TX Keying lines

Looking for information on the TX keying lines with the Flex-6300, I see from manual RCA jack can sink 140 ma, I don't see specs for line on 9 pin connector. I need to key my Elecraft KPA500 and switch two additional ( perhaps 3) devices. One device is the DX Engineering RTR-1A, the other is MFJ 1026 and perhaps the 20 VDC power supply used with Pixel Loop. Really love the folks around me with Plasma TV's

From what I can gather, the 6300 only has one key line. If you need several, you may be able to isolate each one with a schottky diode (if what is keyed can handle the drop across them).
If the keyed devices won't key that way, you might be way ahead to key a couple of optoisolators with SSR outputs. An ASSR-1228 would do nicely. These have two 'switches' each and will switch near 60v at 200ma. Maybe a bit more if that are all DC.
