1 Introduction
This document describes the features of the peitel handset HA57 EVO. The hardware as well as the available terminal
protocols HA20x and HA400 for the communication with the handset will be described in detail in this document.
The essential difference between the HA400 and HA20x protocol is the signalling of key events.
Figure 1: HA57 EVO
The adjacent figure is showing the upper side and bottom side of the handset HA57 EVO.
The handset consists of the following main components:
Microphone & Earpiece
Key panel with 20 keys
Graphic 2.4'' colour LCD with background lighting
Spiral cable with 10-pin Western connector
PTT button (Push to Talk)
To connect the handset to a target system a 10-pin Western system connector is used. Besides the audio signals, a
RS232 interface is available at the connector for communication with the target system.
In the remainder of this document, the controlling system is referred to as the "Host" or "Host system" and handset
as the "Client". To enable communication between the Host and the Client the so-called "Terminal Interface" has
been defined. The Terminal Interface consists of the "RS232 Interface" (hardware, see 2.4 Communication Settings)
and the "Terminal Protocols" (software, see 3 Firmware (Terminal Protocols) ff). These protocols are based on the
Terminal Protocols HA20x and HA400 used in the handset HA87, HA88 and HA57 SDK for a downwards compatibility of
the handsets. Additional commands have been defined to address the enhanced features of the handset HA57 EVO.
The selection of the Terminal Protocol to be used can be done via the Setup Menu as described in section 4.4
Emulation.
The handset works as

Output device (transmitter)
When recognizing a pressed key, a respective key code from the chosen protocol is sent to the host system.
This can initiate respective actions.
Input device (receiver)
The handset is controlled with control sequences by the host system. In this way, for example, a text can be
displayed on the handsets display.
The following figure illustrates the application principle:

The HA57 EVO offers the possibility to integrate user applications. See also chapter 5 Own Software.
