USER MANUAL
The adapter will automatically recognize which media type is
installed. The parameters are bit mapped as shown in Table 5–4
with the baud rate selections given in Table 5–5.

Channel B – 1 = NRZI
0 = NRZ
Channel B – 1 = Full Duplex
0 = Half Duplex
Channel B – 1 = Synchronous
0 = Asynchronous
Channel A Baud Rate
(Bit 4 is MSB)
Channel B – 1 = Available
0 = Not Available
Channel A – 1 = NRZI
0 = NRZ
Channel A – 1 = Full Duplex
0 = Half Duplex
Channel A – 1 = Synchronous
0 = Asynchronous
NOTE
The Local Line interface will always be NRZI and
asynchronous regardless of the values in Option–01
or the dipswitch settings. When configuring the
channels, they must be either both synchronous or
both asynchronous. You cannot run synchronous on
one channel and asynchronous on the other.
