Warnings for TGT-1 Users
1. The datalogger operating system must be compatible for use with the
TGT-1. CR10X dataloggers must have version 1.6 or later. CR500
dataloggers need version 1.4 or later. CR23X dataloggers should have
version 1.4 or later. CR10 and 21X dataloggers require a special PROM.
CR10 PROM is item number 8131-00, 21X PROM is item number
8132-04. Check *B mode for operating system version. If you did not
purchase the TGT-1 and datalogger together, make sure you have the latest
operating system. Contact a Campbell Scientific Applications Engineer if
you have any questions.
2. The datalogger clock must be set to Coordinated Universal Time. All
references to time are based on Coordinated Universal Time.
3. The timing of the P120 instruction should not coincide with the assigned
transmission time. Leave at least a two-minute buffer.
4. If you are using the keypad (CR10KD) when the datalogger initiates a P99,
P120 or P123 instruction, the instruction will fail without reporting a
failure.
5. Due to atmospheric interference and other sources of error, it is possible
for a data transmission to be missed by the ground station. If this happens,
your missed data is still in the datalogger until overwritten by new data.
6. To prevent communication collisions when connecting storage modules
(SM192/716, SM4M, SM16M) and a TGT-1 to the CR10(X) or CR23X,
connect the storage module and then enter the command string
“*91A9A*0” to put the storage module into the SDC mode. This is done
automatically if the storage module is connected to the logger when the
logger is powered up. The same command should be executed when a new
storage module replaces the previous one.
7. Array IDs smaller than 255 are stripped off when data are sent to the
transmitter. Array IDs between 255 and 511 (highest possible) are not
stripped off.
