2.2 DESCRIPTION

The Model 1075 KiloModem II X.21 Short Range Modem supports synchronous data rates of 32, 56 and 64 Kbps. Synchronous transmit clock options are internal, external and receive recover clock. Deriving power from a 9V DC wall-mount transformer, the Model 1075 supports extended distances to 6 miles (9.7km) over 2 unconditioned twisted pairs.

The Model 1075 incorporates two V.54 test modes (local analog loop and remote digital loop) that are activated by a tiny front panel switch. In addition, a built-in V.52 Bit Error Test (BER) test generator that outputs 511 and 511E bit patterns can also be controlled by a switch on the case. Six LED indicators monitor transmit data, receive data, control, indication, test mode (TM) and Error Status (ER). For protection against ground loops and transient surges, the Model 1075 incorporates both isolation transformers and Silicon Avalanche Diode surge suppressors.

Housed in a miniature ABS plastic case, the Model 1075 comes equipped with a female DB-15 connector and a choice of twisted pair interfaces (RJ-11 jack or RJ-45 jack).

3.0 CONFIGURATION

The Model 1075 is easy to install and is ruggedly designed for excellent reliability. The following instructions will help you to properly configure the Model 1075.

3.1 CONFIGURATION SWITCHES

The Model 1075 uses a unique set of 16 external mini DIP switches that allow configuration to wide range of applications. The 16 external switches are grouped into two eight-switch sets, and are externally accessible from the underside of the Model 1075 (See Figure 1).
