When using full duplex mode, users may hear an increased
amount of echo on the line. This may be more pronounced
when the TIF 2000 is forced into full duplex mode all of the
time (switch 8 up) rather than only when audio is present
(switch 8 down).
Internal DIP Switch (S202)
Internal DIP switch (see Figure 4) is accessed by removing
the top cover. To remove the top cover, remove and loosen
the screws as indicated in Figure 3. Remove the cover by
lifting up on the back portion of the cover. To reinstall the
cover, place the front portion into the grooves on the bottom
cover and slide the cover toward the front of the unit while
lowering the back of the cover. Replace and tighten the
screws that were removed or loosened as indicated in
Figure 3.
Zeus units use a 1-8 address scheme for their ports (e.g.
ports 1-8 have addresses 1-8, ports 9-16 have addresses 1-8,
etc...). CS 9xxx systems use a 1-10 scheme for port ad-
dresses (e.g. ports 1-10 have addresses 1-10, ports 11-20
have addresses 1-10, etc...).
To set the address for ADAM, ADAM CS, or Zeus systems
do the following:
1. Determine the port number that will be used for the
TIF 2000.
2. Locate the port number and its corresponding address in
Table 1.
3. Determine the DIP switch settings by looking up the
address determined in the previous step in Table 2.
4. Set the DIP switches on the back of the unit.
To set the address for CS 9xxx systems do the following:
1. Determine the intercom intercom port (audio channel
number) that will be used for the TIF 2000.
2. For port numbers ending in 1 through 9, the address is the
last digit of the port number. If the last digit is zero, use
10 as the address number
3. Determine the DIP switch settings by looking up the
address in Table 2.
4. Set the DIP switches on the back of the unit.
Full Duplex Method
Switch 8 controls the method by which full duplex opera-
tion is implemented in the unit. This switch only works if
full duplex mode is set via internal DIP switch (S202),
switch 7. If switch 8 is in the up positon , then the unit will
be forced into full duplex mode all the time. If switch 8 is in
the down position, then the unit will be forced into full
duplex mode only when audio is present.

Ring Count
Switches 1 and 2 determine the number of rings before the
unit auto answers. Note: The ring count is approximate.
These switches have no effect unless switch 1 on the rear
panel DIP switch bank is in the down position. To set the
ring count, consult Table 3.
