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.
Communication conditions
The communication configuration of external devices to be connected should fulfill the conditions in the table below.

Connection of microphones CH1 and CH2 and MIX OUT connector
This unit employs BALANCED output terminals. These terminals should be connected to an external device equipped with
balanced input connector. If these terminals are connected to an external device with unbalanced input connector, select
a cable as described below.
* Cable with optimal plug type should be selected depending on the device to be connected.
