5.4 Options for attachment and settings of the TIM 3 and TIM 4 variants
Note
The following description of the possible settings on the integrated MD3 modem apply only
to the TIM 33 (6NH7800-3AA30) with a hardware version ≥ 6.
Settings with the DIL switches accessible from above
On the integrated MD3 modem, the metering pulse filter must be selected and the basic
setting for dial-up mode made. These settings are made using a 4-pin and a 10-pin DIL
switch. The 10-pin DIL switch, SW2 is located directly on the top housing grill. The 4-pin DIL
switch, SW1, can also be reached from above through the housing grill, however it is located
deeper within the housing and may therefore be more difficult recognize. To set this switch,
you require a long, thin tool, for example a small screwdriver or a toothpick.
The DIL switches have the following functions:
● 4-pin DIL switch SW1
● 10-pin DIL switch SW2
