CAUTION
•Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
•Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
•Keep circuit boards in their antistatic bags when they are not in use.
•Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
•For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference # TR-NWT-000870.

OPTION NUMBER FEATURES
A11-46035-01 Converter Module
GENERAL DESCRIPTION
The 46035 Converter Module provides a means of transmit- ting and receiving RS-232 and RS-422/485, converting it
to/from TTL, and applying it to a data communications subas-
sembly. It can then be transmitted and received using whatever
interface that subassembly uses. The table below lists Dantel’s
most common communications subassemblies.
The 46035 also provides external input/output of the intermedi-
ate TTL data.
The 46035 is a plug-in printed circuit board that fits into any
Dantel 400-type or similar equipment shelf. The module oper-
ates on -21 to -56 VDC input power. The front panel includes
transmit and receive LEDs for each port.
Strapping and switch setting of the module configures it for
RS-232, RS-422, or RS-485, RTS always ON, and terminated or
bridging RS-422/485 input.
The 46035 normally functions with other components of Dantel’s
460 Alarm and Control System (460ACS) to form a distributed
remote type alarm and control system. Refer to the Application
Information section of this manual.

Fig. 1 shows a functional schematic for the 46035 Converter Module. The circuit consists of:
Data Input/Output and Conversion Logic
The data input/output and conversion logic changes the data
input/output from its RS-232, RS-422 or RS-485 format to TTL.
The TTL data input/output is then applied to the communica-
tions subassembly, edge connector pins, and integrated circuits
that drive data-indicating LEDs.
RTS Control Circuit
The RTS control circuit is an NPN transistor acting as a switch.
With the RTS switch (S1-4) in the ON position, the transistor’s
collector is shunted directly to the emitter, which is grounded,
and grounds the RTS (pin 42 of the module and pin P5-12 of the
subassembly). When the RTS switch is OFF, the transistor’s
base receives an RTS signal or external CA input, which acti-
vates the RTS output.
Transmit and Receive Indicating LEDs and Drivers
The two front panel LEDs indicate transmission and receipt of
RS-232, RS-422 or RS-485 data. The transmit LED, labeled
XMT, is green. The receive LED, labeled RCV, is yellow. Inte-
grated circuits that are an integral part of the data input/output
conversion logic drive both LEDs.
A Power Supply
The power supply uses -21 to -56 VDC input power which
supplies +5 VDC and ±12 VDC operating power for the module’s
circuits and an on-board subassembly.

APPLICATION INFORMATION
Fig. 2 shows a 46035 Converter Module interfacing a 46020 Multiple Alarm Processor (MAP) printer port to a radio or
land-line data transmission system using a 49013 202 Tone
Modem Subassembly. This allows service personnel to access an
alarm system with a dumb terminal, or a computer acting as a
dumb terminal, from a remove service location. The alarm
system interfaces to the service site with a second 46035 Con-
verter Module.

The 46035 is also used to interface the printer port (RS-232) of
the MAP to an E2A remote polling TBOS. Refer to Fig. 3. Also
shown is the 46035 being used to interface a remotely located
alarm shelf.
Fig. 4 shows parallel wiring of two 46035 Converter Modules.
When two or more 46035 Converter Modules are wired in
parallel using RS-232 interfacing, handshaking must be used to
control the RS-485 signaling to the 46022-12 Multiple Alarm
Combiner. The CA to CF handshaking lines provide a true
RS-485 tri-state condition and prevent the Converter Modules
from interfering with each other.
Normally the MAP would have a 49008 RS-422/485 Current
Loop Interface Subassembly to interface its master port to the
RS-422 port (TBOS) of the E2A remote. By using a 46035 Con-
verter Module with a 49008 subassembly, the printer port of the
MAP can also be interfaced to the E2A remote. This allows
expanded display reporting.
The 46035 is also used to interface two remote site equipment
shelves to a central location. Refer to Fig. 5.
