46112 SynchMaster DATA CONTROLLER MODULE
The 46112 SynchMaster Module consists of:
RS-422 Drivers and Receivers
The RS-422 drivers and receivers are on a subassembly board
that mounts on the main PC board. The RS-422 drivers and
receivers provide data signal transformation from the module’s
internal TTL data bus to the specific parameters of the RS-422
interface.
A Clock
The RS-422 transmit and receive paths are clocked through the
main PC board because the line side data transmission equip-
ment is synchronous.
Terminating Resistors
Three subassembly board straps, designated X1, X2 and X3
provide for termination resistors. When you place the straps in
the “T” position a terminating resistor connects across the
RS-422 differential inputs. When you place the straps in the
“O” position you do not connect the terminating resistor.
Framing Generator and Detector
The framing generator inserts framing information into the
transmitted data. The framing detector reads the incoming data
and properly sequences the data to and from the microprocessor.
Proper sequencing prevents the data from individual ports
becoming intermixed.
Microprocessor
The microprocessor is resident for completing asynchronous/
synchronous conversion of the data as well as multiplexing the
data.
Status Indicating LEDs
The 46112 SynchMaster module’s green status indicating LEDs
are designated as follows:
¨TX INSERT When data is transmitted to a port config-
ured for the 46112 SynchMaster module, the TX INSERT
LED will light.
¨TX REPEAT When lit, the TX REPEAT LED indicates
that data is not being transmitted at the site. Either the TX
REPEAT or the TX INSERT will be on alternatively.
¨RX SYNCH Refer to the margin note to the left.
NOTE:
In the event of a failure, as well
as during installation, the RX
SYNC LED is an important indi-
cation of the soundness of the
64KB side of the SynchMaster
system. This LED appears as ei-
ther on or off if there is no syn-
chronization signal detected.
When the 46112 SynchMaster
receives a good synchronization
signal the RX SYNC LED ap-
pears to turn on solid.
A closer examination however,
reveals that the LED is actually
alternating on and off at a very
high rate. The LED appears to
“flicker” slightly.
CIRCUIT DESCRIPTION

PAGE 4 46112/113-0299<90-00032>
Configuration Straps
The configuration straps set the line clock polarity. When you
set the straps in the POS position, data changes at the rising
edge of the clock pulse signals. When you set the straps in the
NEG position, data changes at the falling edge of the clock pulse
signals. Straps are set for POS edge trigger from factory and
should not be changed in the field.
A Power Input Decoupling Network
The power input decoupling network is a capacitor array that
filters and isolates noise from the +5 VDC operating power. The
46113 SynchMaster module power supply supplies operating
power to the 46112 and 46113 SynchMaster modules. If more
than one 46113 SynchMaster module is at a location only one
46113 SynchMaster module supplies power to its associated
46112 SynchMaster module.

CIRCUIT DESCRIPTION
NOTE:
When the unit initially powers
up, the TX REPEAT LED blinks
on and off at a one second inter-
val if you set any 46113 Synch-
Master port switches incorrectly.
If this happens, recheck the
46113 SynchMaster module
switch settings.

46112/113-0299<90-00032> PAGE 5
46113 SynchMaster DATA PORT MODULE
The 46113 SynchMaster Data Port Module consists of:
RS-232 and RS-422 Drivers and Receivers
The RS-232 and RS-422 drivers and receivers transmit and
receive drop side data in their respective formats. The receivers
transform the data to the TTL levels for use by the UARTs.
Terminating Resistors
The RS-422 inputs have strap enabled terminating resistors that
operate the same as the 46112 SynchMaster module terminat-
ing resistors. T = terminate; O = open.
UARTs
The UARTs (Universal Asynchronous Receiver/Transmitters)
convert the drop side serial data to a parallel data format and
send and receive data to and from the 46112 SynchMaster
module.
The UARTs also control the serial data format (including baud,
number of data and stop bits, and so on). DIP switches set the
serial data format. The serial data format controls 46112
SynchMaster module programming (at initial power-up) for
each UART which determines each port’s data format.
Configuration Switches
The 46112 SynchMaster module’s microprocessor reads con-
figuration switches which programs the 46113 SynchMaster
module’s UARTs. The switches determine the operating mode,
the number of data and stop bits, the parity and the baud (data
transmission) rate and set the channel number.
Status Indicating LEDs
There are two sets of four green front panel LEDs.
The top four LEDs are labeled TXD (ports A to D) and light up
when the port (A, B, C or D) drop side equipment transmits data
through the 46113 SynchMaster module.
The bottom four LEDs are labeled RXD (ports A to D) and light
up when the port (A, B, C or D) receives data from a remote
46113 SynchMaster module and transmits the data to the drop
equipment
A Power Regulator
The regulated power supply operates on -21 to -56 VDC and
supplies operating power for the 46113 SynchMaster module’s
circuits. The power supply also supplies regulated +5 VDC
output power (through edge connector pin 22) for operating the
46112 SynchMaster module’s circuits.
NOTE:
To leave a port unused (inactive),
place all configuration switches
for that port in the ON position
and set the port to an unused
channel number. Failure to do so
will result in all ports operating
sporadically.
CIRCUIT DESCRIPTION

PAGE 6 46112/113-0299<90-00032>
You 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
NOTE:
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.

