User's Manual

LEDR Series radios are supplied from the factory in matched pairs and are configured to user’s specifi-
cations. There are a few steps necessary to place the pair on-the-air communicating with each other.
Once this is done, system-specific parameters will need to be reviewed and changed to match your
requirements. Below are the basic steps for installing the LEDR radio. For more detailed instructions,
please see “INITIAL STARTUP AND CONFIGURATION” on page 25. When making cable connections,
refer to Section 3.6, Rear Panel Connectors , on page 17 for a rear panel view of the radio.
1. Install and connect the antenna system to the radio
• Ensure a path study has been conducted and that the radio path is acceptable.
• Use good quality, low loss coaxial cable. Keep the cable as short as possible.
• Preset directional antennas in the direction of desired transmission/reception.
2. Connect the data equipment to the rear panel data interface
• The data interface should be an RJ-45 connector for Fractional-T1, Fractional-E1, or E1, and a
DB-25 connector for EIA-530.
• Verify the customer premises data equipment is configured as DTE. (By default, the LEDR radio is
configured as DCE.)
3. Apply DC power to the radio
• Verify that the line voltage matches the power supply input range (typically 24 Vdc or 48 Vdc).
• The power connector is a three-pin keyed connector. The power source can be connected with
either polarity. The center conductor is not connected.
• Ensure the chassis Ground lug is connected to an appropriate ground point.
4. Change SUPER password and set up user access
• Login to Network Management System, using the password
SUPER
.
(See
“login” on page 68
.)
• Change the password using the
PASSWD
command. (
See “passwd” on page 72.
)
• Set up required users, passwords and access levels using the
USER
command, as required.
(
See “user” on page 86.
)
5. Set the radio’s basic configuration using front panel or Console interface
• Set the transmit/receive frequencies (
TX xxx.xxxx
/
RX xxx.xxxx
) if they need to be changed from the
factory settings. (See
“freq” on page 59
.)
• Refer to this manual for other configuration settings.
6. Verify and set the following parameters as necessary to allow data throughput and intercon-
nection with the network.
• RF transmit and receive frequencies. (See
“freq” on page 59
.)
• Radio modulation type and data rate parameters. (
See “modem” on page 71.
).
• Data interface clocking. (
See “clkmode” on page 55.
).
• Data framing. (
See “fstruct” on page 59.
).
