What are you using for a cable? The port on the 90-30 power supply is RS-485. Most people use a a converter to go from RS-485 to RS-232, although RussB and others have posted the pinouts for this "cheater" cable that works without any converter.


9 pin 15 pin-M

Rd 2 --------------- 12 SD+(B)

Td 3 --------------- 10 RD+(B')

Sig.Gnd. 5 ---------------- 7 SG

RTS 7 ---| |--- 6 RTS+(B)
| |
CTS 8 ---| |--- 15 CTS+(B')

DTR 4 ---| |--- 8 CTS-(A')

DSR 6 ---| |--- 14 RTS-(A)
