HP 59306A Relay Actuator - instructions needed



#2

Hi,

I just received my relay control unit - HP 59306A Relay Actuator - but I need the instructions to operate it. Could someone help me?
I was wondering about using the 6 outputs to actuate as binary outputs, so, I could actually control 2^6 devices ... if it works, would be great!
I would appreciate any comments!
Best regards
Artur

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.

I have also checked that I can control the 59306A with my HP-41 with the HP82160A HP-IL module and the HP 82169A HP-IL/HP-IB Interface.

Assuming the example in my previous posting the command sequence would be as follows:

MANIO
6
SELECT
REMOTE
"A123"
OUTA
"B1"
OUTA
AUTOIO

The MANIO allows you to manually select the device you want to address. This is device number 6, which is selected with the SELECT command.

Then you switch the 59306A to remote mode so that it is controlled over the HP-IB (REMOTE command).

And finally you send the two command sequences with the OUTA commands.

At the end you can use the AUTOIO command to bring the HP 82160A to its initial (auto) state.

I'll try today at night.
I'm using the HP-IL -> HP-IB conversor to do the work. By the way, the conversor also have its own address. Shall I use it or just put it different from the Relay Actuator and disconsider it?
In translate mode is this address taken in account?

I hope my Christimas tree this year be more elegant, with my 41 controlling many colored lamps!

Thank you very much!

I take it this is the HP 82169A HP-IL/HP-IB Interface

In "translator mode" with control on the HP-IL side, the HP-IB addresses are used on the HP-IL side. So if your 59306A has address 6, then its HP-IL select code will also be 6.

Therefore, you should be carefull that none of the HP-IL devices should be assigned addresses that are in conflict with the addresses of the HP-IB equipment. So if you happen to have 6 devices on the HP-IL side, you should change the address of the 59306A to something higher up (e.g. 10).

Having said that, its also a good idea for the 82169A to have its own unique address.

Good luck

It works!
I'm very glad to see my HP-IL -> HP-IB is good and the beautifull LEDs and the strong relay noises!

Thank you very much, Vassilis! My Christmas will have a very nice tree with many lights!
