5-8-1. RS-232 Configuration
The GRS-6052A/6032A contains a DB 9-pin, male RS-232 connector for serial
communication with a computer or terminal. The GRS-6052A/6032A RS-232
interface is configured as an RS-232 “Data Terminal Equipment” so that data is sent
from pin 3 and received on pin 2. For remote controls, the RS-232 interface has to be
connected with a computer or terminal.

When the GRS-6052A/6032A is set up with a RS232 interface, please check the
following points:
z Do not connect the output line of one DTE device to the output line of the other.
z Many devices require a constant high signal on one or more input pins.
z Ensure that the signal ground of the equipment is connected to the signal
ground of the external device.
z Ensure that the chassis ground of the equipment is connected to the chassis
ground of the external device.
z Do not use more than 15m of cable to connect devices to a PC.
z Ensure the same configurations are used on the device as the one used on PC
terminal.
z Ensure the connector for the both side of cable and the internal connected line
are met the demand of the instrument.
