4.6.12 MAC00-FP2 - How to connect the RS232 interface
The illustration below shows how to connect the MAC00-FP2 directly to a PC COM
port. The drawing is based on standard cables from JVL, type WG0402, WG0410 or
WG0420. See also Accessories, page 291 for a complete list of cables and connectors.
If the MAC motor is connected to the same RS232 line as other motors, the terminal TX-
PD should only be connected at one of the motors. If one of JVL's standard RS232 cables
(RS232-9-1 or -n) is used between the DSUB connector shown and the PC com port,
the RX and TX pins must be swapped since they cross in these standard cables.

Connector:
Cable = Female 9pin DSUB
At PC = Male 9pin DSUB
If JVL's standard programming cable type
used between the shown connector and the PC the RX
and TX signal must be swapped. Tx to pin 2 and Rx to pin 3.
4.6.13 Operation with dual supply for emergency situations
In many applications it is intended that positional data and other setup information is re-
tained during an emergency situation. It is however also required by law in many coun-
tries that the main power for energizing the motor is removed in such a situation.
To meet both of these requirements, the MAC motor equipped with a MAC00-FPx
module offers a secondary supply input called "CV". If the main supply at the P+ terminal
is removed, the internal control circuitry can be kept "alive" by maintaining a supply at
the "CV" terminal.

(12-48VDC)
* The "CV" terminal can be left open if not used.
