o
If a photocell is connected, it will always be calibrated and disarmed regardless
of the value in CV50
●
CV66=2 The PSXX output will assume the same state it was in when the connected
booster was last turned off.
o
If the stored power down state is OFF, the PSXX will behave the same as if
CV66=0
o
If the stored power down state is ON, the PSXX will behave the same as if
CV66=1
●
CV66 default is 1. The PSXX will always power up and the photocell [if present] will
always calibrate and be disarmed.
●
In the event that the photocell is calibrated while covered, it will mis-calibrate [it
assumes it is uncovered]. In most cases, simply waiting until the next time the
photocell is armed will solve the problem since it will perform a calibration before
arming. If you want to calibrate the photocell but NOT arm it, send an accessory
OFF command to the second PSXX address. Make sure the photocell is uncovered
when you issue the command. This is useful if you are using the photocell for block
occupancy detection.
CV67
is used to inhibit flashing of the Block Occupied output when the photocell is armed.
●
If CV50=1 and CV66=0, the Block Occupied output will flash whenever the
photocell is armed. The PSXX power output is on.
●
The flashing can be inhibited by setting CV67=1. Any other value of CV67 will
enable the flashing.
●
CV67 default is 0 [flashing enabled].
CV68
blocks Accessory Addresses 1017 to 1020 from being used when CV68=0.
●
This prevents some Digitrax systems from incorrectly programming the PSXX
addresses.
●
Setting CV68=1 enables these addresses. Default=0
J. Special Programming Instructions
Specific DCC Systems need to follow specific programming sequences to reliably
program a PSXX. See Section K for specific system instruction
All systems:
Program CV’s using POM. Do not use Program track or accessory
programming.
If the PSXX is reset [CV63=42], the default address will be 2042, 2043 & 2044. These
addresses are not accessible to Digitrax LocoNet equipment.
For all systems, whenever you enter an address or CV value, you should see D6 flash. This indicates the
PSXX has received the information, stored it, and verified the stored data matches the data you sent.
Lenz
:
The Lenz system sends repeat accessory commands as long as you hold down the 1 or
4 command key. This ensures that the accessory decoder sees the message, but can
result in the same address stored multiple times while programming a PSXX. The solution
is simple:
1. Hold the 1 or 4 key down for only a short time.
