The Advisor gives you breakout box and jumpering capabilities
for RS-232/V.24 circuits. The figure below shows the breakout
box and its associated connections. Note that the large black
arrows point to the RS-232/V.24 test connectors on the side of
the Advisor. The rearward connector is the preferred test input
for most tests. The forward connector should only be used when
signals need to be isolated by the rocker switches or
cross-connected by way of the switch jacks and jumper leads.
All 25 leads are accessible for jumpering on either side of the
breakout switches (the lateral switch bank numbered 1 through
25.) If you want to monitor or simulate on auxiliary data
channels or to observe control signals other than RTS, CTS,
DTR, DSR and CD, you can perform the appropriate
transpositions by opening the corresponding switches and
jumpering between the appropriate leads. To do so, connect the
circuit under test to the Advisor through the forward RS-232
test connector and perform the necessary transpositions over
the lateral switch bank.
The vertical switch bank provides hardware isolation of
incoming or outgoing data and control signals for special
purpose testing. An example would be using the Advisor to
supply terminal generated control signals without conflicting
