PollCat III Service Guide

4. Installation and Configuration

This section describes issues that should be considered when the
PollCat III has been installed and configured as described in the
User's Guide, but will still not function properly.

4.1. Installation Hints

4.1.1. PBX Interface

In order to correctly install the PollCat III, it is important to
understand the PBX interface. If the PollCat III has not been
properly adapted to the PBX interface, call records will not be
received, or may appear garbled or incomplete.

If call records appear garbled or incomplete, make certain that
communication parameters for the PollCat III PBX Port(s) match
those for the PBX (Section 4.2.1).

If the PBX LED on the PollCat III front panel does not blink when
call records are sent from the PBX system, this is an indication
that the PollCat III is not receiving call records. First, make
certain that all cables are firmly connected, then check to
determine that cables are appropriate for the PBX interface.
Check the following:

·

Connector: DB-25 or DB-9?

·

Gender: Male or Female?

·

Transmit Pin: Which pin is used to transmit data?

·

Handshake Requirements: Does the PBX require a high
handshake signal in order to release data?

·

Pin Assignment: Which pin must be held high in order to
release data ... Pin 5 or Pin 20?

These facts can be determined by referring to your PBX User's
Guide, or by testing the interface with a Breakout Box or
Voltmeter as described in this section. In many cases, the PBX
will use a standard DTE interface, transmit data on pin 2, and will
require a high handshake level on pin 5 or 20 in order to
release data.

4-1

4.1.1.1. Checking the PBX Interface with a
Breakout Box

A standard Breakout Box can determine which PBX interface pin
(usually pin 2 or pin 3) is used for data transmission.

1. If your Breakout Box that has two sets of LED's for each pin,
determine which LED indicates a negative voltage level.

2. Connect the Breakout Box to the PBX SMDR port and
monitor pins 2 and 3. One of these pins will indicate a
negative voltage level. The pin indicating the negative
voltage level is the transmit line.

3. If the PBX system does not require a handshake signal to
release data, you may see breakout box LEDs flicker
between positive and negative as call records are received.

4.1.1.2. Checking the PBX Interface with a
Voltmeter

A Voltmeter can also determine whether pin 2 or 3 is used for data
transmission.

1. Digital Voltmeter: Use pin 7 of the PBX SMDR Port (DB­25 interface) as a ground and measure for voltage with the
red probe. The transmit line will register a -11.5 to -12 VDC
voltage level.

2. Analog Voltmeter: Reverse polarity by running the red
probe to pin 7, and then use the ground probe to measure
voltage. The transmit line will register a -11.5 to -12 VDC
voltage level.

4.1.1.3. PBX User's Guide

The best source of information regarding the PBX SMDR interface
is your PBX User's Guide. When reviewing the PBX User's Guide,
note that many manufacturers identify RS-232 pin assignments
based on the nature of the device that will be connected to the
system.

For example, a Transmit (TX) signal from the PBX may be
identified as a Receive (RX) pin in the PBX User's Guide, based
on the fact that the device connected to the PBX will receive this
signal. When referring to the PBX User's Guide, make certain to
determine the true direction of each signal.

4-2

PollCat III Service Guide

4.1.1.4. PBX Indicators

The PBX indicators on the PollCat III Front Panel can be used to
determine if the cable connection to the PBX is correct.

1. After connecting the PBX to the PollCat III, turn on the
power to the PollCat III unit. If the cable configuration is
correct and the PBX system is active, the PBX will begin to
release call records.

2. The PollCat III's PBX indicator will blink each time a call
record comes through. This indicates the cable connection is
correct, regardless of whether or not the baud rate setting is
correct.

3. If the PBX LED remains lit constantly and does not blink,
this indicates that the cable configuration is not correct.

Note:

Some PBX systems will force the transmit line to go to
a positive voltage level, and will not transmit data
when the handshake level to the system is low or not
present.

