FLM-1 Installation & Operation Manual Chapter 1 - Introduction Front Panel The front panel provides control over the operation of the unit. The LEDs provide real-time indications related to the operation and status of the unit. Two push-button switches allow test loopbacks for the FLM-1 diagnostics. For details, see Chapter 3, “Operation” and Chapter 4, “Troubleshooting and Diagnostics”. Rear Panel The rear panel of the unit allows access to interface and power connections.
FLM-1 Installation & Operation Manual Note Chapter 1 - Introduction 1. The distortion refers to the duty cycle and not to the voltage level. 2. Whenever possible (if the number of channels is less than or equal to 6) it is recommended to operate FLM-1 in the six-channel mode, which results in less distortion. 1.4 Technical Specifications Subchannels Transmission format Asynchronous Data rate Optical interface: up to 38.4 kbps Electrical interface: up to 19.

FLM-1 Installation & Operation Manual Chapter 2 - Installation and Setup RJ-45 Connectors Twelve RJ-45 modular jacks on the rear panel (see Figures 2-5 to 2-7) each support a single channel. Pinout for this option is given in Appendix B. The six-channel operation with full duplex data and transmitting control signals end-to-end requires special cables (not provided by RAD).
FLM-1 Installation & Operation Manual Chapter 2 - Installation and Setup Connecting the Main Channel 4-wire Version - Terminal Block A 5-screw terminal block is located at the rear panel (see Figures 2-2 and 2-7). Five wires, marked TX-A, TX-B, RX-A, RX-B and CHASSIS GND connect transmit and receive wires and the cable shield (if available). To connect the main link with the terminal block, proceed as follows: 1. Connect TX connectors at the local unit to RX connectors at the opposite unit. 2.
Chapter 2 - Installation and Setup Warning FLM-1 Installation & Operation Manual Before connecting power to the unit, verify that the socket outlet is provided with a protective earth contact. If you are using an extension cord (power cable) make sure it is grounded as well. Interrupting the protective (grounding) conductor (inside or outside the unit), or disconnecting the protective earth terminal can make this unit dangerous.
Chapter 3 Operating Instructions 3.1 General This chapter covers: • A list of controls and indicators together with their functions. • An operating procedure covering power turn-on, operating instructions, and power turn-off. • Information on strapping. Before operating FLM-1, complete all the installation procedures described in Chapter 2. 3.2 Front Panel Indicators and Switches The FLM-1 front panel is shown in Figure 3-1.
FLM-1 Installation & Operation Manual Chapter 3 - Operation Table 3-1 lists the functions of the FLM-1 indicators and switches. Table 3-1 FLM-1 Indicators and Switches Identification No Name Type Function 1 POWER LED Indicator (green) Lights up when the unit is powered. 2 TEST LED Indicator (yellow) Lights up when either local or remote unit is performing a loopback test. 3 SYNC LOSS LOCAL LED Indicator (red) Lights up when synchronization is lost at the local unit.
Chapter 4 Troubleshooting and Diagnostics 4.1 Frequently Asked Question Question: How can I connect six pairs of DTEs for transferring Data and Control Signals (RTS to DCD) end-to-end? Answer: First set the jumper marked “SELECT 6 OR 12 CHANNELS” to the “12” position. Now FLM-1 passes 12 pairs of signals (TD and RD of channels 1 to 6 and secondary TD and RD of channels 7 to 12) end-to-end.
Chapter 4 - Troubleshooting and Diagnostics Local Loopback FLM-1 Installation & Operation Manual When FLM-1 performs a local loopback, the data from the local transmitter is looped back to the local receiver at the digital level, thus checking all local digital circuitry for proper operation. To activate the test, press the LLB push button located on the front panel. If the local unit is operating properly, the yellow TEST indicator should light up and all other indicators should be OFF.
FLM-1 Installation & Operation Manual Chapter 4 - Troubleshooting and Diagnostics Table 4-1 Fault Isolation and Troubleshooting Symptom All front panel indicators are OFF Action 1. Check that power is supplied to the unit. 2. Check the fuse inside the AC receptacle on the rear panel and replace it with a new one. 3. Replace the unit. The fault is probably in the unit's power supply circuits. LOCAL SYNC LOSS LED is ON 1. Perform an LLB test as described in Section 4-1.
