Bidirectional Control and Communication Connections and Features
c
COM1 through COM6 RS-232 ports (-5 VDC to +5 VDC) and
d
COM7 and COM8 RS-232/RS-422/RS-485 ports (-5 VDC to +5 VDC) — 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.
IPCP 505 serial protocol:
• 300 to 115200 baud (9600 baud = default)
• 8 (default) or 7 data bits
• 1 (default) or 2 stop bits
• No parity (default), or even or odd parity
• Flow control support
• COM1 - COM6: software-only (XON, XOFF)
• COM7 and COM8:
hardware and software
Use the following diagram as a wiring guide to
cable the IPCP to other devices.

Figure 8. Wiring for Serial Control
For bidirectional serial communication, the transmit, ground, and receive pins must be
wired at both the IPCP 505 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.
NOTE: Maximum distances between the IPCP 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 IPCP and the device being controlled) all
affect transmission distance. Distances of about 50 feet (15 m) are typically not a
problem. In some cases the IPCP may be capable of transmitting and controlling
a given device via RS-232 up to 250 feet (76 m) away, but the RS-232 response
levels of that device may be too low for the IPCP to detect.

TIP:
Comm-Link (CTL
and CTLP) cable,
shown at left, is
recommended
for these
connections. For
best results and
to avoid short
circuits, use
shielded wires
or wires insulat-
ed using heat
shrink (instead
of bare wires) for
the common/
drain wires.
