Section 2 Installation & Setup
2.4.5
Platinum Z FM and IBOC Transmitters
Since the only difference between the Platinum Z FM analog and the Platinum Z IBOC
transmitter is the exciter (at least as far as the eCDi™ installation is concerned) these
transmitters will be discussed as one.
2.4.5.1
Mounting and AC Power
The eCDi™ unit can only be mounted in the transmitter if it has a single exciter. This
would also require bringing an external source of 110/220Vac into the transmitter.
IMPORTANT:
Do not plug the eCDi™ into the spare ac cord that is already wired in all Z FM
Transmitters for the second exciter. This cord is 220/240Vac, which is okay, but is
switched with the transmitter on/off switch, which is unacceptable.
2.4.5.2
Transmitter Serial Connection
Connect the provided 9 pin to 25 pin null modem adaptor to J21 on the Display/
Backplane Board in the transmitter control unit. J21 is on the left side of the Display/
Backplane board right next to the Master Controller, see Figure 2-13 for location of the
connector.
Connect one end of the provided 10ft or 50ft serial cable labeled “XMTR” (either cable
can be used depending on where the eCDi™ is mounted) to the serial port on the
eCDi™ labeled “XMTR”. Connect the other end to the 9 pin to 25 pin null modem
adaptor previously connected to J21 on the Display/Backplane Board. See Table 2-2 for
DB9 (DTE) to DB25 (DCE) conversion pinouts.
