Note. The 32 inputs are numbered 1 to 32 in section 3.2.3.5, corresponding to
the associated pin on the 40 way input connector, however the handset
command numbers the inputs from 0 to 31, for the 32 inputs.
The controller provides U/D for an Integral OTU. See the Controller Handset
Commands CUD and UDT. Note: These functions only work if they are enabled in
the T400's configuration.
3.3.3.13 Reply bit function (GRL)
GRL{Reply byte no.: 0 to 13} {bit no.: 0 to 7}={function: 0 to 255} (0)
Comment:
The various functions are as follows:
0 =
1 = Red Lamp Monitor group 0 - first red fail (RL1)
2 = Red Lamp Monitor group 0 - second red fail (RL2)
3 = Red Lamp Monitor group 0 - any lamp fail (LF)
4 = Red Lamp Monitor group 1 - first red fail
5 = Red Lamp Monitor group 1 - second red fail
6 = Red Lamp Monitor group 1 - any lamp fail
7 = Red Lamp Monitor group 2 - first red fail
8 = Red Lamp Monitor group 2 - second red fail
9 = Red Lamp Monitor group 2 - any lamp fail
10 = Red Lamp Monitor group 3 - first red fail
11 = Red Lamp Monitor group 3 - second red fail
12 = Red Lamp Monitor group 3 - any lamp fail
33 = Red Lamp Monitor group 4 - first red fail
34 = Red Lamp Monitor group 4 - second red fail
35 = Red Lamp Monitor group 4 - any lamp fail
36 = Red Lamp Monitor group 5 - first red fail
37 = Red Lamp Monitor group 5 - second red fail
38 = Red Lamp Monitor group 5 - any lamp fail
39 = Red Lamp Monitor group 6 - first red fail
40 = Red Lamp Monitor group 6 - second red fail
41 = Red Lamp Monitor group 6 - any lamp fail
42 = Red Lamp Monitor group 7 - first red fail
43 = Red Lamp Monitor group 7 - second red fail
44 = Red Lamp Monitor group 7 - any lamp fail

normal direction loop connects (the reverse direction loop is
connected to the next input after the normal direction loop).
For each reply byte set up the function of each bit in this reply byte.
This command is therefore repeated up to eight times for each reply
byte. The {function} field defines the source that sets the bit, or in
the case of SCOOT loops a group of four bits.
For GRL command, this indicates that the reply bit is driven directly.
For GOL command, this indicates that the output bit is driven directly
from the corresponding UTC control bit.
