SRC-16 Plus Installation and Operation Manual
SETUP
Binary Hex Commands
Binary hex mode is offered as alternative serial command set. To enable, turn SW1-5
on. All commands start with a 2Ah (ASCII *)
The first byte contains the board ID and the byte count iiibbbbb
The byte count is the number of bytes after the byte containing the byte count
including checksum. The second byte contains an 8 bit command. Some commands
are followed by data bytes. Checksum is the LSByte of the sum of all bytes preced-
ing checksum including start character. Binary hex commands must be received as
a packet. If 50ms or more passes after a character is received, with no new charac-
ter following, the SRC-16 Plus will begin looking for a new string.
Command Data Bytes Example Function
41h 2A 02 41 6D Set serial speed to 4,800
42h 2A 02 42 6E Set serial speed to 2,400
43h 2A 02 43 6F Set serial speed to 9,600
44h 2A 02 44 70 Set serial speed to 19,200
45h 2A 02 45 71 Set serial speed to 38,400
46h 2A 02 46 72 Enable error & good responses
47h 2A 02 47 73 Disable error & good responses
48h n 2A 03 48 01 76 Latch output n (00 – 0F
49h n 2A 03 49 01 77 Unlatch output n (00 – 0F)
4Bh n 2A 03 4B 01 79 Poll output n (00 – 0F) (see 55h)
4Ch n 2A 03 4C 01 7A Poll input n (00 – 0F) (see 55h)
4Dh 2A 02 4D 79 All Output status request (see 52h)
4Eh 2A 02 4E 7A All Input status request (see 53h)

Response from SRC-16
Command Data
Bytes Function
50h Error response if enabled by 46h
51h Good response if enabled by 46h
52h nn Response of 4Dh, outputs are sent as 2 bytes
53h nn Response of 4Eh, inputs are sent as 2 bytes, also sent
when any input changes state.
54h nn Response to 4Fh, outputs version number.
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 4 bits iden-
tify the input or output. n = 00h – 0Fh if input n is
low, n = 20h – 2Fh if input n is high, n = 40h – 4Fh if
output n is low and n = 60 – 6F if output n is high.
n=cccxnnnn 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
To poll the status of outputs of unit 2 when outputs (0-
F) 0, 6 are high, all else low:
