, the AMI can use its 128K memory as a "first in- first
out" buffer. In this mode the AMI allows any size program to be sent
to the CNC.
Question: Does the AMI handle loading of executive tapes?
Yes, the AMI emulates all the tape reader
functions including loading of the controls executive program. You must
convert the executive to a computer file, and have communication software
capable of sending BINARY data via the COM port. We have done this as a
service for hundreds of customers.
Question: What if my PC doesnt have a COM port?
Install one via USB, they are cheap and some work well. But, be carefull
not all USB COM ports provide full functionality. I fyou get the wrong type
you may not be able to load executive files for example.
AMI reader emulation trouble shooting|
|The 84 page AMI hardware Technical Reference provided with each
AMI has an extensive section on troubleshooting. Here are some tips in
case you have lost your manual.|
Symptom: Nothing is happening! |
|Question: Does the AMI Green LED light up?
|| Maybe power is not being
provided to the AMI, or there could be broken wire or
loose connection to the blue power jack|
Symptom: Green LED is ON but No communication! |
|Question Are you using a cable you just built?
||Try using ADR's
supplied host cable rather than your cable. You may have to move a
computer close to the machine to use it.
|Question: Are you sure you built the host cable correctly?
|| Check the pinout against the cable chart.|
|Question: Is your software set to use the right data
|| Set your PC for 9600,7E2 or 9600,8N2 depending on whether you are
using ISO or binary data. Default baud rate is 9600.|
|Question: Are you sure you are plugged into the right
connector on the PC?
|| Serial ports on the back of a PC are eight 9 pin male or 25 pin male
connectors. A female connector may be printer connector - or worse a
document scanner - could have power on pins that could damage the AMI.|
|Question: Do you have the modem lines connected in a
NULL MODEM configuration?
|| The AMI does not use modem lines
- XON/XOFF protocol must be used -
the PC may not output until the modem lines are driven right even though
you have selected XON/XOFF protocol in your software.|
|Question: When you press the RESET button on the
AMI do you see a copyright notice come out of the AMI?
|| If you do then
communication from the AMI is ok, the problem must be
one-way to the AMI. Check the transmit wire from the PC to the AMI. If the
copyright notice does not appear then communication both ways is not
working - check connections again.|
|Question: Is there a jumper on RS232 position
(AMI has four jumper positions)
|| You may have made a test with RS422 and forgot to switch back to
|Question: Are you sure that there is not a
conflict with another software program using the same COM port?
|| A mouse driver or serial printer
driver could be using the port -
disable these drivers/programs.|
Symptom: Can get into AMI setup, communication is ok, but CNC does not do anything!|
|Question: Is the AMI connected to the CNC correctly?
||Check that the cable/adapter is attached to AMI J5 and the cable goes
to the right connector on the CNC.|
|Question: Is the AMI set to the parameters
specified by ADR's application note for the machine?
||Each parameter is
critical to proper operation - verify each one.|
|Question: Is there a valid program in the
AMI prior to you starting the CNC running?
|| Start with a short simple program
- be sure it has a "%", "M30",
and leader/trailer codes if they are necessary.|
