Serial Ports -> [Rear|Front] Settings 4.1 Serial Port Operation 4.1.1 Overview The RFI-148/900250 has two RS-232 serial ports, providing support as shown in Table 1. The serial port pin-outs can be found in Appendix A.3 on page 45. Serial Ports...
4.3 Transmitter Operation Radio -> Power 4.3.1 Transmit Power The RFI-148/900250 supports transmit power from 20 to 250 Watts in 1 Watt increments. POWER FOLDBACK The power foldback is a configurable percentage which calculates the power to foldback to when the scale transmit power fault action is latched.
Software PTT is available using Hayes AT commands, through the Cruise Control GUI, or through the terminal menu interface. It is also selected implicitly when enabling TNPP or PET/TAP on either a serial or Ethernet stream. RFI-148 & RFI-900 High Output Power Paging Transmitters User Manual Page 23 of 99...

(Secondary) Figure 18: Hot standby system The RFI-PHSB contains a high power RF switch to ensure minimal signal loss from the active RFI-148 250 to the antenna. The pair of RFI-148 250 transmitters assume either a Primary or Secondary role. The role of the transmitter is determined by which port it is connected to the RFI-PHSB, there are two ports “Primary”...
7.3 Operation The Primary RFI-148 250 has control of the RF switch position. The default switch position, when no Primary unit exists or the RFI-PHSB is unpowered, is for the Secondary unit. Upon power up the Primary unit will always favour itself for the RF switch position, but the power up default is to leave the switch in the Secondary unit position.

G.2.4.2 High Reverse Power or Reverse Power Foldback A high reverse power fault indicates a hardware failure of the circulator inside the paging transmitter. Failure of the circulator can cause RF spectrum splatter, so transmit is disabled. Return the unit to STI Engineering for repair.
There are no faults active. A unit configured to transmit at a high power level needs similarly higher sensor cutoffs, see appendix G.1. Otherwise, low transmit power could indicate a hardware failure. If troubleshooting fails, return the unit to STI Engineering for repair.
