Table 3. HASCP communication interfaces
RS 232 (Standard)
DB9
a.
8 bit, No Parity, 115200 Baud (can go higher for short distances)
b.
Full Duplex (3 wire, shares return with 485)
c.
Minimal noise immunity
d.
Short distances (20 m)
e.
Single ended - unbalanced
RS-485 (Standard)
Terminal block
a.
8 bit, No parity, up to 921600 Baud
b.
Half Duplex (3 wire, shares return with 232)
c.
Good noise immunity
d.
Long distances (1000 m)
e.
Differential – Balanced – one line true signal and other line is
false signal or inverted signal. The receiver detects the input and
sees which signal is more positive than other.
Power
9V – 24V
TRIG Out
Trigger output line from HASCP unit
CHGND
Chassis Ground line (used in case of EMI issues)
TRIG IN
Not available and is intended for future use
