・
The slave units may be connected with the master unit in two ways as shown below.
①
Connect the RS-232C connector of the computer with the connector J2 (D-sub 9-pin connector)
of the PW-A unit. (A cross cable may be used. However, it is necessary to set the RS-232C flow
control of the computer to "None" in such a case.)
②
Connect the RS-232C connector of the computer with IN of the connector J1 using the TA-60
(Our RS-232C-to-modular conversion cable).
・
As shown in Fig.21, a maximum of three PW-A or PWR power supply units may be connected
with the slave unit connected with the computer using modular cables. Any models may be
connected. In this application, the send messages must conform to the transmission and
reception procedures using the IF-41RS shown in section “9-4.” below.
Transmit message will be echo back to receiving side.
・
Set the address zero of the computer using the software.
・
For the RS-232C communication specifications, see Communication Specifications of IF41RS
in section 2.
※
Use the general-purpose cross or interlink RS-232C cables.
