TIWAY I Gateway User Manual
3.2 Dipswitch Configuration and Function
Two
banks of dipswitches are located behind the access cover on the front of
the Gateway
. One is for the host port and the other is for the network port.
The following sections define the switches and describe the effect they have
on the Gateway’
s operation.
There are eight configuration switches for the host port, and ten for the
network port. The switch settings are binary coded so that Switch 1
represents the most significant bit (MSB) and Switch 8 or 10 represents the
least significant bit (LSB).
When setting the dipswitches on the Gateway
, check to make sure that the
settings match those on the host system and the network.
NOTE:
Most of the dipswitch settings are read by the Gateway only after a
reset. Any changes made to the dipswitch settings must be followed by a
reset. (Network port switches 7 and 10 are read and updated every scan.)
