Figure 15- Rs232 Connection With Matrix-Y-1 Cable; Figure 16- Matrix-Y-1 Wiring Schematic - Network Technologies ST-nXm-U Installation And Operation Manual

NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH
Note: The RS232 connection on the switch may only have a single 9 pin "RS232" female connector. In this case, in
order to connect multiple NODEMUX units together, a Matrix-Y-1 cable must be used. (see Figure 15). No loop back
plug will be used with this configuration. See Figure 16 for the pinout of the Matrix-Y-1 cable.
