3.3 Cable Length

The cable lengths given below are contingent to error-free data transmission.

TTY interface

• CP 523 active TTY : maximum cable length 10 m/33 ft.

• Peripheral device active TTY : Refer to the User's Guide for the relevant device for the

permissible cable length (maximum 1000 m/3280 ft).

Note:

Voltage drops on the cable and the module's sending and receiving elements must be noted

when using longer cables ( 2.2).

RS-232-C (V.24) interface

Cable length is not critical up to 15 m/49 ft. In general, longer cables can be used in conjuction

with lower baud rates.
