S1-5 and S1-6: Clock Source
Switches S1-5 and S1-6 are set in combination to determine the transmit
clock source for the Model 1080ARC (see Table 3).
clock source for the Model 1080ARC (see Table 3).
S1-7: Asynchronous/Synchronous Mode
The setting for switch S1-7 determines whether the Model 1080ARC is in
asynchronous or synchronous operating mode (see Table 4).
asynchronous or synchronous operating mode (see Table 4).
S1-8: Carrier Control Method
The setting for switch S1-8 determines whether the carrier is “constantly
on” or “controlled by RTS”. This setting allows for operation in switched
carrier, multipoint and/or hardware handshaking applications (see
Table 5).
