Step 1: Connect telephone line
❑
Connect a telephone line to the Polling Controller jack labeled “Telco Line”
using a standard modular cord (not supplied).
Step 2: Verify polarity of CO line wiring
❑
Use a standard polarity tester to check the polarity. Polarity must be
correct on the wiring to the units to minimize relay contact wear and avoid
“bell tap,” a momentary or single ring of the telephone bell.
Caution:
The unit should be powered down whenever you test polarity.
Step 3: Connect modem line
❑
Connect the polling modem to the Polling Controller jack labeled Modem
using a standard modular cord (not supplied).
Step 4: Connect power
❑
Connect the power cord to the Input Power jack on the Polling Controller
and the transformer to a non-switched, standard AC wall outlet.
Step 5: Test the installation
❑
The Power/Status indicator should begin flashing. If it is not on, check that
the power cord is securely connected and that the outlet has power. If the
LED is on bright, but does not flash, call Technical Support for assistance.
❑
After each LSS that will be polled by this unit has been installed, place a
call to each of its device ports and verify that the call is correctly routed. To
access the various LSS ports, refer to Table 3 to determine the routing code,
and enter a dialing string similar to the following:
ATDT4871515
∗
02
(With this dial string, the modem calls through the Polling Controller to LSS
Port 2. In this example, the LSS incoming line number is 487-1515.)
Installing Multiple Units in Carrier
The Polling Controller Carrier (model UM-112-801) is used for the installation
of up to eight M-390-A-04 Polling Controller units. See Figure 3. (The carrier is
available as an ordering option.) Follow the steps below to install the carrier
and Polling Controllers:
Step 1: Install carrier in rack
❑
Figure 3 shows mounting brackets attached to the carrier in the position
required to center-mount the carrier in a 19-inch rack. If the carrier is to be
front-mounted, reposition the brackets as appropriate.
