16.1.4 Front Panel
The front panel (see Figure 16-4) of the Universal
Checkback Module has a PC connector, two
momentary switches, and ten LEDs. All of these
are described later in this chapter.
16.1.4.1 PC Interface
The top of the front panel has a DB9 female
connector labeled "PC INTERFACE" (see Figure
16-4). This connector is provided so that you can
plug in a serial cable connected to a serial commu-
nication port on your PC or laptop. This should be
a standard cable without a null modem. Once
connected, you can control the module (and any
other Universal Checkback Modules in the
network) from your PC or laptop. For complete
information on using your PC to control the
module, please see the "Using Your PC to
Communicate with the Universal Checkback
Module" section later in this chapter.
16.1.4.2 Front Panel Switches
Just beneath the PC interface on the front panel are
two recessed, momentary switches labeled "TST"
and "RST" (see Figure 16-4). As shipped from the
factory, the simplest way to interface with the
Universal Checkback Module is through these two
switches. You can use the top switch ("TST") to
initiate tests and the bottom ("RST") for clearing
alarms or canceling the carrier recovery mode.
Here is how they work:
TST (TEST) Pressing and releasing this
switch initiates a checkback
test. Pressing and holding this
switch for at least two
seconds initiates a loopback
test.
RST (RESET) Pressing and releasing this
switch clears any (major or
minor) alarms. Pressing and
holding this switch for at least
two seconds clears the carrier
recovery mode.
TST+RST Pressing and releasing both
switches simultaneously
toggles the automatic test
state. For example, if auto
tests are enabled, they
become disabled. They are re-
enabled after you press these
two again. Note that when
you disable automatic testing,
all front panel LEDs, except
the one labeled "CHECK
OK" and the one representing
the active settings option,
begin to flash. When you
press the switches again and
re-enable automatic testing,
the LEDs stop flashing.
16.1.4.3 Front Panel LEDs
The module's front panel has ten LEDs. When you
first power up the module, all ten LEDs flash
momentarily. After that, they all go off, except the
green LED on the left that indicates the current
DIP switch settings. The LEDs work as follows:
LED Function
1 When lit, this green LED indicates that
the module's DIP switch is set to Factory
Preset #1.
2 When lit, this green LED indicates that
the module's DIP switch is set to Factory
Preset #2.
3 When lit, this green LED indicates that
the module's DIP switch is set to Factory
Preset #3.
4 When lit, this green LED indicates that
the module's DIP switch is set to Factory
Preset #4.
C When lit, this green LED indicates that
the module's DIP switch is set to Custom
Settings Enabled.
1&4 When both LEDs are lit, this indicates
that the module’s DIP switch is set to
Factory #5 ||