4.1.2. Cable Kits

The following PollCat III cable kits are available from WTI:

·

PCK-3PC: For connecting the PollCat III to your PC.

·

PCK-3PBX: For connecting the PollCat III to the PBX
SMDR port.

·

MC-925-6: PollCat III Serial Card Interface to Modem.

These cable kits are designed to accommodate most common
interface requirements.

4-3

Installation and Configuration

4.2. Configuration Hints

After you have determined that the PollCat III is properly
connected to the PBX, check the following items related to system
configuration and filter definition.

4.2.1. Garbled Call Records

If the PollCat III displays call records that appear garbled,
irregular or incomplete, this is an indication that communication
parameters for the PollCat III PBX Port(s) do not match the
attached PBX system.

1. Access the PollCat III Command Mode and type ^B16

[Enter] to display the System Status Screen.

2. Check the Baud, Parity, and Bit settings for both PBX Ports.
Verify that parameters for both PBX Ports match the attached
PBX system.

3. Use Commands ^B92 (PBX Port A) and ^B93 (PBX Port B)
to set the communication parameters for PollCat III's PBX
Port(s) to match the attached PBX system. The procedure
for defining communication parameters is described in the
PollCat III User's Guide.

4. If communication parameters for the PBX are not known,
they can be determined by the process of elimination.

a) Access the PollCat III Command Mode and invoke the

^B94 command to activate the Monitor Mode. To
monitor the PBX connected to PBX Port A, type ^B94,A
[Enter]. To monitor the PBX connected PBX Port B,
type ^B94,B [Enter].

b) If records appear garbled, type ^B30 [Enter] to exit the

Monitor Mode. Invoke command ^B92 (PBX Port A) or
command ^B93 (PBX Port B) to select new
communication parameters, and then repeat steps "a" and
"b" until the correct baud rate is established.

c) If call records appear normal, PBX communication

parameters match the PollCat III. Type ^B30 [Enter] to
exit the Command Mode.

PollCat III Service Guide

4.2.2. Problems with Alarms and Filters

This section describes solutions for several problems often
encountered when defining Alarm Clues and Data Filters. For
more information on defining Alarm Clues and Data Filters, please
refer to the PollCat III User's Guide.

4.2.2.1. Testing Clues and Filters

When defining Alarm Clues, it is recommended to test each clue
before defining the next clue. To test clues, proceed as follows:

1. Define an Alarm Clue.

2. From a phone that is attached to the PBX system, place
several calls that match the Alarm Clue criteria.

3. Access the PollCat III Command Mode and invoke the ^B01
command using the following format:

^B01,clue,source [Enter]

Where:

clue Is the name of the clue being tested.
source Indicates the PBX Port that received the call

record. To review call records received via
PBX Port A, enter PA. To review call records
received via PBX Port B, enter PB.

4.2.2.2. The Asterisk Character (*)

When Alarm Clues are defined, the asterisk character is normally
used as a logical AND operator. Therefore, Alarm Clues cannot be
directly defined to search call records for the asterisk character.

If your application requires detection of asterisks in call records,
this can be accomplished by defining the Alarm Clue to search for
a range of characters that includes the asterisk. For example, to
create an Alarm Clue named STAR that will generate an alarm
whenever an asterisk is detected in call record field "A", define the
clue as follows:

^B81,STAR\1\A>'*A<, [Enter]

In this example, the asterisk character continues to function as a
logical AND operator, and the clue will search for characters with
a value that is greater than apostrophe ('), and less than comma (,).
The asterisk falls between these two characters.

Installation and Configuration

4.2.3. Incompatibility Between Modems

If the PollCat III is unable to make modem connections during a
Callback Routine at baud rates above 2400, this may be due to
modem incompatibilities related to error correction and data
compression.

This problem can usually be solved by disabling the error
correction and data compression features on PollCat III's internal
modem. Access the PollCat III Command Mode and use command
^B77 to re-define the Modem Reset Message as follows:

^B77,ATE0M0Q1&C1&D2&M0&K0S0=1 [Enter]

Note:

The "0" character in the above command line is a Zero.

