8.2 Communication software APT-COM™ 3 DataControlSystem (BD, option ED)
The oven is regularly equipped with a serial interface RS 422 that can connect the BINDER
communication software APT-COM™ 3 DataControlSystem. The connection to a computer is established
using the unit interface via an interface converter RS 422 / RS 232.
The actual temperature values are given at adjustable intervals. Programming can be performed
graphically via PC. Up to 30 chambers with RS 422 interface can be cross linked. For further information,
refer to the operating manual of the BINDER communication software APT-COM™.
Pin allocation of the RS 422 interface:
pin 2: RxD (+)
pin 3: TxD (+)
pin 4: RxD (-)
pin 5: TxD (-)
pin 7: Ground
If several incubators BD or heating ovens ED (option) are to be recorded via a PC, each one
must be allocated a unique address. Addressing is performed via the R3 controller (see
chap. 6.4.3 ).
8.3 Analog output for temperature (option)
With this option the chamber is equipped with an analog output 4-20 mA for temperature. This output
permits transmitting data to external data registration systems or devices.
The connection is carried out as a DIN socket at the rear of the chamber as follows:
ANALOG OUTPUT 4-20 mA DC
PIN 1: Temperature –
PIN 2: Temperature +
Temperature range:
BD: 0 °C / 32 °F to +100 °C / 212 °F
ED, FD: 0 °C / 32 °F to +300 °C / 572 °F
A suitable DIN plug is enclosed.

8.4 Additional Pt100 temperature sensor (option BD)
An additional fixed or flexible temperature sensor Pt100 permits measuring the chamber temperature
(fixed Pt100) or the temperature of the charging material (flexible Pt100) by means of an independent
measuring system with Pt100 entry. The sensor top protective tube of the flexible Pt100 can be immersed
into liquid substances.
Technical data of thePt100 sensor:
• Three-wire technique
• Class B (DIN EN 60751)
• Temperature range up to 320 °C / 608 °F
• Stainless steel protective tube 45 mm length
material no. 1.4501
