COM2 Male DB9 Figure 12 Connecting COMM1 with PC For TLOOMX the opto isolated interface taps a 9V power from the host PC s serial port DIR signal pin hence it is necessary for the host PC to activate its DIR Data Terminal Ready pin pin 4 to logic 1 the programming software TRILOGI automatically tums ON DIR pin when it is running However for the users own communication routine to work propery this requirement must be met See BASC and C example programs Host485 bas and Host485 exe Connecting COMM 1 to Other RS232 Devices You may also connect COMM1 to another DCE device e g a modem on the condition that the other device is able to supply a 9V to pin 4 of the 10 T100MX PLCs Chapter 1 Installation TLOOMX PLC You will need to make a special cable which swap the transmit and receive signals as follow T100MD COMM1 Female DB9 Modem Female DB9 Figure 13 Connecting COMM1 to a MODEM Pin 4 and 6 are handshaking signals whose presence may be required by some modems to work propery so these pins are connected as shown in the diagram However some modems may not have sufficient drive Current on their DSR pin 6 to supply to the PLC s opto isolated interface If you find that the modem is not responding to commands from the PLC such as putting it to auto answer mode then you can use a separate 9V battery or extemal power supply to power up the Opto isolated RS232 circ
