Note – R5 – R8 on the board are optional. These resistors are used for ESD protection.
The device uses the DTR signal to determine when it is safe to transmit data to the TS driver. If
the system on which the TS driver resides does not have the DTR signal or does not use the DTR
signal, it is possible to connect the DTR signal on the device to ground. This will signal the
device that the system is always ready to receive data from it.
