HX7+ ASD Installation and Operation Manual 33
HX7+ ASD Control
The Control PCB (Figure 8) serves as the primary control source for the HX7+ ASD. The Control PCB
receives input from the Terminal Board (see Figure 8 on pg. 32), an Option Card, RS232/RS485
Communications, or the keypad.
The Control PCB has been enhanced to support two additional functions: Multiple Protocol
Communications and the ability to communicate in either half- or full-duplex modes.
Using the optional multiple-protocol communications interface; the ASD-NANOCOM, the Control
PCB may be configured for the type of communications protocol being received and respond
appropriately to the sending device. The ASD-NANOCOM connects to the J4 and J5 connectors
(see Figure 8). Jumper PCB (P/N 55365) is required at the J4 connector if not using the ASD-
NANOCOM.
The ASD-NANOCOM must be setup to support the desired communications protocol via Program
Communication Communication Settings. Consult the ASD-NANOCOM User Manual
(P/N 10572-1.000-000) for a complete listing of the setup requirements.
Half or Full duplex communications is available when using RS232/RS485 communications. The
jumpers at the JP1 and the JP2 connectors may be moved from one position to the other to facilitate
either half- or full-duplex operation. If no jumpers are used the system will operate in the full duplex
mode.

NANOCOM.
