The Two Connection Methods.
EasyConnection modules can be joined together in two ways. The first
is to screw the end caps together, using the supplied screws in the
case of two or more modules; the second is to use the mounting bracket
where the module is to be joined to an earlier EasyConnection module.
Warning: Do not disconnect the
panel from the host adapter if the system is switched on.
Joining EasyConnection
Modules
It is essential that modules be securely joined
before use. To join two or more EasyConnection modules, perform the
following:
Step 1.
Ensure the modules are not connected to the host.
Step 2.
Remove the larger Phillips head screws from the plastic end panels
of the two ends to be joined.
Step 3.
Carefully join the male/female interface.
Step 4.
The phillips head screw is inserted through the non-threaded hole
of the end panel, into the threaded hole of the other and secured.
Repeat for other side.
Step 5.
Repeat to join a third and fourth (maximum of four) modules.
Joining Modules
with Earlier Modules
It is essential that modules be securely joined
before use. To join a module with an earlier type (those without the
end cap screws), perform the following:
Step 1.
Ensure the modules are not connected to the host.
Step 2.
Use the joining bracket supplied with the earlier module. This bracket
also serves as a wall-mount.
Step 3.
Carefully join the male/female interface.
Step 4.
Place the modules upside down on a flat work surface and lay the bracket
across the two modules so that the bracket is centred on the join
between the two modules.
Step 5.
Secure the bracket by screwing four phillips head screws, two per
module, through the hole in the bracket, into the centre seam running
down the middle of the underside of each module.
EasyConnection Expansion
EasyConnection supports up to four (4) modules
per board, with a maximum of:
- 32 ports per EC 8/32, and
- 64 ports per EC 8/64,
with all modules fully compatible with one another.
For example, 8 and 16 port DB25 modules can be connected in any combination
with 8 and 16 port RJ45 modules to produce customer specific port configurations.
Warning:
System malfunction and board damage may occur in the event that more
than 4 modules per board are connected, or where the 32 port (EC 8/32)
or 64 port (EC 8/64) board limit is exceeded.
Such malfunctions are likely to cause the resettable
fuse to be opened. The fuse is reset by powering down the host computer,
then rebooting.
DIP Switch Settings
The EasyConnection ISA boards have one eight
position DIP switch (SW1) which can select 256 different primary I/O
addresses when using EC8/32, and 128 different I/O addresses when using
EC8/64, in the address range 200h - 3FFh.
On the EC8/32, the secondary I/O address is
selected by registers in the primary address space, eliminating the
need for a second DIP switch. The value for the secondary address
is also in the range of 200h - 3ffh and occupies 32 bytes. The secondary
address may be shared by all boards.
The EC8/32-MCA, EC8/64-PCI and EC8/64-EISA boards
have no switches to configure. The EC8/64-EISA is configured by
the EISA configuration utility. The EC8/32-MCA is configured by the
Microchannel Configuration Utility and the EC8/64-PCI is configured
by the PCI BIOS.
Note: Various
DIP packages are used on Stallion boards. On the lever-type package,
the lever is pushed in the desired direction (i.e. on or off). On the
recessed variety you must press down on the desired end (on or off).
