Black Box 5000 - Manual (Page 68)

Multiserver 5000
66
The Multiserver will connect port A4 to port A5
and you will get a CONNECTED message. Data
can now be exchanged between the two data
channels.
4. Pass data between the terminals in both
directions, and verify that the data has passed
correctly.
5. To disconnect, press the <break> key three
times within six seconds.
A SYNC C HANNELS A CROSS THE L INK
You can also test asynchronous channels across the
link. Follow the steps for testing async channels on
the local node.
When the ENTER CLASS prompt appears, type in
the following: remote/A6 (node id/channel #).
Pass data between the terminals in both directions.
To disconnect, press the <break> key three times
within six seconds.
C ONFIGURATION
All ports on the CCM (except A1) and on all CEMs
are by default async data channels. Section 9.3,
Asynchronous Channels
, explains all async channel
configuration options.
7.5 Testing Asynchronous Data Channels
During the Bench Configuration, you can test async
data channels on the CCM and any Channel
Expansion Modules that are installed in your
Multiserver.
A SYNC C HANNELS ON THE L OCAL N ODE
To connect and test a pair of async data ports,
proceed as follows:
1. Configure two async terminals per Table 7-1.
2. Connect your two terminals to any two async
data channels. For example, connect A3 and A6
on the CCM, B4 and B11 on the 12-Channel
Expansion Module, or A4 and B7. In Figure 7-4,
one terminal is connected to port A4; a second
to port A5.
3. At the terminal connected to port A4, press
<cr> and the ENTER CLASS prompt will
appear on the screen. Type in the following:
local/A5
(node id/channel #).
The Multiserver will prompt you for a password.
By default there is no password; press <cr>.
ENTER CLASS: local/A5
ENTER CLASS: remote/A6
ENTER PASSWORD: <cr>
ENTER PASSWORD: <cr>
