Codan 5700 Series C-Band Transceiver Operation 5700

Codan 5700 Series C-Band Transceiver Operation

5700 Connectors (1) • DC POWER connector – 48 V DC (37 -76 V), floating or groundreferenced, via a 5 -way ‘MS’ plug • IF N-type connectors – Use only quality N-plugs. Sockets are always 50 -ohms • The 19 -way MONITOR / CONTROL (M&C) connector – M&C has dry contact & serial data facilities

5700 Connectors (2) • SSPA DC / CONTROL connector • RF N-type connectors – Use only quality N-plugs. Sockets are always 50 -ohms • The separate LNA DC / ALARM connector – LNA socket provides 15 V at up to 400 m. A. A cable is available for Maxtech LNA’s with form ‘A’ alarm option

5700 Controls (1) • POWER OFF / STANDBY / ON switch When in STANDBY, only the reference oscillator and M&C sections operate. The 5700 can be turned ON by the control-panel switch, a serial data command or a remote contact closure. • SSPA - INHIBIT / REMOTE / ACTIVATE The Control Panel switch allows local activation or de-activation of the SSPA for maintenance, and for re -setting alarms. Remote control is also possible by serial data command or a dry-contact closure

5700 Controls (2) • Factory default switch settings: The highlighted switch positions correspond to: RS 232 interface, ASCII protocol, 9600 bits/sec. , 8 data bits, no parity. The TERM and PACKET ADDRESS switch settings are not relevant.

SSPA • No controls or adjustments on the module • Choice of WR 137 (CPRG flange) or N-type output – 5 to 40 W only – 60 and 120 W SSPA’s only have WR 137 CPRG flange • Activating / inhibiting is controlled by the 5700 Converter • Gain vs. temperature compensation & system gain adjustment is also within the converter.

High Power SSPA • Controls or adjustments in the module not necessary • WR 137 (CPRG flange) output for superior performance • Activating / inhibiting is controlled by the 5700 Converter • Gain vs. temperature compensation & system gain adjustment is within the SSPA.

Getting Started (1) • Connecting a basic low power system: AC Power Tx RF 48 V DC 5582 Power Supply 5700 Converter M&C 5560, 5570 or PC Power / Control Tx RF O/P 57 XX SSPA Rx RF LNA

Getting Started (2) • Connecting a basic High Power system: AC Power 48 V DC Tx RF 5560, 5570 or PC M&C 5700 Converter Power / Control Tx RF O/P 57 XX SSPA Rx RF LNA

Getting Started (3) • Grounding of modules – Ensure the SSPA, Converter and 5582 Power Supply are suitably grounded to a good-quality lightning stake – Ensure the antenna is also suitably grounded to a good-quality lightning earth stake

5582 Mains Power Supply • 115/230 V selection • Simple linear power supply design • 5 A or 2. 5 A 20 x 5 mm delay fuse (‘T’ type) • Provide a PROTECTIVE GROUND • Unit is UNREGULATED • Includes 48 V ‘on’ LED

Powering Up • Select SSPA INHIBIT. • Turn on the mains power. • Turn on the 5700. • Connect the hand-held controller or personal computer to configure the transceivers perameters. • If you have a load connected, you can also turn on (ACTIVATE) the SSPA.

Programming the 5700 (1) • For PC operation, set the 5700 ‘DIP’ switches to match your terminal settings. • Establish PC-5700 communications via a spare COM port on your PC & the 19 -way M&C connector on the 5700. • You can use the Windows ‘Hyper Terminal’ facility, ‘Pro. Comm’ or similar communications software - no need to buy special software !

Programming the 5700 (2) • The Set Parameter commands and Fault Enable commands must correctly reflect your actual hardware configuration • The Logging commands determine what information (if any) is sent to the terminal about the 5700 operating status.

Programming the 5700 (3) • Certain parameters are essential for correct RF operation • Others are required for remote control of the RF system

Programming the 5700 (4) • Parameters may be set from the configuration PC terminal or the 5570 Remote Controller Unit • Certain parameters may be set from the 5560 Hand-Held controller

Alarms • Some alarm states will inhibit transmission: CONVERTER, SSPA, & TEMP (SSPA case > 75 C) • A FAN or SSPA alarm must be reset by selecting SSPA INHIBIT first, then re-activating the SSPA. • An LNA alarm due to open-circuit will reset automatically when the LNA is connected. • An LNA alarm due to current exceeding 250 m. A from the N-connector will shut-down the LNA supply. To reset, switch the 5700 to STAND-BY then back ON.

5560 Hand-Held Controller • Super-convenient set-up tool • Easily fits in technician’s tool box • Programs all operating parameters of the 5700 with a simple, intuitive menu • Simply ensure ‘RS 232’ and ‘ASCII’ are selected on the front of the 5700, and plug in the 5560.

5570 Remote Controller • Indoor mount, 2 RU high • Provides full M&C of the transceiver. – Operating peratmeters – Fault monitoring • Operates with either RS 232 or RS 422 • 50 m Cable provided as standard – Optional lengths available

More on Serial Control. . . • Illegal commands Certain hardware configurations will prohibit the use of certain serial commands. • Output Commands Wide range of commands to invite a response from the 5700 of a single parameter or operating state. • Packet Protocol Variety of packet protocols to suit common Network Management Systems.

Integrating the 5700 with your station design • Overall transmit gain is adjustable from 35 to 65 d. B (nom) for 60/120 W systems, 44 to 74 d. B (nom. ) for 10/20/30/40 W systems, or 41 to 71 d. B (nom. ) for 5 W systems. • Overall receive gain is adjustable from 70 to 100 d. B (nom. ), assuming an LNA gain of 55 d. B.
