EZSync RS232 Mini Tester with LED Indicators, DB9 Male to DB9 Female, EZSync911

Every EZSync product is built to last for years with high- quality industrial grade materials. EZSync911 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 malfuncti...
