Defensive/Offensive Visits

 
High School rules on coaches visiting (conferences) to their offense and defense players are much different than in MLB.
 
How are these situations handled in NFHS:
 
1a. Near the end of the game with the bases loaded in a close game, the 1st base coach (not the head coach) calls time and wants to gather his base runners (but not the batter). Is that legal?
 
1b. During the huddle in question #1a, the pitching coach wants to visit the mound to talk to his pitcher. Can he? Does the visit to the pitcher count as a visit for the defensive team?
 
1c. Two batters and two outs after the huddle in question #1a above, the batter does not understand the 3rd base coach's complicated signs. The 3rd base coach wants time to talk to his batter, can he?
 
1d. When does a coach's offensive visit to the batter begin and when does it end?
 
Call
1a. The offense is permitted one visit per half inning. The offensive coach can meet with the batter and/or the runners -- so 1a is legal.

1b. A defensive coach may visit his pitcher or any defensive player while the offense visits their player. This does not count as a charged conference if it ends when the offense visit ends and the game is not delayed.

1c. Since the offense used their one visit earlier in the inning, the plate umpire cannot allow another offensive conference during that half-inning.

1d. Assuming the offensive conference is the typical visit that occurs between the batter and 3rd base coach (half way between 3rd base and home and in foul ground), the offensive conference concludes when the 3rd base coach initially starts to head back to the 3rd base coach's box.

 
2a. The pitching coach thinks the pitcher is injured (but it does not look obvious to you) and wants to visit him. Does this count as a visit?
 
2b. The pitching coach visits the pitcher twice in the first inning. Must the pitcher be removed on that second visit?
 
2c. The head coach calls time and wants come to the plate to talk with the catcher about the "third and first play". Is that considered a defensive visit? What if the coach calls "time" from the dugout and calls out a play to the catcher without visiting the catcher on the field. Is that a defensive visit?
 
2d. When does a coach's defensive visit to the pitcher start and when does it end?
 
Call
2a. The plate umpire should accompany the coach to the visit and assure that the visit only addresses the injury. If the conversation strays into game strategy, the plate umpire must stop the conversation and warn that if it continues
a defensive visit will be charged.
 
2b. The defensive coach may visit his team (pitcher or any other team member) three times in a 7-inning game, without penalty. After that, the pitcher must be removed. NF 3-4-1 has all the details.
 
2c. A visit to the catcher is a charged defensive conference. Yelling instructions or plays from the bench is not a charged conference.

2d. Assuming the defensive conference is the typical visit that occurs near the pitcher's mound, the conference concludes when the defensive coach crosses back into foul territory on the way back to the bench. If the coach crosses
into foul territory, but then turns to head back out to the mound -- you could charge a second conference, but it is customary to warn the coach that if he continues to the mound, a second conference will be charged.
