6.3.3 INSTALLATION OF RS232 CARD
The RS232 Interface (ISO_RS232_CONV-1103 Card) card may come already
installed, if ordered. If this interface is to be installed later, the card can be mounted
on the rear panel of the unit using L-clamp provided on the card itself & following
cards &cables shall be provided along.
Cards:
♦ ISO_RS232_CONV-1103
♦ VSP-FP-DAC-1003
Cables:
♦ 3 PIN serial communication (Tx, Rx) data cable (J10) on ISO_RS232_CONV-1103
♦ +10V supply cable to be connected on 3 PIN connector (J3) on ISO_RS232_CONV-1103
Following is the procedure to install the card. :
♦ Release the TOP COVER of the unit by unscrewing 6 screws at the top & 6 screws at
the side panel of the unit.
♦ Remove the TOP COVER (upper plate) of the unit by sliding it out.
♦ You will see a number of cards inside the unit. Please do not touch any of these.
♦ Remove the existing communication card / Connector, which is connected to the slot at
the back of the unit marked as ‘DIGITAL INTF’.
♦ Fit the card “ISO_RS232_CONV-1103” on the rear panel of the unit using L-clamp pro-
vided on the card itself.
♦ Check if the link at JP1 is open
♦ Initially disconnect the 26-pin cable from J4 on “VSP-DPM CONT1003” card.
♦ Insert the card “VSP-FP-DAC-1003” onto the “VSP-DPM CONT-1003” such that 16-pin
DIL female (J3) & 26-pin DIL female (J1) on “VSP-FP-DAC-1003” are plugged in 16-pin
DIL male (J7) & 26-pin DIL male (J4) on the “VSP-DPM CONT-1003” card respectively.
♦ Now connect the 26-pin flat cable, which was removed from J4 on “VSP-DPM CONT-
1003” to the 26-pin DIL male (J2) on “VSP-FP-DAC-1003” card. So now the 26-pin DIL
male (J1) on “VSP-POT-IMON-0703 “is connected to 26-pin DIL male (J2) on “VSP-FP-
DAC-1003” card.
♦ Do not change the connection between 26-pin DIL male (J2) on “VSP- POT-IMON-0703 “
& 26-pin DIL male (J6) of “VSPDDC-1.2KW-1003D”
♦ Connect 3-pin SIL connector (J3) on “VSP-POT-IMON-0703“ to the 3-pin SIL connector
(J2) on “ISO_RS232_CONV-1103” card, which is connected to the switch on rear panel,
which decides to select either remote or RS 232 interface.
♦ Two connectors are connected to 4-pin SIL connector (J2) on the “VSPDDC-1.2KW-
1003D” one of which is 4-pin SIL connector (J4) on “VSP-POT-IMON-0703“ & other is 3-
pin SIL connector (J3) on “ISO_RS232_CONV-1103” card
♦ Using 3-pin SIL connector connect J10 of on the “ISO_RS232_CONV-1103” card with J10
on “VSP-DPM CONT-1003” card, which are the Transmit & receive signals along with
common ground signal.
♦ Verify the signal connections again & select RS232 Interface using slide switch provided
on rear panel.
♦ Turn on the unit & test its functionality. Replace the TOP COVER and close the instru-
ment.
