Serial port commands available are shown below
| * | Starts or restarts a command sequence |
| # | Completes an input sequence, Executes command |
| M | Memory, 0 to 9 allowed, single digit |
| P | Plane, 0 to 9 allowed, single digit |
| II | Two digit Input number, 00 to 99 allowed. |
| OO | Two digit Output number, 00 to 99 allowed |
| C | IO Channel number, 0 to 9 allowed, single digit |
| B | IO channel Bit number, 0 to 7 allowed, single digit |
| R | Restore code, 0 to 9, C or D allowed, single digit |
| HH | Two digit Hex value, 00 to FF allowed. |
| VVRR | Version and release numbers |
| Command format | Action | Response code |
| Power up | >00VVRR# | |
| Invalid command | >02# |
These commands take affect immediately
| * M # | Restore memory setting M | >12# |
| * M2 # | Saves links for all planes to memory M | >18# |
| * P0 # | Clear all connections in a plane P | >14# |
| * P1 # | Set links straight i.e. Input 0 to Output 0 , 1 to 1 etc. | >16# |
| * PII1 # | Set input II to all outputs in plane P | >1D# |
Shortcuts to allow the plane 0 to be set quickly
| * OO0 # | Clears link to output OO on plane 0 | >1A# |
| * IIOO1 # | Sets link from input II to output OO on plane 0 | >1C# |
These commands take effect after the Action command
| * # | Action new settings now | >10# |
| * POO0 # | Clears link to output OO on plane P | >20# |
| * PIIOO0 # | Clears link to output OO on plane P, as above | >20# |
| * PIIOO1 # | Sets link from input II to output OO on plane P | >22# |
IO Channel commands these take affect immediately
| * CB # | Read all channels and display channel C | >32HH....# Hex pair for each IO channel configured |
| * CB0 A # | Clear IO channel C, bit B | >30# |
| * CB1A # | Set IO channel C, bit B | >30# |
| * CHHB # | Set all bits of channel C, HH bit pattern in Hex | >34# |
Configuration commands
| * R4 # | Power restore, R=mem. 0-9, C Previous, D None | >1E# |
| * 1A # | Reconfigure MATRIX | >04# |
| * 03 # | Send all configuration data via serial port | >04VVRRHH..# Hex pair for EEPROM and CMOS contents |
