DATA TRANSFER MODE

There are three kinds of data transfer modes for the BCD output; “stream,” “auto print,” and “manual print.”

[Stream], [Auto Print], and [Manual Print]

The functions of these transfer modes are the same as described in {8-3 Standard Serial Output}.

TIMING

Strobe pulses are turned on approximately 7 ms after rewriting the output data and turned off in 17 ms.

If a hold input is turned on , an update of the output data will stop within 50 ms.

9-2 OP-03 RS-422/-485 INTERFACE

OP-03 provides external inputs/outputs to be connected to a personal computer. It can be set to RS-422 or RS-485. It

is different from the RS-232C in that up to 10 units can be connected in series (RS-422) or parallel (RS-485) by the

address capability. The data format, function settings, and so on are common to the OP-04 RS-232C.

Signal

System

Conforms to the EIA RS-422 or RS-485

Data bits 7 bits, 8 bits

Parity bits 1 bit (Even or Odd), None

Stop bits 1 bit, 2 bits

Baud rate 600, 1200, 2400, 4800, 9600, 19200 bps

Code used ASCII

ADDRESS CAPABILITY

The address capability responds only when your own

instrument is called from a host computer. The address

number of each instrument can be set from 1 to 99 with

RSF-09; 0 denotes no address capability.

When a command prefixed with an address “@xx”(xx is an

address number) is sent from the host computer, each AD-4401 compares this with address setting of the individual

instrument.

If a result of setpoint matches, the command will be analyzed and responded to. At this time, the instrument’s address is

added to the response.

Example of Adding the Address (For MZ Command)

SWITCHING TO RS-422/RS-485

Switching to RS-422/RS-485 is made with RSF-08. When more than two units are connected to the AD-4401, select "

Command " for RSF-02 and " With address " for RSF-09.
