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

[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

*Note: E[CR] response if the command is not accepted.
