ou can use the 46112 SynchMaster Data Controller Module
and 46113 SynchMaster Data Port Module for interfacing
digital transmission equipment (such as fiber optic terminals,
microwave equipment, and so on) and asynchronous transmis-
sion equipment (such as Dantel’s 460 Alarm and Control Sys-
tem).
Fig. 3 shows a terminal mode application. Fig. 4 shows pin-for-
pin wiring of the terminal mode application. A single 46112
SynchMaster Module controls data I/O (Input/Output) from up
to 32 asynchronous ports. Up to eight 46113 SynchMaster
Modules provide the 32 asynchronous ports (4 ports per 46113
SynchMaster Module).
Fig. 5 shows a simple repeater mode application. Each line side
port requires two 46112 SynchMaster Modules and from two to
sixteen 46113 SynchMaster Modules. With interconnected
46112 SynchMaster Modules one repeater setup is the same as
two terminal setups.
In this mode, you can transmit and receive data from two
different directions. You can drop data received from the west
direction of the 46112 SynchMaster Module to the 46113
SynchMaster Module. You can also repeat (transmit) through
the east direction line side through the other 46112
SynchMaster Module. You can also transmit data from east to
west.
Fig. 6 shows a repeater terminal application. Port A switches
are in terminal mode for address 1 on both the west and east
46113 SynchMaster Modules (drop side). Data received from
that port’s west direction is always dropped at the west 46113
SynchMaster Module port A. The west 46112 SynchMaster
Module transmits west data to the east direction if the channels
are in repeat mode. The data traveling from east to west trans-
mits the same way.
APPLICATION INFORMATION
N
OTE
:
Any combination of the repeater
modes can be used together in a
system with a maximum of 32
asynchronous ports. The system
must not exceed the drop side
bandwidth, for all ports, of
38.4 kbs, or 19.2 kbs on any one
port.
