Switches S1-1 though S1-4: Data Rate (Distance)
Switches S1-1 through S1-4 are set in combination to determine
two configuration parameters: synchronous data rate and maximum
distance. Maximum distance is determined by the space between data
packets in the communication stream between two Model 1180/35s.
The "2X" setting doubles the space between data packets, when
compared with the normal "1X" setting, and therefore doubles the
maximum distance. A setting of "2X" facilitates communication
distances up to 3 miles, and is available at certain data rates up to 64
kbps. A setting of "1X" supports communication at the normal distance
of 1.5 miles.

S1-5 and S1-6: Clock Source
Switches S1-1 and S1-2 are set in combination to determine the
source of the transmit clock for the Model 1180/35.

S1-7: DTE Control of RDL
The setting for switch S1-7 determines whether the V.35 DTE can
activate the RDL test by raising pin L. If DTE Control of RDL is
enabled, control from the front panel is disabled if there is no DTE
connected.
NOTE: If DTE control is not avialable, set Switch S1-7 to off.
S1-7 Setting
On DTE control of RDL enabled
Off DTE control of RDL disabled
S1-8: DTE Control of LAL
The setting for switch S1-8 determines whether the V.35 DTE can
activate the LAL test by raising pin N. If DTE Control of LAL is enabled,
control from the front panel is disabled if there is no DTE connected.
NOTE: If DTE control is not available, set Switch S1-8 to off.
