Product description

 

Every  product is built to last for years with high- quality industrial grade materials.   is a RS-232 Mini Tester installed in series with any RS-232 interface in order to test the serial data link for any failures.

You can use it to troubleshoot faulty cables, bad connections or improper settings on computer/serial devices and more. The mini tester has nine double color (red and green) LEDs indicate the logic states for all 9 RS-232 data lines: DCD, RXD, TXD, DTR, GND, DSR, RTS, CTS and RI. Green for logic HIGH (True) and red for logic LOW (False).

Typical application scenarios:

  • Watching the TXD and RXD LEDs either changing states or flashing to know data transferring direction: from machine to computer or from computer to machine
  • Verifying TXD/RXD wires should be wired crossed(swap pin2 and 3) or straight through by observing TXD and RXD LEDs at a rest state
  • Verifying it is a DTE or DCE device (and whether you need a null modem or not.)  
  • Verifying whether modem controls are active, even if they're not being asserted
  • Testing control signal between control systems (AMX, Crestron, etc) and the devices they control
  • Determining if the serial connection is mated properly and if communications is occurring. Whether the wall control or the projector is malfunctioning
