1. Introduction

This document describes the command protocol that is used to communicate with the Vortex EF2211

via its RS-232 port.

2. RS-232 Hardware

The communication between the Vortex and a host controller is conducted via the RS-232 port on the

back panel of the Vortex. The Vortex's RS-232 port operates at the following settings:

●

Bit Rate (bps): 9600 (default), 19200, or 38400

●

Data Format: 8 data bits, no parity, 1 stop bit (8N1)

●

Flow Control: none (default) or hardware (RTS, CTS)

Note that although the flow control setting is user selectable to none or hardware, hardware flow

control must be used when updating the firmware of the Vortex. This means that while a 3-wire RS-

232 cable (RX, TX, GND) is acceptable for control of the Vortex, the minimum cable for updating

firmware should contain 5 wires (RX, TX, RTS, CTS, GND).

3. Programming Tips

3.1. Initialization

During power up of the Vortex device or initialization of the host program, electrical fluctuations on

the RS-232 lines may cause the Vortex to receive spurious data. After initialization, the host program

should send a few carriage return characters (^M, ASCII 13) to the connected Vortex to flush out any

spurious characters it may have received. Failure to do this could result in the Vortex ignoring the first

command received after initialization.

As part of the host program initialization, the host will want to synchronize the status of its controls

with the current status of the Vortex devices that are being controlled. The host could initialize its

controls to default values and then send commands to the Vortexes to set them to the same state.

This approach has significant disadvantages since initializing the host program could undo settings

made by other host programs or by the front panel controls of one of the linked Vortex devices. A

better approach is to query the linked Vortex devices for their status and set the host program

controls based on the return values.
