9.3.3 Switch on/off Interface
An input signal is available to switch on/off the TRM-300.
If the pins 10 and/or 11, which are internally connected, are left in open-circuit then the TRM-300 will be
switched off. If they are connected to ground, then the TRM-300 will be switched on.
For the data and control interfaces, shielded interconnecting cables are required in order to minimize the
possibility of RF interference.
PowerTrunk recommends its RS232, I/O & Switch Cable accessory and its USB, I/O & Switch Cable
accessory.
