PPLICATIONS
Two or more Terminal Eliminator Plus units can be linked together to
increase the number of slave ports above 4 (or 8). This is referred to as
“cascading.” Run cable from slave port(s) of the “first-layer” TEP directly to
the master port(s) of one or more subsidiary TEPs. You can then run cable
from slave port(s) of these “second-layer” unit(s) to the master port(s) of one
or more “third-layer” units, and so on, to a maximum of four layers with 4096
available slave ports.
If you are cascading TEPs, putting the master in Conversation Mode with a
device directly connected to this TEP involves the same one-step process
described in the previous section. But activating a conversation with a device
on one of the
subsidiary
units requires additional steps. First, make sure that
the disconnect/abort command character for each layer of TEPs is different
(see
Section 4.2.7
). Then change the mode of each TEP between the master
device and the selected slave device one at a time, starting at the first-layer
TEP (the one to which the master device is attached) and working your way
upward to higher-numbered layers. Assuming that you’re starting from a
Concentrate-mode connection to the first-layer Terminal Eliminator Plus, to
Fig. 5-1. Accessing Conversation Mode with Cascaded TEPs.
From the console, type “C4[CR]” to put the console in Conversation Mode with the
master port of the second TEP, then type “C3[CR]” to put the console in
Conversation Mode with the selected device on port 3 of the second TEP.