For information on other modem related issues, please refer to
Section 10.

8. Memory Upgrade /
Replacement

Important:

·

Please read this entire section before beginning the
memory upgrade/replacement procedure.

·

When memory components are removed, stored call
records will be lost. Call records stored in the
PollCat's memory must be retrieved before
beginning this procedure.

·

Prior to beginning this procedure, it is strongly
recommended that currently defined PollCat
parameters should be saved to an ASCII file as
described in Section 8 of the PollCat III User's
Guide. Although alarm clues, data filters and
configuration parameters are not normally effected
by SIMM installation, saving parameters to an
ASCII file will provide a means for recovery in the
rare case that parameters are corrupted.

1. Power OFF the PollCat III and remove the top cover.

2. Locate the SIMM slots on the main PCB as shown in
Figure 2.3. Eight SIMM slots are available. Each slot
accepts up to a 1MB SIMM. This allows a maximum of
8MB for data storage.

8-1

Figure 8.1: SIMM Installation

3. Replacing a Defective SIMM: Locate the defective SIMM.
Remove the SIMM by rocking the module gently back and
forth until it comes free of the slot.

a) Position the new SIMM over the slot, and against the

SIMM guide.

b) Use your thumbs to carefully press the SIMM down until

it snaps into place.

4. Memory Upgrade: When upgrading 256K or 512K
PollCat III units to 1MB, the SIMM module in the first slot
(256K or 512K) must be removed and replaced with a 1MB
SIMM.

a) Remove the 256K, or 512K SIMM, by rocking the

module gently back and forth until it comes free of the
slot.

b) Install the new 1MB SIMM in the first slot. Position the

SIMM over slot and against the SIMM guide. Use your
thumbs to carefully press the SIMM down until it snaps
into place.

c) After installing the 1MB SIMM, the 256K or 512K

SIMM can be reinstalled in the next available open slot
on the PCB.

5. Replace the Top Cover and power ON the PollCat III.
Access the command mode and type ^B37 [Enter] to begin
the memory test.

a) If the test is successful, the unit will respond with the

“COMPLETE” message.

b) If the memory test detects an error, the unit will display

an error message that indicates the location of the SIMM
that failed. For example:

ERROR- SOCKET: 1MB, CHIP:M1

8-2

PollCat III Service Guide

6. Type ^B22 [Enter] to display the memory size. The

response message should indicate the correct upgraded
memory size.

Note:

When the original 256K or 512K SIMM has been
reinstalled in combination with a new 1MB SIMM,
Command ^B22 will return a “Memory Size Error”
message. Under these circumstances, this message
does not indicate a memory problem and should be
ignored. Command ^B21 can be used as an alternate
method to verify the memory size; type ^B21 [Enter].

7. Type ^B16 [Enter] to display the System Status Screen.

Check to make certain that unit configuration has not been
effected by the installation procedure. If configuration
parameters are intact, the unit is ready for operation.

a) If configuration parameters have changed, first reset the

unit to defaults by typing ^B50,2 [Enter]. Note that
all existing parameters, filters and clues will be cleared.

b) Use the ASCII file that was saved at the beginning of this

procedure to restore previously defined configuration
parameters as described in Section 8.3 of the PollCat III
User’s Guide.

c) If configuration parameters were not saved to an ASCII

file, they must be manually defined.

If this installation procedure does not produce the desired results,
please contact WTI Technical Support for further assistance.

9.2. Data Reception Problems

If the PBX system is sending call records, but PollCat III's PBX
LED does not flash to indicate incoming data, and call records are
not being stored, first check the following:

·

PBX Cable: The cable used for connection to the PBX
system must be compatible with PollCat III's PBX Port
interface. Note that the PBX Port interface is identical to the
9 Pin Computer Serial Port interface on most PCs. For more
information on the PBX Port interface, please refer to
Appendix A.1.

