2.5.5 Prime Power (J5)
The AC power is supplied to the RFT by a 3-pin power connector. Normal input voltage
is 90 to 232 VAC, 47 to 63 Hz. The AC pinout is as follows:
Pin # Name Function Wire Color
A HI Line Brown
B LO Neutral Blue
C GND Ground Green/yellow
Maximum power consumption is 800W for the RFT-1225.
A circular 4-pin power connector is used for the DC (48 VDC) option. The pinout is as
follows:
Pin # Name
A + INPUT
B GROUND
C - INPUT
D NC
2.5.6 Serial Remote Control (J6)
The remote connector on the RFT is used to interface the M&C functions to a remote
location. This interface can be either EIA-232-C or EIA-485.
When using an EIA-485 interface, the transmit and receive signals are able to
accommodate either type of remote equipment pinouts. As long as the polarities of the
remote equipment TX and RX signals are correct, this remote interface will be
completely compatible.
Refer to Table 2-2 for a list of pinouts for the J6 connector.
For standard EIA-232-C or EIA-485 applications, an adapter cable must be used to
connect the 26-pin connector (J6) to a standard 9-pin D.
Refer to Figure 2-1 for an illustration of the adapter cable with its pinouts.
