Connections for Cable Distance of Seven Feet or Less
For switching system connections where keyboard-to-system cable distance is seven feet or less,
make the following connections using the jumpers included with the dual terminal block
After connecting the jumpers, connect one of the seven foot modular cables from the J2 (system)
jack of the dual terminal block, to the appropriate RS-232 port on the switching system. Connect
the other seven foot modular cable from the J1(keyboard) jack of the dual terminal block, to the
RJ-45 jack of the keyboard.
Connections for Cable Distance of Greater than Seven Feet
For switching system connections where keyboard-to-system cable distance is greater than seven
feet, the following components are required.
• Dual terminal block supplied with the AD2089
• A three-wire, shielded, 18 AWG cable supplied by the installer
• Single terminal block supplied with the AD2089
Use the three-wire cable to connect the keyboard and switching system terminal blocks. The
following table provides the connection points
After connecting the three-wire cable to the respective terminal blocks, connect one of the seven
foot modular cables supplied with the AD2089 from the J1(keyboard) jack of the dual terminal
block to the RJ-45 jack of the keyboard. Connect the other seven foot modular cable from the RJ-
45 jack of the single terminal block to the appropriate RS-232 port on the switching system.
Power Connections
Depending on national and local electrical requirements, the AD2089 is supplied with either a 120
VAC or a 230 VAC transformer. The 230 VAC transformer is supplied with a Euro-style IEC 320
type inlet. An appropriate detachable cord should be connected between the IEC 320 inlet and the
power source.
Connect the output leads from the wall transformer to screws 1 and 8 on the J1(keyboard) side of
the dual terminal block. All power to the AD2089 is supplied from this connection.
Note
Typical system and test connections are illustrated in Appendix C of this manual.
