you are attached to the right serial port. The easiest way to do this is to dis-
connect the SER-DMX and short between the Tx data out and Rx data in
pins on the serial port connector on the back of your computer. On all
IBMs and compatibles this means sticking a piece of wire, paper clip, or
similar tool between pins 2 and 3 on the 'Com.' connector. While still run-
ning the modem program, anything you type should be shown on the
screen while this paper clip is in place, while nothing will appear when you
remove it. If your computer passes this test, then you are using the right se-
rial port and the problem is most likely the baud rate setting or in your
wiring to the SER-DMX. If you get characters on the screen even with the
paper clip removed from the serial port, it means you probably need to set
the 'echo' mode to 'none' or 'full duplex' and try this test again.
To enter the configuration mode: Type the following. The (address) is re-
placed by the HEX value set when the SER-DMX is configured.
m5AA5(address)
If any other card is in configuration mode (or even if it just thinks
another card is in configuration), the SER-DMX won't be able to enter
configuration mode. To exit any other card from configuration type
'XN'. You can then try entering configuration again.
To display the status of this card: Send the card an ‘i(address)’. The
(address) is replaced by the HEX value set when the SER-DMX is con-
figured.
To download the configuration of this card: Prepare your computer to
receive and save a stream of ASCII characters. Send the card a
‘r(address)’. The (address) is replaced by the HEX value set when the
SER-DMX is configured. The card will respond with a stream of 1043
bytes of ASCII data. Any number of additional cards (either more SER-
DMXs or any other card made by Gilderfluke & Company) can also
have their configuration downloaded into the same file by giving
them the same command with the appropriate addresses appended
on. When you are done downloading configurations, you can tell
your computer to stop saving received ASCII to a file.
To reload saved configuration: All you need to do is send this file back
to the cards through your computer’s serial port. All cards that were
addressed will hear their address in the data stream and load in the
configuration data.
