#109838 - Forget about resistance etc think ULs on Responding to: ???'s previous message |
Straigh forward question is that how many AT89c2051 can be attached with the RS485.
NONE, you can attcah 32 Unit loads (UL) to a RS485 transciever. Mean to say unit load is not clear to me.may someone explain it. Forget about resistance etc think ULs only. ANY RS485 driver can drive 2 terminators and 32 ULs. Thus if you use devices which are specified as 1/2 UL then, of course, you can connect 64 devices etc. Erik |
