WIM 8 (RD) Integrated Dry Pair Tester (DPT)
The WIM 8(RD) also features an integrated dry pair tester (DPT). The DPT can only be used in systems where there are two
WIM 8s.
When two WIM 8(RD)s are connected via dry pair, they can be put into “test mode.” In test mode, the WIM 8(RD)s will test
each dry pair using Dual Tone Multi Frequency (DTMF) and display the results on the LCD screen. Both WIM 8s must be
connected to the dry pair before testing can begin.
Note:
The test mode should ONLY be used before the game. The DPT should NEVER be used during a game
because in test mode, no communication over the dry pair is possible. However, there is a hard switch
on the rear of the WIM 8(RD) that can defeat the DPT. If you wish to remove all possibility that the
system will enter test mode during the game, that switch should be turned to the “Disable” position.
Note:
AC power is required on both ends of the system for test mode. The WIM 8 will operate with limited
functionality without local AC, but the DPT will not function.
You can start test mode from either WIM 8 in the system. To enter test mode, press the two user soft buttons under the LCD
at the same time and hold them for approximately 5 seconds. The LCD screen will display the results of the tests and give
options using the soft buttons.
The system will check each pair connected, whether through the RJs or Spring Jacks and report errors in continuity or
crosstalk.
It is important to note that the two units communicate over the first four pairs of wires. If none of the first four pairs of wires
are connected, the unit will exit test mode and report that no communication could be established with the DPT on the
opposite end of the system. If any one of the first four pairs is connected to the remote WIM 8(RD) in any of the first four
pair positions, the unit will enter test mode. At least one of those faults must be corrected before testing can be re-initiated
as the two units must have at least one good pair to hand shake and begin testing.
WIM 8 (RD) Screens
•
Splash Screen
– This screen is displayed for a few seconds at power up of a WIM 8 or WIM 8(RD).
•
Default Operating Screen
– This screen is displayed during normal operation of the WIM 8(RD). The display
shows all eight communication lines (1) and the status of both +24volt sides of those lines (2). A solid triangle
indicates appropriate intercom power is present on a particular side of an intercom channel. If you have a
4-channel X-System, there will be no triangles showing under lines 5 through 8.

To enter the “TEST MODE,” depress and hold the buttons (there are two) under the display directly below the
words “Test” (3) for five seconds. The WIM 8(RD) has a test disable switch on the rear that makes it
impossible for the unit to go into test mode. If that switch is in the “Disable” position, the display will alert you
and revert back to the Default Operating
Screen. If test is successfully initiated, you will
see a status screen for approximately 1
minute, then the fault screen will display.
