 | HomeVision-Pro is mounted in an alarm-type enclosure. The steel, beige-colored
enclosure measures 14" x 13" x 3" (note that the photo above was taken with
an enclosure of 11.25” x 11.25” x 3.0”). |
| HomeVision-Pro contains three user-controllable serial ports. The primary serial
port is the same as on HomeVision. In addition, all the capabilities of two
HomeVision-Serial devices are built into HomeVision-Pro. You cannot use external
HomeVision-Serial devices with HomeVision-Pro. Therefore, the maximum number of serial
ports remains at four (three built into HomeVision-Pro, plus one on the
HomeVision-Phone/Serial device). |
| HomeVision-Pro also contains another serial port that will be dedicated to
special functions (the user cannot control it like the other serial ports). We are currently
considering how best to use this port. |
| HomeVision-Pro contains a USB-to-serial adapter. This can be used on the main
HomeVision-Pro serial port to connect to a PC USB port instead of a PC serial port. If you
don’t use the USB-to-serial adapter for this main port, it can be connected to one of
the additional serial ports HomeVision-Pro provides. |
| HomeVision-Pro contains four analog inputs. These provide the same capabilities
as the analog inputs on the Multifunction Expansion Board. When using HomeVision-Pro, you
can now have a total of 20 analog inputs (four on HomeVision-Pro plus 16 on two
Multifunction Expansion Boards). |
| HomeVision-Pro supports digital temperature sensors and has an improved drive
circuit. You no longer need a Multifunction Expansion Board (MFEB) to use the digital
temperature sensors (the MFEB digital temperature sensor interface is disabled when used
with HomeVision-Pro). The HomeVision-Pro drive circuit is improved over the one on the
MFEB, and allows driving longer cables. |
| HomeVision-Pro output Port A provides eight Single-Pole-Double-Throw (SPDT) power
relays. Relays are rated for 10Amps at 125VAC, 6Amps at 277VAC, and 5Amps at 100VDC.
|
| HomeVision-Pro input Port B contains switches to individually enable or disable
“pull-up” resistors. HomeVision contains pull-up resistors that make the inputs
go high when nothing is connected. This makes connecting “contact closure”
inputs easy. However, when connecting a voltage source, it is often necessary to add an
external resistor to overcome the built-in pullup resistor. The HomeVision-Pro switches
simplify connections by allowing you to disable the built-in pullup resistors instead of
adding external resistors. |
| HomeVision-Pro has an infrared receive input jack (in addition to the two
built-in infrared receivers standard on HomeVision). |
| The HomeVision-Pro infrared output is available at a terminal block as well as an
infrared output jack. |
| The HomeVision-Pro infrared output is a 12V signal instead of the 5V signal used
on HomeVision. It provides higher current capability and is easier to connect to some IR
distribution systems. |
| The built-in infrared emitter standard on HomeVision has been removed from
HomeVision-Pro. |
| HomeVision-Pro provides additional terminal block connection points for power,
ground, and other functions. There are a total of 60 terminal block positions. |
| The HomeVision-Pro battery is a standard coin type that can easily be replaced by
the user if needed. |
| HomeVision-Pro can connect directly to the Sylva input/output boards. Unlike
HomeVision, it does not require a Multifunction Expansion Board in order to connect to
these Sylva boards. |
| HomeVision-Pro has an enhanced memory architecture that allows the processor to
access more RAM than HomeVision. This makes it easier for HomeVision-Pro to provide
additional features in the future. |
| HomeVision-Pro will function slightly faster than HomeVision.
|
| HomeVision-Pro provides connectors and board space for a future expansion board
(to provide Ethernet functions as well as other capabilities). |
| Schedules created in the HomeVision software can be read by the HomeVision-Pro
software. |
| HomeVision-Pro requires a regulated 12VDC, 1.25A power supply. |
| HomeVision-Pro contains a total of 43 status LEDs to help you see exactly what is
happening. HomeVision-Pro does not contain a "user
LED" like HomeVision does. The HomeVision-Pro LEDs are:
 | 24 LEDs on each of the 24 digital I/O ports |
| One transmit and one receive LED on each of the 3 serial ports and the USB port |
| One digital temperature sensor status LED |
| One power indicator LED |
| Three X-10 status LEDs |
| Two infrared status LEDs |
| Four processor status LEDs |

Three ports. One supports RS-232 only. The
other two support RS-232, RS-485 half-duplex (two-wire mode), and RS-485 full-duplex
(four-wire mode). All support baud rates of 300, 600, 1200, 2400, 4800, 9600, 19200 and
57600. All use standard communication settings of 8 data bits, 1 start bit, 1 stop
bit, and no parity. |
