ISC RSS 0 This device complies with Part of the FCC Rules. Operation is subject to the following two conditions: () This device may not cause harmful interference, and () this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by BENTEK SYSTEMS LTD will void the user's authority to operate the equipment. This product is intended for fixed installation applications. In order to comply with FCC/ISC adopted RF exposure requirements, installation of this transmitter system's antennas must be performed in a manner that will provide at least foot(m) clearance from the front radiating aperture to any user or member of the public.

Configuring I/O Module Addresses Module Address Selection Switch Each pair of I/O modules, such as the AI and the AO, must share a unique module address. Once a module address has been assigned to a pair of I/O modules, that module address may not be used on any other pair of I/O modules or the same radio pair. Available addresses are numbers through. If module addresses conflict, or are improperly set within a connected group, an indication will be given by the LED (see section below). The Transceivers are designed to operate as matched pairs, and are factory programmed. Manual address configuration is not required for the transceiver units. Status LED's Power LED Status LED RF LED Input / Output Power LED indicates presence of power to the device. It is ON when power is present and OFF when there is no power. When flashing rapidly it indicates an "Internal Error" or a "Module Type Mismatch" A Module Type Mismatch occurs when the Module Address selection for two different modules (i.e. one () discrete module and one () analog module) are set to the same address, or two () pairs of modules are sharing the same address. When Status LED is ON steady, Module Address settings are OK. Flashes once every two seconds when there is no RF Link Flashes rapidly when signal strength is marginal (see RSSI Table) ON steady indicates an exceptionally strong RF Link. Most systems will flash occasionally indicating the presence of intermittent interference in the area OFF means that the discrete input or output is Open ON means that the discrete input or output is Closed RSSI Troubleshooting RSSI (Received Signal Strength Indicator) is measured using a DC Voltmeter between the test point and power supply ground. Test point is accessed by inserting positive meter probe into the RSSI hole on the face of the. The following RSSI table may be used to test the Receive Signal Strength of the. The ideal voltage that should be read from the RSSI test point is.vdc. This represents a 90dB signal loss and typically indicates that the radio has 0dB fade margin left until loss of link. It is recommended that the radios be set up with no less than 0dB margin. DC Volts RSSI vs DC Voltage.00.00.00.00 0.00 0 0 00 90 0 0 0 Signal Loss (db) Version V.0 for
