Crestron AV2 & PRO2 2-Series Integrated Dual Bus Control System

RXD (COM A - F)

These LEDs illuminate during reception of data from serial devices attached to the

respective COM ports.

TXD (COM A - F)

These LEDs illuminate during transmission of data to serial devices attached to the

respective COM ports.

RTS (COM A - F)

These LEDs illuminate to reflect the state of the RTS pin on the respective COM

port. An illuminated LED means that the RTS line is high. If no handshaking is

specified, the RTS line will be high and therefore, the associated LED is also high.

When RTS flow control is enabled, RTS indicates the unit is ready to receive data

from serial devices attached to the respective COM ports.

CTS (COM A - F)

These LEDs illuminate to reflect the state of the CTS pin on the respective COM

port. An illuminated LED means that the CTS line is high. When CTS flow control is

enabled, CTS indicates the serial devices on the respective COM ports are ready to

accept data from the unit.

IR – SERIAL (A - H)

These LEDs illuminate during activity on the respective IR/SERIAL lines.

INPUT – OUTPUT (1 - 8)

These LEDs illuminate when the input voltage thresholds for the respective I/O ports

are exceeded or when the output is active.

RELAY (1 - 8)

These LEDs illuminate when the respective relay is closed.

SLOT (1 - 3)

These LEDs illuminate when an expansion card is inserted into the respective slots.

These LEDs extinguish momentarily when data is sent to the card or received from

the card.

Reset Buttons

Two buttons are provided on the front panel of the 2 Series integrated control

systems. Refer to the description of each below.

HW-R

Pressing this button initiates system hardware reset. (Same effect as disconnecting

and reconnecting power.)

SW-R

Pressing this button in combination with the HW-R button performs a system restart

without loading the program (refer to “Troubleshooting Communications” on page

21). Pressing it alone momentarily while the system is running restarts the program.

PRO2 LCD Screen

The front panel of the PRO2 incorporates a reverse mode (yellow on black) LCD

screen, shown below. The screen contains two lines with up to 40 characters per line;

it is used to extend features and gain access to the system including the SIMPL

program. To the right of the display are four menu selection buttons. These buttons
