OTHER FUNCTIONS

NOTE:

• When using the PTTP terminal for packet operation, no

voice signals are transmitted from the microphone.

• When pushing [PTT] during data transmission, data

transmission is interrupted and the voice signal takes pri-
ority.

• Read the instructions supplied with your TNC carefully

before attempting packet operation with the IC-207H.

• Pin

DATA OUT is for 9600 bps operation only. This pin

cannot be used for 1200 bps operation.

9600 bps high speed packet operation

The IC-207H supports 2 modes of 9600 bps packet opera-
tion: G3RUH and GMSK.

Connect the IC-207H and a TNC as illustrated below.

G3RUH mode can handle 16 kinds of modulated wave
forms in order to maintain a communication link.

Set the TNC’s TX DELAY to 30–50.

Adjust the TNC frequency deviation if necessary (see page
at right).
