14.2 Interface RS 422 (option)
With this option, the chamber is equipped with a serial interface RS 422 instead of the Ethernet Interface,
to which the BINDER communication software APT-COM™ 3 DataControlSystem can be connected. In
adjustable intervals, the actual temperature and humidity values are put out.
Pin allocation of the RS 422 interface: Pin 2: RxD (+)
Pin 3: TxD (+)
Pin 4: RxD (-)
Pin 5: TxD (-)
Pin 7: Ground
14.3 Analog outputs for temperature (option)
With this option, the chamber is equipped with analogue outputs 4-20 mA for actual value and set-point
value of temperature. These outputs permit transmitting data to external data registration systems or de-
vices.
The connection is carried out as a DIN socket (10) in the lateral control panel as following:
ANALOG OUTPUTS TEMPERATURE 4-20 mA DC
PIN 1: Temperature actual value –
PIN 2: Temperature actual value +
PIN 4: Temperature set-point value –
PIN 5: Temperature set-point value +
Temperature range: -40°C / -40°F up to +180°C / -356°F
A suitable DIN plug is enclosed.
