(SR) Set Relay Initial Value
Allows the powerup value of the relays to be set. This is useful for initializing the relays to a given state on powerup.
Command:
SR <address> <relay> <state><cr>
Where <relay> is a decimal number 1-4 and <state> is 0 for off and 1 or greater for on. An off state of the relay
corresponds to the NC of the relay connector being connected to the common (C) connection. An on state corresponds to the NO
of the relay connector being connected to the common (C) connection.
Response:
<ACK/NAK><cr>
If <value> is greater than 255 or <input> is outside the 1-4 range, a "NAK" is returned. This value is saved and restored
on powerup.
(RC) Relay Control
Turns relays on or off. These outputs first initialize to off, however this initial state can be changed with the Set Relay Initial
Value command.
Command:
RC <address> <relay> <state><cr>
Where <relay> is a decimal number 1-4 and <state> is 0 for off and 1 or greater for on. An off state of the relay
corresponds to the NC of the relay connector being connected to the common (C) connection. An on state corresponds to the NO
of the relay connector being connected to the common (C) connection.
Response:
<ACK/NAK><cr>
(SE) Set Internal Encoder Initial Value
Allows the powerup value of the internal encoders to be set. This is useful for initializing the encoders to a given state on
powerup.
Command:
SE <address> <input> <value><cr>
Where <input> is a decimal number 1-8 and <value> is 0-255.
Response:
<ACK/NAK><cr>
If <value> is greater than 255 or <input> is outside the 1-8 range, a "NAK" is returned. This value is saved and restored
on powerup.
(EN) Set Internal Encoder Minimum Value
Allows the minimum value of the internal encoders to be set. This is useful for restricting the range of the encoder input(s).
Command:
EN <address> <input> <value><cr>
Where <input> is a decimal number 1-8 and <value> is 0-255.
Response:
<ACK/NAK><cr>
If <value> is greater than 255 or <input> is outside the 1-8 range, a "NAK" is returned. This value is saved and restored
on powerup. If the minimum encoder value is set greater than the maximum encoder value, anomalous operation will occur.
