MegaPower TM 48+
RS232 Communications
The RS232 section (PC icon) of the MegaPower 48+ patch panel consists of eight RJ45 receptacles and one DB9
receptacle.
• Cable required: modular eight conductor cable, cable distance (7 or 14 feet) and plug dependent on application.
• Accessories: wall-mount keyboard matrix interface (MP-KMI) and wall-mount eight pin terminal box. Box can be
single or dual mount dependent on application.
• Additional Cable: 18 AWG, three-wire, shielded cable. Maximum cable distance of 1000 feet (305m).
RS232 Keyboard Connections
The MegaPower 48+ can utilize any of the following six keyboards: ADCC1100, ADCC0200, ADCC0300, AD2079,
AD2088, and ADTTE Touch Tracker.
ADCC1100
ADCC1100 provides the user with the largest features set, including flexible macro programming and system partitioning
with smart card access control and user management. The ADCC1100 is connected to the MegaPower 48+ patch panel
by a seven foot modular cable with RJ45 plugs, and a MP-KMI keyboard matrix interface. Power to the keyboard is
provided by a transformer connected to the MP-KMI. For connections greater than seven feet, an additional MP-KMI is
used with 3-wire, 18 AWG shielded cable. Maximum cable length = 1000 feet (305m). See Drawing 14, Page 25 for a
typical connection using the ADCC1100 keyboard.
ADCC0200 and ADCC0300
The ADCC0200 and ADCC0300 keyboards are connected to the MegaPower 48+ patch panel by a seven foot modular
cable with RJ45 plugs, and a MP-KMI keyboard matrix interface. Power to the keyboard is provided by a transformer
connected to the MP-KMI. For connections greater than seven feet, an additional MP-KMI is used with 3-wire, 18 AWG
shielded cable. Maximum cable length = 1000 feet (305m). See Drawing 15, Page 26 for a typical connection using the
ADCC0200 keyboard.
AD2079 and AD2088
The AD2079 and AD2088 keyboards are connected to the MegaPower 48+ patch panel by a seven foot modular cable
with RJ45 plugs, and a dual 8-pin wall mount terminal box. Power to the keyboard is provided by a transformer connected
to the terminal box. For connections greater than seven feet, an additional single 8-pin terminal box is used with 3-wire,
18 AWG shielded cable. Maximum cable length = 1000 feet (305m). See Drawing 16, Page 27 for a typical connection
using the AD2088 keyboard.
ADTTE Touch Tracker
The ADTTE Touch Tracker keyboard connects to an EIM module via an 8 conductor, 14 foot modular cable with RJ45
plugs. MegaPower 48+ RS232 ports connect to the EIM module via an 8 conductor cable with an RJ45 plug at one end,
and a DB9M connector at the other end. Power is provided to the keyboard via a transformer connected to the EIM
module via a 5 pin screw terminal connector. For connections greater than 14 feet, two single 8-pin wall mount terminal
boxes are used with the EIM module and 3-wire, 18 AWG shielded cable. Maximum cable length = 1000 feet (305m).
See Drawing 17, Page 28 for a typical connection using the ADTTE keyboard.
Port Expander
An RS232 port with keyboard device type assignment can be connected to up to four keyboards through the use of the
AD2081 Port Expander. The RS232 port is connected to an RJ45 CPU input receptacle on the Port Expander via a
seven foot modular cable with RJ45 plugs. The keyboards are then wired from any of the four Port Expander output
ports using the configurations discussed in the section
RS-232 Keyboard Connections above . See Drawing 18, Page
29 for a typical connection using the AD2081 Port Expander.
