Source module data line zero. Signals MOD DO
through MOD
D3 are the mm source module
data bus lines (bi-directional).
Data line one.
Data line two.
Data line three.
Source module control line zero. Signals MOD
CO and MOD Cl are the control lines for the
read/write to and from the mm source module.
Control line one.
Source module clamp control (not used).
Source module sense. A
1mA current is injected
on this line by the mm source module to
indicate its presence. This signal always equals
ov.
Low
= RF off. Source module RF is turned off.
Source module external leveling return.
Source module external leveling input, from the
mm source module.

Power supply. Range is +14.25 to +16.4OV
Power supply. Range is i-7.75 to +8.25V.
Power supply. Range is t4.75 to t5.45V.
Digital ground.
