APPENDIX E • SERIAL COMMANDS

Error Codes

The following are error messages and their explanations:

ERROR 1 Memory error. The box is out of internal memory. Power cycle the

unit.

ERROR 2 No command found. A command was not found in the string.

ERROR 3 Unknown response. Connect with current G-Ware to upgrade

dictionary.

ERROR 4 Not implemented. The command was not implemented.

ERROR 5 Argument error. The command has an argument that is out of range.

ERROR 6 Unknown command. The command is unknown to this unit.

ERROR 7 Bad checksum. The binary command’s checksum is wrong.

ERROR 8 Preset or macro invalid. A preset or macro failed to program because

it is too large or because its command list contained an invalid

command.

ERROR 10 Queue error. The internal command queue is full. Enable flow control

and use all five pins on the serial port.

ERROR 11 Command too big. The binary command is too large.

Note: Commands can be upper or lower case. Also, extra spaces or tabs between

arguments in text commands is allowed. For a command to be recognized by the

serial port, the command must be terminated with a carriage return.

The command string will then be explained (where necessary), followed by the

returned values and (where necessary) an example.

Conventions

This definition uses the following typographic conventions used in this document:

Convention

Description

<X> Parameters enclosed in < > indicate and mandatory parameter.

[X] Parameters enclosed in [ ] indicate and optional parameter.

1-8 Parameters separated by a - indicate a range between the values.

4,7,9 Parameters separated by a , indicate a list of available values.

MREF Words in uppercase bold indicate command text.

DEVICE Indicates the device type and device number on the Expansion Bus

network. It is composed of a device type character and a device

number. The device type for the PSR1212 is always 4 and the device

Command Summary

Two formats of commands are available in the PSR1212: Text and Binary. All

commands are supported in a binary format and are intended to be used with the

software provided with the unit. Commands that are primarily used to control the unit

are available in text format to support easy interfacing with an external control system

such as those provided by Crestron or Panja.

The RS-232 Serial Port Protocol is 9,600, 19,200, 38,400 (default), or 57,600 baud; 8

bits, 1 stop bit, no parity.
