You can also use the programmer to read information
from the D8125MUX and multiplex points. Refer to
Section 4.1 Connecting the D5060 Programmer on page
6 to install the D5060.
4.2.4.1 Reading Information from the D8125MUX
1.
To enter Interrogation Mode, press and hold [7]
and [9] simultaneously until the unit beeps.
2.
The LED marked INTERROGATION MODE lights.
A.dr appears prompting you to enter a starting
address.
3.
Enter an address followed by [#]. The
Interrogation LED flashes.
4.
Press [#] to read point information from the
D8125MUX at that address.
5.
Press [4] to read the previous address information
from the D8125MUX.
6.
Press [6] to read the next address information
from the D8125MUX.
If communication between the unit and
the D8125MUX fails, the unit sounds a
three-beep error tone and shows PnL.
7.
Exit Interrogation Mode by pressing and holding
[*] until the unit beeps.
4.2.4.2 Reading Information from MUX Points
Disconnect all multiplex points from the
D8125MUX and the multiplex bus before
reading multiplex point information.
1.
To enter Interrogation Mode, press and hold [7]
and [9] simultaneously until the unit beeps. The
LED marked INTERROGATION MODE lights.
2.
The display reads A.dr prompting you to enter a
starting address. Enter an address and press [#].
3.
Press [1].
4.
When t.YP appears at the keypad, enter the point
type of the multiplex point as shown in Table 4 on
page 8 and press [#].
5.

Wiring the D8125MUX to
Multiplex Points
Do not use shielded or twisted pair cable.
1.
Connect Power A+ and Power A- on the D8125MUX
to multiplex devices that require uninterrupted
auxiliary power. Refer to Figure 8 on page 9. Up to
200 mA is available at these terminals.
2.
Connect MUX BUS A+ and A- on the D8125MUX to
the positive and negative bus wires of the
multiplex points. The maximum allowable current
on MUX BUS A is 75 mA.
3.
Remove power from the D8125MUX before
connecting or disconnecting multiplex
devices. Connecting or disconnecting a
multiplex device while the D8125MUX is
powered could cause the multiplex device
address setting to reprogram or scramble.
