QSTU1A
Note
For the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by
standard telephones (or any other device connected to a QSTU2 port), a QRCU3 must be
installed.
The QSTS2 PCB is factory-installed on the QSTU.
QSTU2 Configuration
The QSTU2 does not require configurations for the ring generator voltage level. Most standard
telephones and two-wire devices require 190; however, some devices may experience ring-trip at
190, and should be set at 130.
QSTU2 Installation
1. Make sure the power supply switch is Off.
2. Align the QSTU2 connectors J1, J2, J3, and J4 to the motherboard connectors J11, J12, J13,
and J14 respectively. Apply firm, even pressure to ensure proper mating of the connectors (see
