8. o radio and television reception The Model 1012AR has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart J of Part 15 of FCC rules which are designed to provide reasonable protection from such interference in a commercial installation However there is no guarantee that interfer ence will not occur in a particular installation If the Model 1012AR does cause interference to radio or television reception which can be determined by disconnecting the RS 232 interface the user is encour aged to try to correct the interference by one or more of the following measures moving the computing equipment away from the receiver re orienting the receiving antenna and or plugging the receiving equip ment into a different AC outlet such that the computing equipment and receiver are on different branches 1 2 SERVICE All warranty and non warranty repairs must be returned freight prepaid and insured to Patton Electronics All returns must have a Return Materials Authorization number on the outside of the shipping container This number may be obtained from Patton Electronics Technical Service at 301 975 1007 Packages received without an RMA number will not be accepted Patton Electronics technical staff is also available to answer any questions that might arise concerning the installation or use of your Model 1012AR Technical Service hours 8AM to 5PM EST Monday through
9. tly the Model 1012AR may be used to extend RS 232 TIA 561 distances in environments where connected equipment is located in different build ings The 1012AR uses the latest in bi directional clamping transient suppressors to protect itself and connected equipment against harmful transient surges These suppressors can dissipate 600W per wire at 1 0 mS Response times are typically 1 0 pS from 0 to the nominal breakdown level of 6 8 volts 3 0 CONFIGURATION The Model 1012AR is pre configured at the factory to work in mul tipoint applications and in point to point applications that use hardware flow control These are the vast majority of applications that call for the Model 1012AR Therefore you will normally have no need to re configure the Model 1012AR it will be strictly plug and play The only user modifiable setting on the Model 1012AR is the RTS control strap The RTS control strap setting determines how its trans mitter i e carrier is activated When the RST control strap is ON installed on the pins the transmitter is enabled by activating RTS RJ 45 pin 8 This is the factory setting When its strap is OFF removed from the pins the 1012AR s transmitter is constantly on If your application requires the transmitter to be constantly on i e hard ware flow control disabled follow the instructions below Step 1 Opening the Case To open the Model 1012AR s case insert the blade of a small flat head scr
