1. DESCRIPTION
The DCB Conitel Async Adapter (CAA) converts 32 bit Conitel
SCADA protocol to asynchronous data. The CAA converts each 32-bit
protocol word into an ASCII, byte oriented protocol. The CAA allows
migration of Conitel SCADA from the ever more expensive and hard
to order analog phone lines to digital asynchronous data circuits,
including DDS, radio links, or Ethernet/IP networks using the DCB
EtherPath or EtherPoll.
The Conitel Async Adapter can be used in conjunction with the DCB
202T modem for connection to RTU devices with built in modems.
The transmit output of the 202T can be set to –16 dBm for connection
to built in modems that are sensitive to high receive levels.
The data port can be configured for speeds from 1200 to 57,600 bps.
Network speeds may be as high as 57.6 Kbps asynchonous or 12
Kbps synchronous.
The unit is configured using a network management port and an
asynchronous terminal or PC with terminal emulation software.
Configuration information is kept in non-volatile memory.
Some features of the CAA include:
•Monitor functions allow network management port user to
monitor transmit or receive of any data port.
•Many test features allow diagnostics of the system and
communications link.
•Power supplies available for 120 VAC, and 240 VAC.
•DC power options available.
•Built-in 56 or 64Kbps DSU/CSU option available.
•Rack mount options available.

. INSTALLATION
3.1 Unpacking
Remove the unit from the shipping container and examine it carefully
for external damage. If shipping damage is apparent, notify the
shipper immediately.
The following accessories are included with the unit:
•external power supply
•manual
•warranty, maintenance contract and repair information
•Modem to Composite cable (black) for connecting the unit to
an external modem or DSU/CSU
•Network Management Port cable (green) for connecting the
network management port to an asynchronous terminal or PC
for configuration
•If your unit has the optional built-in DSU/CSU, a cable is also
included for connection to the phone line.
3.2 Setup
The composite port must be configured properly for the type of link
used (Sync or Async). In addition, the data port must have the proper
speed setting. This is done using the network management port CN
and CP commands (see Section 5).
3.3 Using Leased Line Modems
In this section, a reference to modem includes modems, digital radios
or DSU/CSUs for leased line installations.
Connect the modems to the phone line and power ON the modems.
Confirm the presence of carrier at each modem. If carrier is not
detected at both ends, recheck the option settings. If carrier is still not
present, check the cable from the telephone line to the modem. If
everything is correct and still no carrier call the manufacturer of the
modem or contact the telephone company for assistance.
Connect the CAA composite port to the modem. A two foot RJ45 to DB-
25 male cable connects the composite port of the CAA (the RJ45
connector second from the left when viewed from the rear) to the data
port of the modem (usually a DB-25 female connector). See Section 6 for
cabling information.
7
Connect the unit to power.
Power and Modem Ready indicators on the front panel of the CAA
must be ON indicating the on-line condition. (See Section 4).
3.4 Optional Built-In 56 or 64 Kbps DSU/CSU
The optional DSU/CSU is configured using DIP switches accessable
from the rear of the unit. See Section 4 for a description and location
of these switches. The default settings should be correct for most
applications.
For line driver applications over customer owned wire (56K only), set
one unit for Master Clock and the other unit to Slave Clock.
3.5 Cabling
Cabling between the unit and the computer ports or terminal devices
is a common source of installation problems. The CAA must have data
from attached terminal devices or computer ports, as an input on
Position 6 of the RJ45 connector. Data from the CAA to any attached
equipment will be transmitted on position 5 of the RJ45 connector.
See paragraph 6.1 for position location on the RJ45 connector.
See Section 6 to determine the correct cables for your computer and
terminal devices.

3.6 Resetting Factory Defaults
The factory default settings for the CAA are as follows:
Data Port:
Rate 1200 bps
DCD to RxD delay 5ms
DCD holdover 12ms
Composite Port:
Modem type ASYNC
Rate 9600 bps
To reset the unit to factory defauls use the !R command from the
network management port or perform the following steps using the
front panel switches:
1. Depress and hold the SETUP switch while depressing the RESET
switch.
2. Be sure to continue to hold the SETUP switch until the unit
completes the reset and the lights return to normal.
3. All settings should be at the factory defaults. Use the SC (Show
Configuration) command to check the port settings.
