Teledyne LeCroy Frontline STA-422/485 Serialtest Async RS-232/485 Protocol Analyzer

To keep pace with advances in technology, the tried and true Serialtest analyzer has been upgraded to support the new "RS-422/485 ComProbe". Most new laptops and PCs do not have PCMCIA interfaces and the PC industry has migrated towards USB ports. To help our customers monitor asynchronous serial communications via their PC's USB port, Frontline has introduced its new RS-422/485 ComProbe II. This new device plugs into a PC's USB port and has screw terminal connectors to tap into the RS-422/485 circuit.

The RS-422/485 ComProbe monitors and captures Asynchronous RS-422/485 communications. It does not lose timing and control signal information. With this new interface, Frontline has made its Serialtest analyzer more rugged, easier to use, portable and transportable. It allows you to spend more time doing your real job.

I/O Settings

The new RS-422/485 ComProbe allows the user plenty of options for monitoring various serial communication setups. The I/O Settings dialog allows the user to configure the setup.

The RS-422/485 ComProbe supports data rates up to 921.6Kbps. The user can pick one of the standard rates in the drop down box in the I/O Settings dialog. For non-standard rates, the user can simply type in the value in the box.

The RS-422/485 ComProbe can monitor serial communications with 5, 6, 7 or 8 data bits and with 1, 1.5 or 2 stop bits. The device also supports all the standard parity types (None, Odd, Even, Mark, Space, and Ignore).

The user can also choose the bit order on their serial communication circuit. The choices are either LSB (least significant bit) first or MSB (most significant bit) first. LSB first is normal, while MSB first is considered "reversed" from normal. This option reverses the order of the bits within each byte.

The user can also choose to monitor either DTE only, DCE only or both DTE and DCE ends of the communication.
