9.3 Serial Remote Control Interface
The serial remote control interface is enabled when the hardwired remote control inputs
are enabled (i.e. when either 1-5-003 or 1-5-004 TVIR commands are sent, or the
equivalent <OPM>3/ or <OPM>4/ are sent followed by a restart, <RST>1/).
The serial interface defaults to 115.2kbaud, 8 bits, no parity, 1 stop bit (8N1).
If the hardwired remote control inputs remain in a constant state then they will be ignored
and the remote control serial interface commands will be in total control. See the next
section if it is desirable to use both hardwired and serial remote controls simultaneously.
The serial commands applicable to the remote control interface are as follows:

? Returns current PEL-4 state.
(Should be regularly polled due
to internal states being updated
each second).
Day/Night <RDN>B/
1 Active: PEL-4 switches to day
intensity.
0 Inactive: PEL-4 switches to night
intensity.
? Returns current PEL-4 state.
(Should be regularly polled due
to internal states being updated
each second).
The serial interface commands work in a differential mode to the current PEL-4 state. If a
new serial command is received that requires a change in state compared to the existing
PEL-4 state, then a change of state is scheduled and will occur in the next one to two
seconds.
The new state can be identified by polling with the same command and a ‘?’ parameter.
Note that the read-back state will not instantly change after the new command is sent, so
polling is necessary to detect the new state.
For example, if the PEL-4 is in night state and an ‘<RDN>1/’ command is sent to change to
day state, this change will occur within 1 to two seconds of receipt of the command. Read-
back command ‘<RDN>?/’ can be sent repeatedly until the new state is internally
recognised.
The two serial remote control interface commands work independently of each other.
Other PEL-4 modes are compatible with the operation of the remote controls serial
interface, including dual character, effective or peak intensity modes, etc.
