1Introduction

1.1 Description

The SSR-1 is a flexible and robust serial data recording device that takes care of the details of

storing data so that you can focus on your application. Up to three streams of serial data can be

recorded simultaneously, and each channel is configurable with a variety of serial and storage

options. Streams can be recorded automatically at power up, on command through a digital or

PWM input, or using software commands.

1.2 Features

Simultaneously records three asynchronous serial channels

Two RS-232 channels and one 5V TTL compatible channel

(Version available with 3.3V CMOS channels instead of RS-232. Contact us for details.)

Up to 230.4k baud recording on all channels

(A high-speed version is available supporting 921.6k baud recording on all channels)

Wide supply voltage (4.5 to 32VDC)

Small size: 1.65 x 1.23 x 0.45 inches (42 x 32 x 12 mm)

Supports MicroSD and MicroSDHC cards

FAT12, FAT16, and FAT32 file system support

Long File Name support

Support for raw and time-tagged recording

Battery backed real time clock powered by an onboard button cell battery

Flexible record control: digital input, PWM input, software controlled, or automatic

User shell for configuration and file system operations

Binary control protocol for machine automation

Flexible recording modes (overwrite/append, user defined path and file names, etc.)

WARNING: Improper removal of the backup battery can damage the SSR-1. To

remove the battery, use a blunt stick to push the battery out of the holder.

DO NOT PRY OR PULL THE BATTERY.

CAUTION: Like most electronic components, the SSR-1 can be damaged by

electrostatic discharge. Observe typical precautions for handling electrostatic

discharge sensitive devices.

2.3 Part Numbers

SSR-1 part numbers follow the following form:

SR1__T_

The standard configuration is SR122T.

H –high-speed variant support 921.6k baud recording

22 –channels 1 and 2 are RS-232

CC –channels 1 and 2 are 3.3V CMOS (not 5V tolerant)

(Unless otherwise noted, all specifications and notes in this document apply

to the 22 version. Contact us for questions on the CC version.)

2.4 Connecting the SSR-1

The pins of the main connector are shown in Figure 3 and described in Table 1. The default

configuration of the SSR-1 provides access to the user shell (see Section 4 Interactive Shell, for

details) on channel 1 and causes channels 2 and 3 to record when the digital input command pin

(DI, pin 15) is pulled to ground. All channels default to 115200 baud, 8 data bits, no parity, and

1 stop bit.

WARNING: Channels 1 and 2 are RS-232 voltage level compatible, and channel 3

is 5 Volt tolerant, TTL compatible, 3.3V CMOS. Do not connect an RS-232 device

to channel 3 of the SSR-1.

Wiring for a typical application is shown in Figure 4. The default SSR-1 configuration is

assumed. In the figure, channel 1 is connected to a standard PC serial port for shell access,

allowing configuration and file system operations via a terminal application on the PC. Channel

2 records data from an RS-232 device and channel 3 records data from a TTL compatible device

when the Close to Record switch is closed.

2.5 Using the SSR-1

The SSR-1 is shipped in default configuration, which sets all channels to 115200 baud, 8 data

bits, no parity, and 1 stop bit. Channels 2 and 3 are configured to record when DI is pulled low.

Channel 1 is configured to present the user shell.

On power up, the SSR-1 displays a boot loader announcement and device details. If a channel is

attached to the user shell, it will present the user shell prompt. A typical power-on sequence

would produce output similar to:

Details of the shell interface are provided in Section 4 Interactive Shell. As an example of shell

usage, consider changing the command source for channel 3 to +dig so that the device records

when the DI pin is high. In the following sequence, <enter> means pressing the Enter/Return

key to execute the command in the shell. With the SSR-1 shell connected to a terminal program,

type

config <enter>

to show the current SSR-1 configuration.

To change the command source for channel 3 to +dig, type

config 3 src +dig <enter>

Verify that the configuration has been changed using:

config 3 <enter>

To save the modified configuration in on-board non-volatile memory so that it is preserved

across power cycles, type:

config save <enter>

To confirm that the configuration has been saved, reboot the SSR-1 and verify configuration

using:

reset <enter>

config <enter>

Note that ‘cfg’ is an alias for ‘config’ and can be used as a shortcut.

SSR-1 Shell [Firmware 1.2.1]

SSR-1 User’s Manual

Rev E, 27 Feb 2018

3Functional Overview

The SSR-1 consists of three asynchronous serial channels, a data recording subsystem, a user

interface module, a real-time clock, and digital input/output for status and control.

3.1 Serial Channels

The behavior of each serial channel is independent and is defined by a number of configurable

parameters, which can be changed using the interactive shell or the control protocol, documented

in Sections 4 and 5, respectively. Those parameters are:

Baud rate –600 to 230400 baud, inclusive

Parity –Even, odd, or none

Stop –1, 1.5 or 2 stop bits.

Echo –(Boolean) Echoes received characters out through the transmitter.

Function

odisabled –The channel is not used.

orecord –The channel will record received data when commanded.

oshell –The channel will be tied to the interactive user shell function of the user

interface module.

ocontrol –The channel will be tied to the control protocol function of the user

interface module.

Note that the user interface module can be attached only to a single channel. If one of the

channels is assigned to either the SHELL or CONTROL functions, no other channel may be

assigned to SHELL or CONTROL.

3.2 Record Function

In addition to the basic serial channel parameters above, when a channel is assigned to the

RECORD function, several other configurable parameters apply:

Command Source

Command Source determines how the channel is commanded to record. Options include

a discrete digital signal, a PWM signal, or software controlled through the user interface

module (shell or control protocol). Command Source for a channel can be set to one of

the following:

o-soft –The channel records when the Soft Command parameter (defined in the

next major bullet) is true. With -soft, Soft Command is set to false at startup, and

the DI and PI pins are ignored.

o+soft –The channel records when the Soft Command parameter is true.

With +soft, Soft Command is set to true at startup, and the DI and PI pins are

ignored. This selection for Command Source causes the channel to automatically

record at startup.
