COM ports, RS-232 only (see figure 18,
B
on page18)
— Use COM ports for serial control of a display or other
device and to receive status messages from the connected
devices. These ports can send commands from a driver
file. These ports support only RS-232 communication.
MLCPlus84 Series Serial protocol:
• 300 to 115200 baud (9600 baud = default)
• 8 (default) or 7 data bits
• 1 (default) or 2 stop bits
• No parity (default), even, or odd parity
• Flow control support (default = none): software-only
(XON, XOFF)
Use the following diagram as a wiring guide to cable
the controller to other devices.

Figure 21. Wiring COM ports for Serial Control
For bidirectional serial communication, the transmit, ground, and receive pins must be
wired at both the controller and the other device. Each projector or other device may
require different wiring. For details, see the manual for that equipment or read the Extron
device driver communication sheet, which is included with the drivers.
NOTE: Maximum distances between the MLCPlus84 and the device being
controlled may vary up to 200 feet (61 m). Factors such as cable gauge, baud
rates, environment, and output levels (from the MLCPlus84 and the device being
controlled) all affect transmission distance.
