Mount a Share from another NAS to PR4100

Need some hand holding help please - New to using linux

Trying to setup plex - have 2 NAS with data
Trying to map a NFS share from my ix4 nas to my new PR1400
I have posted what information I know to give, so if there is other information that is needed, please let me know, and maybe how to get it.

Lenovo ix4-300d
IP address 192.168.5.14
With a NFS share
Location: /nfs/TVShows
NFSv4 Location: /TVShows
Permissions Everyone read / write

Second NAS Pr4100

Run this command busybox mount -o nolock,ro,hard,intr,vers=3 -t nfs 192.168.5.14:/TvShows /mnt/HD/HD_a2/test

mount: 192.168.5.14:/TvShows failed, reason given by server: Permission denied
mount: mounting 192.168.5.14:/TvShows on /mnt/HD/HD_a2/test failed: Bad file descriptor

Now I am trying to verify if my mount point on my PR4100 is active, but when I try showmount

-sh: showmount: not found

Any ideas - what am I missing

Thanks
