Hubbing Module
GENERAL DESCRIPTION
T
he 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
F
ig. 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.
