Gilderfluke&Co BR-MultiBrick32 - Manual (Page 38)

If you have hooked up the BR-MultiBrick32 to your computer and it still
doesn't seem to respond to the keyboard, the first thing to check is that you
are attached to the right serial port. The easiest way to do this is to discon-
nect the BR-MultiBrick32 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 running 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 serial port and
the problem is most likely the baud rate setting or in your wiring to the BR-
MultiBrick32. 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 you need to type the following. The
(address) is replaced by the HEX value set on the ADDRESS switches on the
front of the BR-MultiBrick32:
m5AA5(Card Address)
If any other card is in configuration mode (or even if it just thinks anoth-
er card is in configuration), the BR-MultiBrick32 won't be able to enter con-
figuration mode. To exit any other card from configuration type 'XN'. You
can then try entering configuration again.
Most of the configuration of a BR-MultiBrick32 is done using the address
and dipswitches. When you enter configuration, if the BR-MultiBrick32 is op-
erating as a 'Smart' Brick, it will display the following screen:
