OPTION NUMBER FEATURES
B11-46034-00 Hubbing Module
GENERAL DESCRIPTION
The 46034 Hubbing Module provides nine data ports for digital data summing, distribution or bridging.
Each port connects through six individual communication buses.
Ports one through eight can accept data through RS-232 and
RS-422 interfaces, depending on the strapping selection. Port
nine operates with an optional on-board communications subas-
sembly. The interface type depends on the selected subassembly.
If handshaking is required with RS-232 communications, the
module can operate up to five RS-232 data ports. One of those
five RS-232 data ports is port nine, operating with a 49029
RS-232 Current Loop Interface Subassembly.
The module comes with a TTL subassembly (bypass card) that
allows port nine to function as a TTL data bus interface in the
absence of a subassembly.
Interface and data connections are set using module switch and
strap options. Ports one through eight operate at a maximum of
38,400 baud. The maximum data rate for port nine depends on
the subassembly installed. Refer to the subassembly documenta-
tion for more information.
The 46034 Hubbing Module is a plug-in printed circuit module
that fits into any Dantel 400-type or similar equipment housing.
The module operates on -21 to -56 VDC input power.
CIRCUIT DESCRIPTION
Fig. 1 shows the 46034 Hubbing Module functional schematic.
Ports one through eight operate identically. Refer to Tables A
and B for specific pin assignments. Mini-jumpers 1A through 8A
selects port operation of RS-232, RS-422 terminated, or RS-422
unterminated data. Received data is inverted and goes to the
data bus for distribution. The received signal illuminates the
front panel RX LED.

46034-0997<90-00030> PAGE 3
The data bus consists of six individual, switch selectable data
lines which route the data to the desired ports. Data received
from the data bus applies to one input of a two-input OR gate.
The other OR gate input connects to switch S22 for full- or
half-duplex operation.
When switch S22 is in full-duplex mode (switch open), a con-
stant low applies to the input, which passes all data received
from the data bus to the port transmit circuitry. When S22 is in
half-duplex mode (switch closed), the input operates with the
port receive circuitry.
When the port is not receiving data, the input holds in the low
state and the OR gate passes data received from the data bus.
When the port receives data the input fluctuates between high
and low, enabling and disabling the OR gate and preventing port
data transmission.
The OR gate output applies to a driver that transmits data
through the RS-232 or RS-422 interface, depending on the strap
selection of mini-jumpers 1B through 8B. The signal illuminates
the front panel TX LED.
The ninth data port provides a mounting for installing various
communication subassemblies. With the five six-lever DIP
switches, the port supports the following interfaces:
♦TTL
♦RS-232
♦RS-422
♦RS-485
♦202 tone modem
The ninth data port has CA (pin 36) and CF (pin 18) control
leads for RS-232 subassembly applications.
When using a tone modem subassembly, strap C may be config-
ured to allow modem control by RTS command or strapped for
RTS always enabled. Use strap D for full- or half-duplex opera-
tion. When the strap is in the 1 position, the port operates in
full-duplex mode; when in the 2 position, the port operates in
half-duplex mode.
When the ninth data port is used with a bypass card subassem-
bly, front panel LEDs indicate RXD (receive data) and TXD
(transmit data) activity. When the ninth port is used with any
other communications subassembly, module and subassembly
LEDs indicate receive and transmit activity. Refer to the subas-
sembly documentation for LED operation information.
The 46034 Hubbing Module has an on-board power supply that
operates on -21 to -56 VDC input power. The unit supplies
±12 VDC and +5 VDC that powers the module circuits and an
on-board subassembly.

APPLICATION INFORMATION
Fig. 2 shows a 46034 Hubbing Module application diagram. The 46034 Hubbing Module is used primarily with Dantels
460 Alarm and Control System (460 ACS) and provides digital
data summing, distribution and bridging for the 460 ACS data
polling function. The unit can also be used with an on-board
subassembly for other data communications features such as a
modem or current loop interface.
Note: Use each of the six buses carrying data between the data
communication ports for one data polling system only. If more
than one alarm polling systems data routes to a bus, the
system does not function properly.

APPLICATION INFORMATION
SUMMING AND DISTRIBUTION APPLICATIONS
Fig. 3 shows a switch setting diagram for summing applications.
Each data port to be summed has its bus output switched to the
bus. The data port that is to receive the summed data from the
contributing data ports has only its bus input switched to the
bus. The switches also can be set for distribution of communica-
tions using a common data bus. The input from one port distrib-
utes to the output of the other ports.
The modules data communication buses route to the edge
connector which allows for bus expansion (pins 45 through 50).
Additional 46034 Hubbing Modules can share any or all of the
same buses which provides data summing/distribution/bridging
between data ports in different modules.
BRIDGING APPLICATIONS
Fig. 4 shows a switch setting diagram for bridging applications
using half-duplex communication. Each data port on the data
bridge must have bus input and output switches set to the bus
being used. Because each data ports bus input and output feed
to a common OR gate, the data port putting data on the bus
cancels its own input at the OR gate.
Fig. 5 shows a switch setting diagram for an RS-232 bridging
application using full-duplex communication. Module strapping
lets each data port provide either an RS-232 or RS-422 data
interface to the six data buses.
When strapped for RS-422 data, each of the eight data ports
receives and transmits data. When strapped for an RS-232
interface, two data ports may be required for each interface,
which limits the functioning data ports to four (not including
port nine). If CF and CA leads are not used, all eight ports are
available.

INSTALLATION
Installation consists of installing the subassembly, setting the module straps and switches, wiring the connector, and install-
ing the module in the equipment housing.
1. Install the subassembly.
If a different subassembly is to be installed, remove the three
screws from the subassembly mounting standoffs and carefully
pull the subassembly out of its connections.
If a TTL subassembly (bypass card) was installed, remove the
blue hole plug from the front panel subassembly window.
Install the new subassembly. Refer to Fig. 6. Ensure the subas-
sembly connector pins go into module receptacles J4 and J5. The
subassembly should sit down on the standoffs and the subas-
sembly front panel (except for the TTL subassembly) should
appear straight in the module front panel opening.
Reinstall the screws on the mounting standoffs.

2. Set the straps and switches.
Set the straps by removing the power supply. Remove the three
retaining screws from the subassembly and carefully pull the
subassembly out of its connections.
Once strapping had been verified or corrected, replace the power
supply subassembly by aligning the module connector pins with
the subassembly connector pins. Gently press the power supply
into place. Install the three retaining screws.
Refer to Fig. 7 and Tables C and D for setting straps and
switches.

OPERATION
Operation of the 46034 Hubbing Module consists of observing the 20 front panel LEDs that indicate the activity of all 9
ports. Refer to Fig. 9.
The first eight LEDs, labeled RX1 to RX8 respectively, indicate
receive (RX) activity for data ports one through eight.
The next eight LEDs, labeled TX1 to TX8 respectively, indicate
transmit (TX) activity for data ports one through eight.
The next two LEDs are not labeled and do not function.
The last two LEDs, labeled RXD and TXD, indicate data trans-
mit (TXD) and data receive (RXD) activity for the communica-
tions subassembly (port nine).
