Connection of RS-232C
The TLD100 can send and receive commands and status information via RS-232C to external devices. The external
device is connected with a 3 wire cable. The cable should be cross-connected. In other words, the transmitting signal
(TxD) of this unit is connected to the receiving signal (RxD) of the external device, and the receiving signal (RxD) of this unit
is connected to the transmitting signal (TxD) of the external device. The ground signal of each device should be connected
to one another.
*
Cables to be connected should be selected depending on the external devices to be
connected. The above illustratesthat the external device has a D-sub 9-pin connector.
