DAVIS 7626 Installation Manual page 6

The components of the board are:
• Solar Power Input (used on #7627 models only) — Connects the solar panel on the
cover of the enclosure to the repeater board.
• AC Adapter Socket — Used to connect the optional 110 volt AC power adapter to
the repeater board. The AC adapter is available primarily for AC-powered (#7626)
repeaters but is available for solar power models as well. You can purchase an optional
AC power adapter (#6625) for solar power models as an alternate source of power.
Note: Using the AC power adapter with a solar power model disables the solar-power charging circuit and
makes the AC adapter the main source of power.
• Battery Socket — Used to back up solar or AC power when the provided 3-volt
lithium battery is inserted.
• Transmitter DIP Switches — An eight-position switch used to set the transmitter IDs
the repeater listens to and repeats. The repeater comes with station ID 1 turned on and
all other transmitter IDs are turned off.
• Repeater DIP Switches —The first three positions in this four-position switch are
used to give the repeater a unique ID. All three positions are initially in the off
position, giving the repeater the ID of A.
Note: All station IDs are identified using numbers 1-8, and repeater IDs are identified using letters A-H so that
they are easily identifiable from each other.
• Repeater Test Switch — The fourth position in the four-position Repeater DIP switch
enables the TX and STAT LEDs to observe repeater and communication behavior.
Initially this switch is in the off position.
• First In Chain Jumper — A three-pin header
that can enable a repeater with a unique ID other
than A to become the first repeater in a chain if
two or more repeater chains are required in a
given network. See "First in Chain Applications"
on page 41 for more information.
Note: Any repeater with ID A or any repeater in a standard single-chain network should have the first in chain
jumper left in the default position (pictured above).
• TX LED — This green LED verifies transmission from the repeater to a receiver or
used in correlation with the STAT LED, displays error codes related to repeater
communication. See "Repeater Troubleshooting Error Codes" on page 36 for more
information.
• STAT (Status) LED — This multi-colored LED describes the status of the radio
packets received from stations or other repeaters or, used in correlation with the TX
LED, displays error codes related to repeater communication. See "Repeater
Troubleshooting Error Codes" on page 36 for more information.
Tools for Setup
The following tools and materials are required to set up and install the wireless repeater:
