SRC-8 III Installation and Operation Manual
INSTALLATION
Command Additional Data Bytes Function
47h Disable error & good responses
48h n Latch output n (00 – 07)
49h n Unlatch output n (00 – 07)
4Ah n t Pulse output n (00 – 07), t= time
(1-63h =.1-9.9sec)
4Bh n Poll output n (00 – 07) (see 55h)
4Ch n Poll input n (00 – 07) (see 55h)
4Dh All Output status request (see 52h)
4Eh All Input status request (see 53h)
4Fh Unit version request (see 54h)
Output Response from SRC-8 III Function
50h Error response if enabled by 46h
51h Good response if enabled by 46h
52h n Response of 4Dh, outputs are sent as 1 byte
53h n Response of 4Eh, inputs are sent as 1 byte
Also sent when any input changes state
54hnn Response to 4Fh outputs version,(ie 01h,
03h=ver 1.03)
55h n Response to 4Bh or 4Ch for polled output
or input where the three highest bits of n
are used to identify if an input/output is
low/high and the lowest 5 bits
identify the input or output. n = 00h –
07h if input n is low, n = 20h – 27h if
input n is high, n = 40h – 47h if output n
is low and n = 60 – 67 if output n is high.
n=cccnnnnn where ccc = 000 = input low,
001 = input hi, 010 = output lo, 011 =
output hi. nnnnn lowest 5 bits used to
identify the input or output
Example of binary exchange:
To poll the status of outputs of unit 2 when outputs (0-7) 0, 6 are high, all else low:
