ACCES Remote Distributed I/O Connectivity Options

EVERYTHING YOU NEED TO KNOW ABOUT YOUR OPTIONS 

WIRELESS

WM – includes a Wireless transceiver set. On the computer side, the Wireless module is powered by a wall adapter and plugs directly into an RS-232 port. These can be configured in a number of ways including 900MHz or 2.4GHz models. It includes a wire antenna, and no software is needed, thus making the Wireless link transparent to the user. On the Remote side, the unit has a Wireless transceiver installed in the lid of the protective metal enclosure which is then wired into the I/O Pod. One AC/DC supply is included with this which plugs into 115VAC and powers all the electronics of the I/O and the Wireless module. The unit ships with a power cable and DB9 connector to plug into the DC output of the supply. Alternately, if no AC power is available at the remote site, a battery can be purchased instead of the AC/DC supply. The Wireless version is handy for systems where you need to add a remote alarm or pick up a contact closure at some distance from a PC, without running any wires. Different ranges are possible with different antennas, from a couple-hundred feet up to 22 miles with a clear line of site. A Spread-Spectrum un-licensed radio set is used with a frequency hopping feature for higher reliability.

USB

U – is packaged for connection to a USB port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board. Communications with the host computer are accomplished via our USB-485 converters (Single Port USB to RS-232, RS-422, and RS-485 Serial Adapters) to  to a cable wired up to the serial data screw terminals on the board.

STANDARD RS-232

S – is packaged for connection to an RS-232 port via an RS-232 to RS-485 converter. This solution also uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board.

ETHERNET

E – is packaged for connection to a Ethernet port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the board. Communications with the host computer are accomplished via our ethernet to 485 module wired directly to the serial data screw terminals on the board.
