[mh] Weeder to close contact?

Hello,

  I have a weeder WTDIO-M which does a pretty good job of notifying me when a switch closes. I’d also like to use it to trigger a NO switch. Looking at the document, I _think_ I can do this by setting it to a high state:

HIGH, H chn time, Make channel chn an output and set high for time x10 microseconds. chn = A-N, time = 1 to 65535. If time omitted, chn remains high.(Note 3)

However looking at the MH code, I’m not sure the serial configuration. This is my button:

$button = new Serial_Item( 'AAH', OFF, 'weeder' );
$button->add( 'AAL', ON,     'weeder' );
$button->add( 'A!',  'reset', 'weeder' );
$button->add( 'ASA', 'init',  'weeder' );

So close a contact I need to send an H and microseconds, 

$contact = new Serial_Item( 'ABH50000', ON, 'weeder' );

So set $contact ON should send a high level with a half second duration. I think this will close the contact, however that will leave the $contact in an ON state, is this correct?

Anyone use a weeder board to close contacts?
