PREINSTALLATION
Every installer should perform site evaluation prior to installing the transceivers. In order to perform this evaluation the following minimum equipment must be purchased from Carrier. The two modem starter kit (33CNWIRMOD) is re- quired to begin performing a site evaluation. The following components are in the two modem kit:
2 — standalone transceivers
2 — high gain
2 — transceiver power supplies
2 —
1 — copy of transceiver configuration software
1 — loopback connector
If the set up requires outdoor antennas they can be pur- chased from Carrier as part number 33CNOAANT1.
High gain directional antennas may be required to establish reliable communications. Directional antennas can be pur- chased directly from the antenna vendors described in the an- tenna selection and location section of this manual.
Site Evaluation Testing — Loopback Test — In order to perform a loopback test the transceivers must be con- figure Broadcast
To perform a loopback test it is necessary to connect each modem (one host and one remote) to its power supply. Then connect a PC with the Configuration Manager software to a modem using the
Perform the loopback test by executing the following steps:
1.Position the modems directly on top of each other and re- move both modem antennas if connected. Use a host and remote pair for this test.
2.Run the Configuration Manager on the computer and log into the software using the username “oem” and pass- word “oem”.
3.Select the Loopback Test program tab within the Config- uration Manager software.
4.In the Test String dialog box enter a text string such as
TESTING.
5.Using the pointer place a check in the Test check box.
6.Using the pointer select the Instantaneous RSSI option.
7.Press the Start button on the screen to begin sending the Test String.
8.The TX pane should start displaying the Test String at regular intervals. If the string is being received and sent back by the remote transceiver the RX pane should dis- play the same text screen. If the Test String is successfully transmitted through the loopback connector with the transceivers on top of each other proceed to Step 10.
9.If the RX pane displays “Timeout?” each time the Test String is sent then perform the following tests:
a.Verify that both transceivers are properly config- ured for Broadcast
b.Verify that both antennas are removed from the transceivers (NOTE: if antennas are connected and located too close together the two antenna fields will cancel each other out).
c.Verify that cycling power to the modems shows the
Fig. 1 — Loopback Configuration
10.After successfully establishing communications between the two transceivers locally, locate the transceivers in their desired locations and repeat Steps 2 through 8.
11.If the text string is being received and sent back by the re- mote transceiver the RX pane should display the same text string. If the text string is successfully sent and received the transceiver and antenna locations are acceptable. The green sync light should remain lit once the first data is sent.
12.If the RX pane displays Timeout? each time the Test String, is sent them perform the following tests or the sync light will not remain on:
a.Verify that both antennas are properly installed on the transceivers.
b.Reposition the transceivers such that the green sig- nal strength bar is as long as possible. Normally signal strengths above .5 are required for reliable communications (see Antenna Selection and Loca- tion section).
c.Attempt to utilize directional antennas in order to obtain reliable communications (see Antenna Selection and Location section).
INSTALLATION
Hardware Installation — Prior to installing the trans- ceiver(s), count and check all of the delivered equipment. A power supply and an antenna is required for each transceiver. The transceiver will be attached to either
Carrier recommends mounting wireless transceivers inside a building structure. Refer to Table 1 for temperature and humidity criteria when mounting transceivers. If an antenna is mounted outdoors or the CCN network extends outside of a building, use of an
To install the transceiver, perform the following procedure and refer to Table 1 for hardware specifications:
1.Insert the power supply male connector into the corre- sponding female connector slot on transceiver chassis.
2.Insert power supply plug into power (i.e., power outlet). Verify LEDs 1 and 2 on front panel blink three times. LED 1 should remain lit.
3.Attach the antenna to the transceiver.
NOTE: The antenna connection is a reverse thread SMA connection. It must be turned counterclockwise to attach.
4.Attach the male connector on the