·

Communication Parameters: Access the PollCat III
Command Mode and issue the ^B16 command to display the

10-1

Figure 10.1: Modem Removal and Installation

10.3. Installing an External Modem

If your application requires an external modem, PollCat III can be
ordered with a serial card interface. Use a standard DTE to DCE
interface cable (Modem Cable) to connect to the modem.

Note:

The external modem must be powered on before the
PollCat III. This will allow proper initialization of the
external modem.

10.3.1. Serial Card Interface Installation

To install a serial card interface in an existing PollCat III unit,
proceed as follows:

Note:

During installation, stored call records, alarm clues,
and configuration data may be lost. Prior to
performing this procedure, it is recommended to poll
any stored data and save configuration parameters.

1. Disconnect the PollCat III from the PBX and retrieve any
stored call records from the PollCat III. Save currently
defined configuration parameters, filters and clues as
described in Section 8 of the PollCat III User's Guide.

2. Power OFF the PollCat III and remove the power cable from
the unit. Remove the Top Cover.

3. If your unit does not have an internal modem, proceed to
step 4 below. If the PollCat III currently has an internal
modem, proceed as follows:

a) Locate the modem clip (see Figure 10.1). Loosen the

screw that holds the modem clip, and slide the clip away
from the modem.

b) Pull the modem away from the modem connector.

4. Slide the serial card interface into the modem connector.
Make certain the card is configured for COM 2 and IRQ 3.

5. Slide the modem clip up against the serial card back plate
and tighten the screw on the modem clip.

6. Connect a standard PC to Modem Cable from the PollCat III
to the external modem. Make certain the modem is set for
factory defaults.

10-2

PollCat III Service Guide

7. Replace the Top Cover. Power ON the external modem, then
replace the power cable and power ON the PollCat III.

8. Access the PollCat III Command Mode and issue the ^B16
command to display the System Status Screen. If parameters
have been altered during installation, restore saved
parameters as described in Section 8 of the PollCat III User's
Guide.

Note:

·

WTI's Serial Card (P/N SC1) has a DB9M interface
(AT Style).

·

If your unit was previously ordered without a modem
or serial card interface for an external modem, the
modem clip may not be present. If your unit does
not have a modem clip (P/N 12393A), contact WTI
Technical Support as described in Appendix F.

10.3.2. Configuring an External Modem

When the PollCat III is attached to an external modem, the user
must issue the appropriate AT commands to fix the modem's serial
port at the highest compatible baud rate, and enable CTS/RTS flow
control. For example, when configuring a U.S. Robotics Sportster
modem, commands

&B1, &H1, and &R2 are used. This will prevent

the serial port baud rate from changing when the modem receives
an incoming call from a higher speed modem.

Due to differences between manufacturers, PollCat III's modem
initialization string does not include a command to fix the serial
port baud rate. Two different methods can be used to fix the serial
port baud rate and enable CTS/RTS handshaking. The user can
either invoke PollCat III's ^B77 command to redefine the
initialization string (See User's Guide), or enter commands
manually. Please refer to the User's Guide for your modem to
determine the appropriate commands.

When entering commands manually, make certain to pre-configure
the modem to a fixed rate by writing configuration commands into
a non-volatile memory template (e.g.,

&W0 for U.S. Robotics

Sportster) that will be read upon power up. This will eliminate the
need to re-configure the modem in the event of power loss.

10-3

Modem

10.4. Baud Rate Scanning

The PollCat III performs a scanning routine to determine the
highest baud rate available for communication with the attached
modem. This scanning routine will be performed with both
internal and external modems.

Upon power up, PollCat III will first assume 2400 bps is the
lowest available rate, then issue an AT command and wait for a
response from the modem at each standard baud rate above 2400.
When PollCat III reaches a baud rate where no response is
received, the unit will return to the previous baud rate (which
resulted in a response), and select that rate for communication
with the attached modem. After selecting the highest available
baud rate, PollCat III will send an initialization string to
appropriately configure the modem.

