Loop and Remote Loop Operation Mode

Loop

In this state, the device performs a loop on the twisted pair through the Line Interface, as well as another loop from AIR RX to AIR TX.

LocalLoopback

The device on the side of the technician is in LOOP state when dipswitch “1” is “ON” and Dipswitch “2” is “OFF” (for 4 E1: Dipswitch 3 ON & 4 OFF).

RemoteLoop

The device on the opposite side turns to loop state by being controlled from the near device (Master) – dipswitch “2” in “ON” and dipswitch “1” is “OFF” (for 4E1: Dipswitch 4 ON and Dipswitch 3 OFF).

In the opposite device (Slave), both dipswitches – 1 and 2 – should be “OFF” (Normal)(for 4E1 Dipswitches 3&4 OFF).

When turning off the Master, the Slave exits Loop state.

When the Slave does not receive an optical signal for the duration of 0.8 seconds, it exits Loop state. In this situation, when electronic Reset was not performed on Master, the technician should shut off the device and reactivate it.

Heating

All our TereScope systems are designed with our special internal air circulation feature, based on dissipation of the power supply heat. This prevents the formation of condensation on the lenses under all weather conditions without the need for additional heating at low temperatures

In spite of the aforesaid, an optional front window with the heating system can be ordered separately (p/n TSX000-HEAT for a link). We recommend this solution only for extremely adverse weather conditions such as heavy snow with strong wind or high humidity.

The dissipated heat of about 25W creates a differential of about 10o between the glass and the environment. The Heating is controlled by a Switching and control circuit
