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.
