Operation of the Delux Controller System (DLUX303)
The chambers can be purchased with upgraded controllers. The controllers have
additional features of RS485 communications and analog outputs.
RS485 Communications:
Each controller on the network (connected to the same PC or master device) must be
programmed with a unique address. If multiple chambers are being connected, each
controller will have to be assigned a unique address. Factory defaults for the controllers
are addresses 1 for temperature, 2 for humidity, and 3 for CO2. As an example, a
second chamber would need to be assigned address 4 for temperature, 5 for humidity,
and 6 for CO2. To assign new addresses to controllers, the controllers must be
unlocked. Refer to Section 13, Unlocking the Controllers.
Once the controllers are unlocked on each controller, follow these steps to set a unique
address for each controller:
1) Press and hold the up and down key simultaneously for six seconds.
2) The upper display will read Ai and the lower will read SEt
3) Press the up key until the upper display reads CoM
4) Press the advance key until PCoL appears
5) Set the protocol to either Modbus (Mod) or Standard Bus (Std)
6) Press the advance key until Ad.M (Modbus) or Ad.S (Standard) appears
7) Press up/down to increase/decrease the address number
8) *Press the advance key until bAUd appears
9) *Press the up/down arrow keys to set the baud rate (38.4K is default)
10) *Press the advance key until Par appears
11) *Press the up/down arrow keys to set the
Parity (‘none’ is default)
12) *Press the advance key until M.hL appears
13)
*Press the up/down arrow keys to set the Word Order (‘Lohi’ is default)
14) Press infinity to exit to the main menu
*When using ModBus, other parameters such as Baud Rate, Parity, and Word Order
must be set. Standard Bus only requires a unique address be set.
Once all addresses are entered refer to Section 13 to relock the controllers.
