“$A5,0,0,3, ‘Y11’” turns Closure 1 on
“$A5,0,0,3, ‘Y20’” turns Closure 2 off
“$A5,0,0,3, ‘Y21’” turns Closure 2 on
Device Status
SP
"$A5,0,0,2,'SP'" (6 bytes)
2-way systems only
Queries the Head-End for the number of devices present on the network and the number of devices
expected.
Response
Description
Key-I/O
K
“ ‘<’,0,0,2,'K',<IR Key>" (6 bytes)
Sent when the Reset or Emergency buttons are pressed, or when I/O 1 or 2 receives a closure. PC
software or a control system connected to the Control RS-232 port can receive the response and
activate a programmed event.
101 = Reset button pressed
229 = Reset button released
102 = Emergency button pressed
230 = Emergency button released
103 = I/O 1 input closed
231 = I/O 1 input opened
104 = I/O 2 input closed
232 = I/O 2 input opened
Device Query
SP
" '<',0,0,4,'SP',<number devices present>,<number devices expected> (8 bytes)
Sent in response to HE Device Status query.
Tip
: If the number of present and expected devices match, the green Net LED on the HE will blink
once per second. If the two numbers do not agree, the LED blinks twice per second.
