RS-232 Check Tester Model: CT-100

Similar to the mini tester, except this tester gives a better understanding of the status of the data lines. Performs the same tests as MT-100, but in a more detailed manner.

RS-232 Mini Tester

Model: MT-100

Used to monitor the 7 most commonly used data lines to see if equipment has failed. Seven 2-color LEDs check status of TD, RD, RTS, CTS, DSR, CD and CTR.

Multi-link Tester & Breakout Box

Model: BB-25

Allows cable makers to configure custom cables. The BB-25 will visually let you know the status of lines 2, 3, 4, 5, 6, 8, 20, and 22 on the DTE side by utilizing red/green bi-color LEDs. Provides signal status at a glance (four states: mark, space, clocking, and off). Complete cable "breakout" and reconfiguration exists with 24 in-line switches and 54 in-line machine tool sockets. Includes handy carrying case, 10 jumper wires and a device wiring chart. Cable extends 4" from side of tester. Connectors: 1 male DB 25 and 1 female DB 25.
