34398A
Digital Cable
The Keysight 34398A is an RS-232 cable, 9 pin (f) to 9 pin (f). Standard RS-232 cables are easy to find, but making them work is a different story. The Keysight 34398A has been verified for compatibility with Keysight's bench instruments to take the mystery out of RS-232 pinouts. The Keysight 34398A includes a 9-pin (f) to 9-pin (f) RS-232 cable and a 9-pin (m) to 25-pin (f) adapter.

ADLINK's NuDAM data acquisition modules make up a total acquisition network and control system. Up to 256 NuDAM modules an be romotely controlled on any RS-485 network from a host computer, via a single serial RS-232, allowing communication from as far as 4000 feet from the host. Based on the RS-485 multi-drop network system, each module has a unique address ID, whereby simple ASCII command & response protocols through the standard RS-485 interface can control all the NuDAM modules in the RS-485 network. The NuDAM modules provide direct communications with a wide variety of sensors, perform all signal conditioning, scaling, linearization and conversion, and can acquire measurements of temperature, pressure, flow, voltage, current, and multiple digital signal types.

Four And Two-Port Multi-Protocol RS-232/422/485 M.2 Cards
M.2-COM-4SM Family
-
The M.2-COM-4SM family of cards feature high performance 16C950-class UARTs. Available in 4-port and 2-port versions, each port is capable of communication speeds up to 921.6kbps in RS-232 (differential modes support speeds as high as 3Mbps) and has 128-byte deep transmit and receive FIFOs. Large FIFOs protect against data loss in multitasking operating systems, reduce CPU utilization, and improve data throughput, while reducing or eliminating inter-character or inter-packet pauses. The advanced integrated circuit with pre-scalar supports a wide variety of custom baud rates, and any rates not otherwise achievable can be supported via a custom factory-installed crystal oscillator (up to 10Mbps!).
