IRIG-B TTL TO RS485 Converter
SPC - INS - 1010
-
Signals & Systems India Private Limited
The IRIG-B TTL signal is a time synchronization protocol that can be transmitted up to 50m maximum using coaxial cable. So the relay which is to be received the IRIG-B TTL signal may be far away from the IRIG-B source. The relay may be not able to synchronize with the GPS. To avoid such an incident in the field, some of the relays have provision to receive IRIG-B RS485 signal. The IRIG-B RS485 signal can able travel up to 1200m without any booster. All Time source equipment may not be supplied with IRIG-B RS485 signal output. The converter will act as a bridge between GPS Time source and Relays for time synchronization.

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.

Compact Protocol Analyzer
LE-1500R
-
"LE-1500R" is a protocol analyzer (line monitor) dedicated for asynchronous communication monitoring with affordable pricing. LE-1500R can run as a stand- alone by the internal battery for long time and can be remotely controled by a PC or a smart phone via Wi-Fi (Wi-Fi function is available only in USA, Canada, Japan, and EU). The analyzer has a TTL measurement port (which supports UART communication) as its standard port besides RS-232C, RS-422, and RS-485. It can monitor communication data of max 500Kbps for up to 32MB (8,000,000 data) in real time and also can execute a simulation testing of send/receive data. It also has a BERT function (which is not equipped with the analyzers of this pricing level) as its standard function. The correct time stamp, the measurement of idel time (which are the difficult for other software analyzers), and the capturing ability (without missing data) are the best options for trouble shooting and development test of a communication sytem which requires a reliablity.
