Frequently Asked Questions (FAQ)
- Q1: Does T8123 support hot swapping?
A: No. Always power down the chassis before installing or removing this adapter. - Q2: Can I use both MODBUS master and IRIG-B at the same time?
A: Yes. MODBUS master is a software option and does not affect IRIG-B hardware connections. - Q3: What happens if the PSU shuts down?
A: The PSU monitor connection sends a signal to the adapter, which then reports it via the fault outputs. - Q4: How do I know if the adapter is working?
A: Check the diagnostic port with Trusted engineering software. Also look at onboard LEDs. - Q5: Is the 12-month warranty extendable?
A: Yes. Contact us for extended warranty plans and on-site support options.
Buyer Guidance & Experience Tips
- Order IRIG-B option if you need precise time sync across multiple chassis.
- Enable MODBUS master only when polling many slave devices.
- Keep spare T8123 in stock for critical TMR systems.
- Use FedEx Priority for urgent replacement. Use DHL Economy for lower cost.
- Always verify RS422/485 wiring before powering on to avoid damage.
- Label your fault/fail connections for easier troubleshooting later.
