Mezzanine System
5033
System
ECM P/N 5033 provides eight channels of RS485 / RS422 I/O. The 110 ohm termination for each channel is enabled or disabled in software. Disabling termination saves power by eliminating unneeded or redundant termination. Speeds of up to 20 Mega bits per second are possible, but this design also features a 250K bits per second slower edge rate mode. The 250K bit mode is valuable when EMI is more of a concern and throughput is not important. All channels power up as inputs with the outputs disabled.

Dual Channel Multi-Band FM Tracking/Data Receiver In Modular Style Housing
LS-27-B
-
The Lumistar LS-27-B Modular Dual Channel Tri-Band Tracking and Data Receiver is Lumistar’s third generation of modular high performance FM Receivers. This wideband designs supports one or two independent channels of PCM with data rates up to 20Mbps. The unit includes both an optional FM demodulated output for PCM data, and standard programmable AM/linear AGC outputs for auto-tracking receivers. The design offers 8 IF Bandwidths and 8 Video Filters per channel for each receiver.AC coupling with a low pass filter is employed to ensure a high quality data link with long strings of NRZ-L ones or zeroes. The unit provides a software selectable 10 MHz reference I/O port forlocking local oscillators to a high precision external source or to arrange multiple units in a master/slave arrangement. The receiver’s control and status is achieved via Ethernet, USB or auto-switched RS-232 (or “4-wire” RS-485 in place of 232). When utilizing the RS-422 interface, multi-drop configurations can be accommodated.

Multiprotocol Transceivers
-
Analog Devices’ RS-232/RS-485 multiprotocol transceivers are the only parts in the market that allow protocol switching and allow for switching between half-/full-duplex operation and switching on/off termination resistors, both of which minimize physical user intervention when reconfiguring networks. Features include 3.3 V to 5 V operation, up to ±26 kV ESD, a logic supply pin, and small LFCSP packages. As large-scale computing applications typically require more protocols than the RS-232 and RS-485 protocols found in everyday applications, we support legacy protocols. These include V.28 (RS-232), V.35, RS-449, RS-530, RS-530-A, V.36, or X.21. Software-selectable protocol, cable termination, and data terminal equipment (DTE) or data communications equipment (DCE) configurations all provide convenient flexibility.
