Re: HP 59306A Relay Actuator - instructions needed Message #2 Posted by Vassilis Prevelakis on 15 June 2005, 1:03 a.m., in response to message #1 by Artur - Brasil
If you look at the device's underside you will see the instructions.
Basically the DIP switch on the back sets the address of the machine on the HP-IB bus. SO lets say you configure it as follows:
+----------------------+
| A5 A4 A3 A2 A1 |
+----------------------+
| X X X X X |
| X X |
+----------------------+
Giving it an HPIB address of 6.
Then you send an ASCII string to the machine telling it what you want it to do:
I.e. if you send it "A123" it means that you want it to turn "on" relays 1, 2, and 3. By "turn on" I mean light the indicator lamp and connect terminal A to terminal C on the back of the machine.
The above command would therefore connect 1A to 1C, 2A to 2C, and 3A to 3C.
If you now want to "turn off" relay 1, you would send the string "B1" to the machine. The 59306A will then turn off the indicator light under button 1, and switch relay 1 so that 1B is linked to 1C.
Now, how do you send the string to the 59306A? Well it depends on what king of controller you have.
If, for example, you have an HP-85 with the I/O ROM, you'd just say:
OUTPUT 706;"A123"
and then
OUTPUT 706;"B1"
-------------------------------
As to whether you want to use the 59306A to control 2^6 devices, I think it is possible, but this baby is LOUD!
When the relays switch, the make a hell of a racket. You do not want your 59306A switching a lot, it'll sound like a machine gun.
