1.0 W ARRANTY INFORMA TION Patton Electronics warrants all Model 1080A Series components to be free from defects, and will—at our option—repair or replace the product should it fail within one year from the first date of shipment.
2.0 GENERAL INFORMA TION Thank you for your purchase of this Patton Electronics product. This product has been thoroughly inspected by Patton's qualified technicians. If any questions or problems arise during installation or use of this product, please do not hesitate to contact Patton Electronics T echnical Support at (301) 975-1007.
Each Model 1080A Series SRM has three sets of eight switches, yielding 24 total DIP switches. The three sets will be referred to as S1, S2 and S3. As Figure 2 shows, the orientation of all DIP switches is the same with respect to “ON” and “OFF” positions.
Switch S1-8: Carrier Control Method The setting for switch S1-8 determines whether the carrier is “constantly on” or “controlled by RTS”. This setting allows for operation in switched carrier , multipoint and/or hardware handshaking applications.
3.4 CONFIGURA TION SWITCH SET “S3” The DIP switches on S3 set the anti-stream control, local loopback enable, remote loopback enable and receive (input) impedance levels for the Model 1080A Series. Factory default positions of Switch S3 are shown in the table below .
Switch S3-6: RS-232 Initiation of Remote Loopback T est The setting for switch S3-6 determines whether or not the Model 1080A Series’ remote digital loopback test can be initiated by raising pin 21 on the RS-232 interface.
4.1.1 T wo-Wire Cable Connection Via RJ-45 A. The RJ-45 jack on a Model 1080A Series Short Range Modem is prewired for a standard TELCO wiring environment.
4.2.1 Four-Wire Cable Connection Via RJ-45 A. The RJ-45 jack on a Model 1080A/1080A-64 Short Range Modem is prewired for a standard TELCO wiring environment.
4.3 FOUR-WIRE, MUL TIPOINT INST ALLA TION Multipoint operation involves the connection of several terminals to one host port. In such an application, one local Model 1080A/1080A-64 is used as a master unit, and it is connected to several remote Model 1080A/1080A-64s that are acting as slaves.
5.1.4 The “Error” Indicators The “Error” indicator LED has three functions: A. When the 1080A Series unit is in test mode (green “T est” LED is lit), the error LED glows red when bit errors occur . B. When not in test mode (green “T est” LED is off), the error LED is used to indicate an RTS streaming condition.
5.1.4.2 Reading The T est A. If line quality is good, “Error” LED on local modem will not light and “CD” LED will be red. On remote modem “Error” LED will not light and “CD” LED will light green.
A. Activate RDL. This may be done in two ways: First, by moving the front panel toggle switch UP to "Remote". Second, by raising pin 21 on the RS-232 interface (Note: Make sure DIP switch S3-6 is ON; and DIP switch S2-6 is OFF). B. Perform a BER (bit error rate) test on the system.
