1. RS-232C bi-directional interface functions
All functions can be duplicated remotely by using the RS-232C
interface. Commands must be sent in uppercase ASCII charac-
ter format followed by a carriage return [CR].
RS-232C Signal: 8 data, 1 stop, no parity. Baud Rate: 19200 bps
RS-232C INTERFACE FUNCTIONS (Upper case ASCII format)
COMMAND FUNCTION RESPONSE*
T[CR] Select real time mode R[CR]
P[CR] Select peak mode R[CR]
If OR peak is programmed
P[CR] = peak
If AND peak is programmed
P[CR] (1st time)= +peak
P[CR] (2nd time)= – peak
Z[CR] Tare Display R[CR]
D[CR] Transmit display data [direction][value][units][mode]
[go/nogo/overload][CR]
[direction] +=CW
–=CCW
[value] 4 digits w/decimal
[units] K, N, or O
[mode] T=real time value
P=peak value
H=Hold value
M=Memory value
[go/nogo] H=+NG
O=OK
L=-NG
E=Overload
V[CR] Transmit Peak data P+[value][units][CR]
P– [value][units][CR]
g[CR] Continuous data output (10 data/sec)
Y[CR] Stop continuous data output
K[CR] Select “kgf-cm” units R[CR]
N[CR] Select “N-cm” units R[CR]
O[CR] Select “lbf-in” units R[CR]
B[CR] Delete last data stored in memory R[CR]
M[CR] Store data R[CR]
I[CR] Recall memory data Data format is the same as D
command response. It will out-
put END[CR] at the end of data
C[CR] Clear memory R[CR]
EXXXXYYYY Set high/low setpoints(4 digit) R[CR]
[CR] XXXX=High, YYYY=Low
E[CR] Read high/low EXXXXYYYY[CR]
setpoint values (4 digit)
XXXX=High, YYYY=Low
