This type of port provides

- Output for infra-red emitters (IR Adapter), maximum IR output rate is 1.2 MHz.
- RS-232 serial output (one-way), the maximum serial data rate is 115 200 Bd (bps), and output signal levels for RS-232 are in the -12 V to +12 V range.

The IR outputs and RS-232 outputs can be combined on independent ports (for example three ports can be used as IR, and five ports can be used as RS-232).

# IR Output port

This mode provides output for infra-red emitters IR Adapter. Parameters of IR output are as follows:

- The maximum IR output rate is 1.2 MHz.
- Up to three original infra-red emitters IR Adapter can be connected to each output in parallel. All emitters send the same IR codes. This configuration can be used for different types of devices.
- Up to ten IR Sprayers with external power supply can be connected to each output in parallel.

> ⚠️ It is not recommended to connect more infra-red emitters of various manufacturers in parallel because the output can be either overloaded or damaged.

# Serial Output

## Overview

This mode provides a one-way RS-232 output channel. That means the device is controlled without the possibility to read any feedback.

The **parameters **of serial output are as follows:

- The maximum serial data rate 115 200 Bd (bps)
- The output signal level range is -12 V to +12 V.

> ⚠️ In case there are more ports in the unit, all pins labelled G are connected.