INSTALLATION
Installation consists of setting the straps and switches, wiring the pin connectors, and mounting the module in the shelf.
1. Set the 46112 SynchMaster Module straps.
Refer to Fig. 7. Each 46112 SynchMaster Module has two
2-position strapping points that configure the line clock polarity.
The first two points are TXCPOL and RXCPOL. When in the
POS position, data changes at the rising edge of the clock pulse.
When in the NEG position, data changes at the falling edge of
the clock pulse.
Set the RS-422 Interface Subassembly straps. Refer to Fig. 7.
When you place the straps in the “T” position a terminating
resistor connects across the RS-422 differential inputs. When
you place the straps in the “O” position you do not connect the
terminating resistor.
2. Set the 46113 SynchMaster Module straps.
Refer to Fig. 8. The 46113 SynchMaster Module has four
3-position strapping points that allow terminating resistors for
use on the receiver circuits. The resistors are labeled TRMA,
TRMB, TRMC and TRMD.
♦When placed in the “T” position, the terminating resistor
connects across the RS-422 differential inputs.
♦When placed in the “O” position, the terminating resistors do
not connect.
♦To prevent a misleading front panel indicator, place in the
“G” position for all applications except those using RS-422.
3. Set the 46113 SynchMaster Module switches.
The 46113 SynchMaster Module is the only module with
switches. Refer to Fig. 8, Table A, and Table B.
There is a maximum of 32 time slots available in a
SynchMaster system. The baud rate of the equipment utilizing
any one port determines how many time slots that port requires.
The higher the baud rate, the more time slots it will need. Table
C shows the relationship between baud rate and time slots
(addresses).
Table D depicts a sample system and shows the relationship
between addresses used and baud rates.
Table E is included for your use.
NOTE:
Use factory-set strapping
options. Change the strapping
options only for special applica-
tions.

Make a list of all of the ports to be used along with their specified
baud. Add all of the baud rates together and verify that the total does
not exceed 38.4 kbits. (An example port baud/address list as well as
blank list forms follow the switch settings table below.
Assign port addresses to the highest baud rates first, followed by
progressively lower rates. Each time an address is assigned, note
which addresses become unavailable, then go on to assign the next
port to be used to the next available address.
Allowable address switch settings for specific data rates are listed
below. Note that not all 32 addresses are available to ports with data
rates higher than 1200 baud.
All switch numbers listed are for individual switches on a port's DIP
(i.e. - to set the address of Port B, DIP switch 2, switches 1 through 5
would be used). The switches are assigned as follows; DIP switch 1 for
Port A, DIP switch 2 for Port B, DIP switch 3 for Port C and DIP
switch 4 for Port D.

NOTE:
When the unit initially powers
up, the TX REPEAT LED blinks
on and off at a one second inter-
val if you set any 46113 Synch-
Master Module switches incor-
rectly. If this happens, recheck
the 46113 SynchMaster Module
switch settings.
OPERATION
Operation of the 46112 and 46113 SynchMaster Modules consists of observing the front panel LEDs. Refer to Figs. 11
and 12.
46112 Status indicating LEDs
The 46112 SynchMaster Module’s green status indicating LEDs
are designated as follows:
¨RX SYNC The RX SYNC LED lights up when the
46112 SynchMaster Module receives frame information
properly.
¨TX INSERT When data is transmitted to a port config-
ured for the 46112 SynchMaster Module, the TX INSERT
LED will light.
¨TX REPEAT When lit, the TX REPEAT LED indicates
that data is not being transmitted at the site. Either the TX
REPEAT or the TX INSERT will be on alternatively.
46113 Status indicating LEDs
There are two sets of four green front panel LEDs.
The top four LEDs are labeled TXD (ports A to D) and light up
when the port (A, B, C or D) drop side equipment transmits data
through the 46113 SynchMaster Module.
The bottom four LEDs are labeled RXD (ports A to D) and light
up when the port (A, B, C or D) receives data from a remote
46113 SynchMaster Module and transmits the data to the drop
equipment.