Note that the scanning routine only selects the baud rate for
communication between the PollCat III and its attached modem.
The scanning routine does not effect the baud rate used for
communication between the attached modem and the remote
modem.

10.4.1. 2400 Baud Internal Modems

If PollCat III includes an internal modem other than the standard
unit supplied by WTI, the System Status Screen (Command ^B16)
may indicate modem baud rates up to 57.6 K bps. Note however,
that even though the 57.6 K rate is displayed, modem
communication will actually be at 2400 bps. This is caused by a
combination of PollCat III's internal scanning routine (See
Section 10.4), and the nature of the internal parallel interface.

Due to recent technological advances, some manufacturers no
longer include UARTs in their internal modems, resulting in a
direct parallel interface between PollCat III and the internal
modem. Since the UART and modem components now reside on
the same chip, this eliminates the need to set a baud rate between
the UART and modem chip.

10-4

PollCat III Service Guide

In order to allow compatibility with older equipment, these newer
modems still respond to baud rate queries in the same manner that
their predecessors did. Since baud rates between the UART and
modem chip are no longer used, the newer modem will generate an
O.K. response for any baud rate. As a result, PollCat III's
scanning routine will always determine that the highest available
baud rate is 57.6 K bps.

This condition is mostly cosmetic and will not effect PollCat III's
overall performance. However the condition can be corrected by
accessing the PollCat III Command Mode and invoking command
^B90 to redefine the Modem Port baud rate as 2400 bps (e.g.,

^B90,2400,n,8,1).

10.5. Using Xmodem Protocol with
PollCat III High Speed Modems

It has been determined that V.42bis data compression, which is
commonly used with many high speed modems, is not compatible
with PollCat III's Xmodem protocol. When V.42bis compression
is used, the polling session will generate repeated "SHORT
BLOCK" or "BAD CHECKSUM" errors. In some cases, error
messages will continue until the communication software (e.g.
ProComm) aborts the session.

It is recommended that V.42bis data compression be disabled
whenever the unit is polled using Xmodem protocol. Two methods
for disabling data compression are as follows:

1. Disable Data Compression at Remote Modem: This is the
preferred method, and can be accomplished by issuing an
"AT" command to the remote modem prior to calling the
PollCat III. Appropriate AT commands for several common
modems are listed below:

·

US Robotics "Sportster" 14.4K: AT&KO

·

Hayes ACCURA 9600 - 14.4k: ATS46=136

·

Practical Peripherals "Practical Modem": ATS46=136

·

AT&T Paradyne "Data Port Express Modem": AT%CO

If your modem is not listed, please refer to the modem User's
Guide for information on appropriate AT commands to
disable V.42bis data compression.

10-5

Modem

2. Disable V.42bis at PollCat III Modem: If it is not possible
to disable data compression at the remote modem, data
compression can be disabled at PollCat III's modem. This is
accomplished by inserting the &K0 command into the
Modem Reset Message as follows:

a) Access the PollCat III Command Mode.

b) Issue the ^B78 command to display the current Modem

Reset Message. The default string is:

ATE0M0Q1&C1&D2S0=1

c) Invoke the ^B77 command to re-define the Modem Reset

Message as follows:

^B77,ATE0M0Q1&C1&D2S0=l&K0 [Enter]

d) When communicating with the PollCat III via modem,

disconnect and call the unit again before polling data.
The disconnect sequence will be sent, re-initializing the
modem and disabling V.42bis data compression.

e) When communicating via cable connection to the

Computer Port, issue command ^B90 to initialize the
modem before disconnecting from the computer port.

f) The PollCat III will now use the new string to initialize

the modem, disabling V.42bis data compression. It is not
necessary to issue these commands for each polling
session.
