5.11 Expansion Module MAC00-R1/R3/R4
5.11.42 Connecting the RS232 interface of the MAC00-R3 module
The illustration below shows how to connect the MAC00-R3 directly to a PC COM port.
The drawing is based on standard cables from JVL, types WG0402, WG0410 or
WG0420. See also
Accessories, page 448 for a complete list of cables and connectors.
Please remember to connect the TX and TX-PD wires from the MAC00-R3 together to
achieve stable operation.
If the MAC motor is connected to the same RS232 line as other motors, the terminal TX-
PD should only be connected on one of the motors.
If one of JVL’s standard RS232 cables (RS232-9-1 or -n) is used between the DSUB con-
nector shown and the PC com port, the RX and TX pins must be swapped since they
cross in these standard cables.
