2.4.1.2 Optional –48VDC Prime Power Connector (J1)
Prime power is supplied to the converter unit (and for SSPAs of
≤ 8 Watts) through a
4-pin circular male connector (J1). For the converter unit, the prime power input
requirement is -36 to -48 VDC, 200 watts.
2.4.1.3 Remote Connector (J2)
The Remote Connector (J2) is a 26-pin, circular, female connector (P/N: PT06E16-
26P(SR) ). It is used to allow remote control and monitoring of KST-2000A/B operating
parameters. Interface is via EIA-232, EIA-485, or EIA-422 half-duplex. Refer to Table
2-3 for pin assignments.
Note: The user must assemble this cable. Figure 2-3 shows the connections for an
EIA-232 adapter for use with a PC COM port.
