10
The Smart Remote is equipped with a triple output Universal Switching Power Supply rated at
5vdc @ 4A, +12dc @ 2A, -12vdc @ 0.2A. The last output is not used. No voltage adjustments
are required. The power switch of the Main Unit is part of an integrated AC receptacle. A separate
line filter unit is mounted internally. Overload protection is provided by fuses (2) rated at 250 VAC
@ 500mA (slow blow).
NOTE: Connect the unit only to a properly rated supply circuit.
To minimize the risk of shock, always use a grounded (earth) power cord.
It is recommended that the AC cord be disconnected from the unit when the unit is being
serviced
4. Communications
Communications between the Main Unit and the Smart Remote is through an RS-422 interface at
a data rate of 115 Kbps. A standard DB9 male-male RS-422 cable is needed, with a maximum
length not exceeding 1 Km (pins 3,8 and 7,2 are used). A maximum of four (4) Ultimatte-9 and/or
Ultimatte-400 Main Units can be connected to one Smart Remote.
The Smart Remote is software configured to be the Master with up to four (4) Ultimatte-9/
Ultimatte-400 Main Unit combinations as slaves. Only the Master can initiate a message
exchange.
An RS-232 port is also available (DB9 female connector), which allows the Smart Remote to be
connected to a computer. When connected to a computer, this port is used for upgrading the
unit's operating software and saving and recalling setup parameters.
Upgrades can be downloaded from an external computer directly into Flash memory through the
RS-232 port.
