2-Series Integrated Dual Bus Control System
Crestron
AV2 & PRO2
2 Series Ports
A number of ports are provided on the front and rear panels of the 2 Series integrated
control systems. Refer to the description of each below.
COMPUTER
Computer Connectors
FRONT PANEL
REAR PANEL
These DB9F connectors (one on front panel and one on rear) are used when
programming with a PC. Each port is modem compatible. The modem and/or PC
program cable are not included.

24VDC 50W
24 Y Z G
A 4-wire network connector resides on the rear panel. This connector (typical
Crestron network port labeled 24 Y Z G) is used for expansion to Cresnet and
SmarTouch peripherals. Depending on the expansion slot load, there is a 50 W
maximum load rating. Refer to "Network Wiring" on page 14 for details.

On the rear panel there are six software programmable bidirectional serial ports for
RS-232, RS-422, or RS-485 communication with hardware and software
handshaking. Speeds are rated up to 115,200 bps. Ports C, D, E, and F are Cresnet
Accelerator ready. The Cresnet Accelerator effectively increases the network speed,
fan-out, and device addresses by a factor of 8 for each Poll Accelerator added to the
system.
NOTE:
The pinout of each 9-pin port is non-standard (refer to the table after these
notes, titled "Non-Standard COM Pinout"); it contains RS-422 pins in addition to
RS-232. This may result in a conflict with some equipment and therefore all nine
pins should not be used. Only the required pins for each communication type should
be connected.
NOTE:
Data Set Ready (DSR) and Data Terminal Ready (DTR) are not supported.
NOTE:
To support RS-485, tie pin 1 (RXD-) to pin 9 (TXD-) and pin 4 (TXD+) to
pin 6 (RXD+) in the cable (refer to the table after this note, titled "COM Pinout to
RS-485 Bus".
